The Chicago White Sox have activated right-handed pitcher Jonathan Cannon (back) from the 15-day IL prior to his start on Sunday against the San Francisco Giants. In a corresponding move, the White Sox have sent right-handed pitcher Wikelman Gonzalez to Triple-A Charlotte. Cannon has been on the injured list since the start of June with a back strain. Before his injury, the 24-year-old posted a modest 4.66 ERA with a 1.40 WHIP through his first 63 2/3 innings with the White Sox. He tallied just 51 strikeouts and held a 7.5% walk rate. Under the hood, Cannon generated a 4.66 xERA and a .268 xBA, which are both well above the average marks. Fantasy managers should not view Cannon as a viable streaming option facing the Giants this afternoon.

Chicago White Sox starting pitcher Jonathan Cannon (back) will be activated off the 15-day injured list and start against the San Francisco Giants on Sunday. Cannon has been sidelined since early June due to a lower back strain. He only made one rehab appearance where he threw three scoreless innings. That being said, Cannon probably isn't stretched out yet, so he could be limited on Sunday. He has a 4.66 ERA, 1.40 WHIP, and 51/21 K/BB ratio across 12 games (10 starts) this season. Cannon isn't a recommended streaming option for Sunday's slate.

Chicago White Sox right-hander Jonathan Cannon (back) is being sent to Triple-A Charlotte to begin a minor-league rehab assignment this week, according to 670 The Score's Bruce Levine. Cannon thinks he'll need just one or two rehab starts before coming off the 15-day injured list. The 24-year-old should have a rotation spot waiting for him in Chicago when he's ready. Cannon has been out since early June due to a lower-back strain, but he could be back in early July to close out the first half of the season if he's able to avoid a setback during his short rehab stint on the farm. In his first 12 appearances (10 starts) this year, Cannon posted a 4.66 ERA (4.89 FIP) and 1.39 WHIP with 51 strikeouts and 21 walks in 63 2/3 innings pitched. Cannon has never been much of a strikeout guy and relies on ground balls for the worst team in the American League, so his fantasy value is limited to AL-only leagues.

Chicago White Sox general manager Chris Getz said that right-hander Jonathan Cannon (back) is expected to go on a minor-league rehab assignment soon. It's good news that Cannon is getting close to returning to game action, but with Aaron Civale now in Chicago's starting rotation after being acquired in a trade from the Milwaukee Brewers on Friday, there's one less rotation spot available in the Windy City. The 24-year-old former third-rounder in 2022 out of Georgia went 2-7 with a 4.66 ERA (4.90 FIP) and 1.39 WHIP with 51 strikeouts and 21 walks in 63 2/3 innings over 12 outings (10 starts) this year before his back injury landed him on the 15-day injured list on June 13. Barring a setback once he begins his rehab assignment, Cannon could be back in the big leagues with the Pale Hose before the end of June.

Chicago White Sox manager Will Venable said Monday that starting pitcher Jonathan Cannon (back) will be evaluated in the coming days for his lower back. Cannon struggled in Monday's 13-1 loss to the Tigers. The 24-year-old managed just three innings, allowing five runs on four hits (including three home runs) and three walks with five strikeouts. Cannon said after the game about his back, "Bothered me a little bit out there, but I chose to go out there and try to compete". Fantasy managers should keep an eye out for news later in the week to get a better idea as to when Cannon may make his next appearance. He has gotten varying results this season and is now 2-7 with a 4.66 ERA, a 1.40 ERA, and a 7.21 K/9 rate in 12 appearances (10 starts) and 63 2/3 IP.

Chicago White Sox right-hander Jonathan Cannon (back) will make his next start on Tuesday against the hosting New York Mets at Citi Field, according to the Chicago Sun-Times' Kyle Williams. Cannon was scratched from his last scheduled start on Saturday against the Texas Rangers due to tightness in his lower back, but he's obviously feeling better now and will give it a go in a tough matchup against the Mets on the road this week. Even though the 24-year-old has pitched well with three quality starts in four outings in the month of May, Cannon will be a pretty risky fantasy streamer on Tuesday. Overall, the former third-rounder in 2022 out of Georgia has gone 2-5 with a 3.76 ERA and 1.31 WHIP with only 42 strikeouts and 17 walks in 55 innings over 10 outings (eight starts). He'll be going up against a Mets team that ranks ninth in MLB with a .732 OPS.

Chicago White Sox right-hander Jonathan Cannon (back) has been scratched from his start on Saturday against the Texas Rangers due to lower-back tightness and is listed as day-to-day, according to MLB.com's Scott Merkin. With Cannon hurting, right-hander Bryse Wilson will make the start at Rate Field. It sounds like Cannon might be able to avoid a trip to the injured list, but it's unclear when he'll be able to take the mound again. The 24-year-old has only 42 strikeouts in 55 innings over his 10 outings (eight starts) this year, but he's been decent with a 3.76 ERA (4.06 FIP) and 1.31 WHIP in his second year in the big leagues. The Rangers are an excellent matchup with a .651 OPS (fourth-worst in baseball), but Wilson will still be a volatile and risky fantasy streamer on Saturday. In his four starts in 2025, he has allowed 13 earned runs on 27 hits (four homers) with eight walks and 10 K's in 17 2/3 frames.

The Chicago White Sox plan to use right-hander Jonathan Cannon as their bulk reliever on Tuesday against the hosting Cincinnati Reds at Great American Ball Park after left-handed opener Brandon Eisert. It will be the second time this year that Eisert has been the opener, with his first coming on April 27 against the Athletics, when he allowed one run on two hits in an inning in an eventual 3-2 loss. Cannon last served in a bulk-relief role after an opener on April 29 against the A's and allowed three earned runs in 7 2/3 innings for a quality start and his longest outing of 2025. The 24-year-old former third-rounder in 2022 out of Georgia has a solid 3.30 ERA in his last five outings, but he well below-average 17.3% strikeout rate in his two MLB seasons and will be facing a dangerous Reds offense in a hitter-friendly ballpark.

Jonathan Cannon earned the win in Saturday's 10-3 victory over the Athletics, allowing three earned runs in seven-and-two-thirds innings on six hits and two walks while striking out five. It was Cannon's first win of the season, now the owner of a 1-3 record, 4.50 ERA, 1.44 WHIP, and a 7.0 percent K-BB%. The 24-year-old has a career ERA of 4.49, a WHIP of 1.35, and a 6.79 K/9. That, combined with pitching for the White Sox, means wins may come few and far between for the righty, and good performances like Saturday's will be hard to forecast (the A's were heavy favorites in this one), so Cannon isn't an appealing streamer or DFS option despite Saturday's effort.

Chicago White Sox right-handed starter Jonathan Cannon logged a quality start against the Kansas City Royals on Tuesday, giving up one earned run on one hit with three walks and two strikeouts. Cannon was extremely effective in his 94-pitch outing. He lowered his ERA to 4.11 in 13 games (11 starts). He has just 46 strikeouts in 70 innings, making him a bit of a risky option for fantasy managers. This start is a great sign, but the 24-year-old will need to show more consistency and strikeout potential to be a good fantasy option.

Chicago White Sox rookie right-hander Jonathan Cannon will make his return to the big leagues and start on Saturday against the division-rival Royals in Kansas City. Cannon made his first 10 big-league appearances (eight starts) for the Pale Hose in the first half and went 1-3 with a 4.41 ERA (4.18 FIP) and 1.31 WHIP with 39 strikeouts and 13 walks in 51 innings pitched. The 23-year-old former third-round pick in 2022 out of Georgia gave up four earned runs in