The Baltimore Orioles announced that they optioned infield prospect Coby Mayo to Triple-A Norfolk after Thursday's game to make room for the return of outfielder Tyler O'Neill (neck) from the 10-day injured list. Although Mayo played in just four games in his second stint in the big leagues after a disappointing debut performance in 2024, he had just one hit in 12 at-bats with a walk and six strikeouts, and he also didn't endear himself to the coaching staff with his play on defense. In his first 21 big-league games, the team's No. 2-ranked prospect per MLB Pipeline, has gone 5-for-53 (.094) with no homers or RBI, five walks and 28 strikeouts. Mayo will head back to Norfolk for the time being but should rejoin Baltimore sooner than later as he looks to finally break through at the major-league level this year. Fantasy managers in dynasty/keeper leagues are getting frustrated.

Baltimore Orioles prospect Coby Mayo is starting at third base and is batting seventh for Sunday's series finale against the visiting Kansas City Royals and right-hander Michael Lorenzen. Mayo, the team's No. 2 prospect per MLB Pipeline, was promoted from Triple-A Norfolk on Saturday and came off the bench in the 4-0 loss to go 0-for-2 with a strikeout. The 23-year-old should see regular playing time at the hot corner for Baltimore with both Jordan Westburg (hamstring) and Ramon Urias (hamstring) on the injured list, making him attractive in deep-mixed fantasy leagues for the short-term. In his MLB debut in 2024, Mayo was overmatched, going 4-for-41 with 22 strikeouts. He had an impressive .869 OPS with Norfolk before his promotion, though, so those that have him in dynasty/keeper leagues will be hoping he'll fare better this time around.

The Baltimore Orioles are promoting third base prospect Coby Mayo, who is set to join the major league roster before Saturday's contest against the Kansas City Royals. Mayo made his MLB debut last season but struggled during his first stint. Across 17 games, Mayo posted an underwhelming .098/.196/.098 slash line with just four hits (all singles). He posted a 22:4 K:BB. However, at the Triple-A level, Mayo has flashed elite upside. Earlier this season, the No. 2-ranked prospect in the Baltimore system posted an impressive .252/.346/.523 slash line with seven doubles, six home runs with a 27:16 K:BB. Last summer, Mayo held a .287/.364/.562 line across 89 games at Triple-A. Fantasy managers should monitor his status in the majors as he could eventually carve out a full-time role in the Baltimore starting nine. Given his power upside, he should be added to all standard leagues for the time being.

Baltimore Orioles corner infield prospect Coby Mayo hasbegun to catch fire at Triple-A Norfolk, going 3-for-4 with a walk, a double, two home runs, three RBI, and two runs scored on Wednesday. It was the 23-year-old's fourth multi-hit game in his last six, going 9-for-23 (.391) over that stretch and pushing his slash line up to .268/.368/.567 for the year, with six home runs and a 16:26 BB:K in 26 games (117 PA). Baltimore's second-ranked prospect continues to be the odd-man out for playing time, as the O's recalled 28-year-old corner infielder Emmanuel Rivera from Norfolk on Tuesday after Jordan Westburg hit the IL. Despite a 47.8 percent strikeoutrate in his 46-plate appearance debut last season, the 6-foot-4 slugger should get another chance in Baltimore this season, or elsewhereif they have no intentions of using him in the majors, but whenever he's recalled, power needy managers in deep leagues should considerrostering MLB's 13th-ranked prospect.

Baltimore Orioles third base prospect Coby Mayo has gotten going after a 3-for-24 (.125) start to the season, now 16-for-54 (.296) over the last 14 contests, including five doubles, a triple, and three home runs with a 10:16 BB:K over that stretch. Mayo had a brief, disappointing stint with the O's last year, going 4-for-41 (.098) in his 17-game audition. The results should be betterthe next time around, which should happen around midseason, so long as he continues to hit. The 6-foot-4 slugger offers a big-time power stroke with a solid eye, so he could be an impactful fantasy contributor once he's a mainstay in the big leagues. The Orioles' second-ranked prospect could be a stash candidate in deep leagues if it looks like he's getting closer to a promotion.

Baltimore Orioles third base prospect Coby Mayo went 3-for-5 with a double, a home run, and three RBI during their contest against Triple-A Omaha on Wednesday. This was Mayo's second three-hit game of the young season. In addition, the top third base prospect has begun to find his power as he has gone deep three times over his previous four contests. Over his last nine contests, Mayo has tallied at least one hit in all but one contest. During this stretch, the 23-year-old has posted a stellar .343/.442/.714 slash line with seven extra-base hits. Mayo reached the majors last summer but tallied just four hits across his 17-game stint. Fantasy managers should expect Mayo to contend for an early return to the big leagues if he continues to perform well at Norfolk.

Baltimore Orioles infield prospect Coby Mayo has begun to find his power at Triple-A. After starting the Triple-A regular season, posting an underwhelming .125/.267/.250 line with one long ball, Mayo has begun to flip the script. He has gone deep in each of his previous two games and is riding an impressive seven-game hitting streak. During this streak, Mayo has held a .360/.469/.720 slash line with three doubles, two round-trippers, and eight RBI. He has also shown a strong eye at the plate, posting a 6:7 BB:K. Last summer, Mayo made his MLB debut but tallied just four hits (all singles) across his first 17-game stint. Fantasy managers should continue to monitor his status as Mayo could push for a return to the majors. However, he may need to wait for an injury in the Baltimore infield to be in contention.

Baltimore Orioles third base prospect Coby Mayo went 3-for-5 with a home run during their victory over the Durham Bulls on Sunday. After going 0-for-7 at the plate during his first two games of the season, Mayo was able to break his slump on Sunday. In this contest, Mayo tallied six total bases, brought in two runs, and scored one himself. The 23-year-old was competing for a spot on the Opening Day roster but was unable to find his footing during camp. Fantasy managers should pay close attention to his progression at Triple-A, as he should be in the mix to return to the big leagues early in the campaign. Last season, Mayo posted a .098/.196/.098 slash line across his first 17 games in the majors. However, at Triple-A, he posted an elite .287/.364/.562 slash line. If he continues to hit for power at Triple-A, he will be worth stashing in deeper formats.

Baltimore Orioles third base prospect Coby Mayo was optioned to Triple-A Norfolk. Mayo was competing for a spot on the Opening Day roster but will instead continue his development at the top level of the minor leagues. During camp, Mayo held an underwhelming .190 AVG with a poor 13:2 BB:K. The 23-year-old made his MLB debut last season and posted a .098/.196/.098 line across 17 contests. During this stretch, he tallied just four hits and held a 4:22 BB:K. However, Mayo flashed elite upside at the Triple-A level as he held a .287/.364/.562 slash line with 23 doubles and 22 home runs across 89 contests last season. Fantasy managers should continue to monitor his development with Norfolk, as he will likely be in the mix to return to the majors later in the summer.

Baltimore Orioles third base prospect Coby Mayo (hand) is OK after being hit by a pitch on his right hand in Monday's Grapefruit League contest against the division-rival Boston Red Sox, according to manager Brandon Hyde. The skipper added that Mayo will be checked out on Tuesday, but he expects everything to be OK. It's great news for Mayo, who was in a lot of pain after being hit by a 96 mph sinker. It's possible that the 23-year-old could be back in spring training action by Wednesday. The former fourth-rounder in 2020 came into Monday's spring game hitting just .180 (7-for-39) with three doubles, three RBI, eight runs scored and 13 strikeouts in 42 plate appearances over 16 games. Mayo made his big-league debut in 2024 but struggled by going 4-for-41 (.098) with four walks and 22 K's in 17 games played. He's going to begin the year at Triple-A Norfolk but should once again see time in the majors at some point, likely as a backup.

Baltimore Orioles third base prospect Coby Mayo has gone 1-for-20 at the plate in the Grapefruit League. Mayo's lone hit did not go for extra bases. The former fourth-round pick is considered one of the top third base prospects in the sport. Last season, Mayo flashed immense power upside in the minor leagues. In 89 games with Triple-A Norfolk, Mayo posted a .289/.364/.562 slash line with 23 doubles and 22 long balls. He held a 40:97 BB:K ratio and added four swiped bags. However, during his brief taste of the majors, Mayo took a significant step back. In 17 contests, Mayo tallied just four hits and held a .098/.190/.098 slash line. He generated a low .170x BA with a 21.2 percent hard-hit rate. If Mayo continues to struggle during camp, he may begin the season at the Triple-A level. When he does return to the majors, he will likely compete for starts as a designated hitter as Jordan Westburg should see most of the opportunities at the hot corner.

Baltimore Orioles general manager Mike Elias said the team is expecting big things from third base prospect Coby Mayo in 2025. "I think the fact that he got his debut out of the way is a really good thing," Elias said. "I think that's big for young hitters these days. He's somebody that we think is poised to be a huge contributor this year, so we'll give him a strong look and every opportunity." The 23-year-old hit .287 with 23 doubles, 22 homers, 67 RBI and a .925 OPS in 89 games in the International League in the minors, but he went 4-for-41 (.098) with no homers and 22 strikeouts in 46 trips to the plate in his first 17 big-league games late in the year. He's working to improve his glove this spring and will stay at the corners in camp, but he's not guaranteed an Opening Day roster spot, and his future in Baltimore could be at first base. After his struggles with the O's last year, Mayo is a perfect buy-low candidate in dynasty leagues.

MLB Pipeline named third baseman Coby Mayo Baltimore's top-hitting prospect of the 2024 season. Mayo, who is currently considered the top prospect in Baltimore and No.8 overall, posted a strong .287/.364/.562 slash line across 89 games at Triple-A Norfolk. Mayo launched 23 doubles, 22 home runs, and 67 RBI in this span, with a 40:97 BB:K ratio. This was Mayo's second extended look at the top level of the minors, as he logged 62 games at this level during the 2023 campaign. Mayo was then rewarded with a big league promotion later in the summer but struggled to adjust as he held an underwhelming .098/.196/.098 line with no extra-base hits. Given his stellar performance at Triple-A, his brief slump at the majors presents an intriguing buy-low window in dynasty formats. Fantasy managers should closely monitor his progress during Spring Training as he could make the 2025 Opening Day Roster.

The Baltimore Orioles will option rookie infielder Coby Mayo to Triple-A Norfolk on Saturday, according to a source, which likely means that veteran infielder Ramon Urias (ankle) is coming off the 10-day injured list. Jordan Westburg (hand), who is recovering from a fractured hand, is likely not far behind Urias. With both Urias and Westburg out of late, the O's had been using a combination of Mayo and Emmanuel Rivera at the hot corner. Mayo, the team's top prospect per MLB Pipeline, went 3-for-24 with 12 strikeouts in 10 games since being brought up from Norfolk at the beginning of September. The 22-year-old still has a bright future in the big leagues, but he clearly isn't ready for big-league pitching and could use some more seasoning on the farm. Expect the O's to use a combination of Urias and Westburg at third the rest of the regular season and into the playoffs.

Baltimore Orioles rookie infielder Coby Mayo finds himself on the bench for Wednesday's contest at Fenway Park against the division-rival Boston Red Sox. Mayo will start on the pine in favor of Emmanuel Rivera at the hot corner, and he'll hit in the nine-hole against Red Sox right-hander Nick Pivetta. It continues to be a platoon setup at the hot corner in Baltimore between Mayo and Rivera with both Jordan Westburg (hand) and Ramon Urias (ankle) on the injured list. Mayo, the team's top prospect and eighth overall in all of MLB, has not taken advantage of his opportunity with both Westburg and Urias out and has looked overmatched at the plate in his first 32 at-bats with the O's. Mayo has gone 3-for-32 (.094) with no homers, no RBI, no stolen bases and three runs scored in his first 13 games at the major-league level.

Baltimore Orioles rookie third baseman Coby Mayo and outfielder/designated hitter Eloy Jimenez will both start Monday's game on the bench against the Chicago White Sox at Camden Yards. Emmanuel Rivera will get the start at third base and will bat ninth, while Austin Slater will start in right field and bat seventh against White Sox right-hander Chris Flexen. Anthony Santander is the designated hitter and is batting cleanup. Mayo, the team's top prospect per MLB Pipeline, got the call-up on Sunday when rosters expanded and went 1-for-2 with a run scored and a strikeout in just his eighth big-league game. The 22-year-old has only two hits and 11 strikeouts in his first 23 major-league plate appearances in Baltimore, but he figures to see the majority of playing time at the hot corner for the O's with both Ramon Urias (ankle) and ...

Baltimore Orioles third base prospect Coby Mayo rejoined the major league roster this weekend and will get the starting nod at the hot corner on Sunday afternoon. He will bat in the six-hole. Mayo got a brief stint in the major leagues earlier in August and held a disappointing .059/.200/.059 line across a seven-game stint. However, in Triple-A, the budding star posted an excellent .293/.369/.574 slash line with 22 home runs, 23 doubles, and 67 RBI across an 87-game sample size. Fantasy managers should expect the No.9 ranked prospect in baseball to continue to split time at the hot corner with Ramon Urias during the stretch run. DFS players should consider the power-hitting infielder this afternoon as he faces Colorado left-hander Ty Blach at the hitter-friendly Coors Field.

Baltimore Orioles third base prospect Coby Mayo is set to rejoin the major league roster when the rosters expand, according to Matt Weyrich of the Baltimore Sun. The budding star got a brief taste of the major leagues earlier this summer but struggled as he went 1-for-17 across his first seven major league games. However, at Triple-A this season, the former fourth-round pick posted an incredible .293/.369/.574 slash line with 22 home runs, 23 doubles, and 67 RBI. Even though Mayo struggled through his first stint in the big leagues, fantasy managers should look to add the No.9 prospect in the sport, according to MLB.com, where he is available. He has high power potential and could still find an everyday role in the Baltimore lineup if he settles in at the plate.

Baltimore Orioles third base prospect Coby Mayo hit his 21st Triple-A homer of the season on Wednesday night for Norfolk. The stud prospect has torn up Triple-A this season but did not do much in his first stint in the major leagues. The 22-year-old was 1-for-17 after his call-up to Baltimore. That being said, he has pretty much mastered Triple-A and could get another shot before the season is over. Much like Jackson Holliday, his teammate who also struggled in his first MLB shot, Mayo is worth hanging onto this season in case he is promoted once again. Sometimes a bit of the pressure is removed in the second go-around in the majors for top prospects and that could be the case for Mayo. The talent is clearly there.

The Baltimore Orioles optioned rookie infielder Coby Mayo to Triple-A Norfolk on Thursday and recalled infielder Livan Soto from Norfolk in a corresponding move. Mayo finally recorded his first MLB hit in his seventh game on Wednesday night at Camden Yards against the Washington Nationals, but for now he'll head back to the farm to continue his development. The team's No. 2 prospect, per MLB Pipeline, had an opportunity for regular playing time at third base in Baltimore with Jordan Westburg out with a fractured hand, but he wasn't able to take advantage, going 1-for-17 (.059) with three walks and 10 strikeouts in his first 20 big-league plate appearances. The 22-year-old still has a lot of long-term fantasy upside and should return when rosters expand in September, but for now, veteran Ramon Urias will handle most of the starts at third for the O's.
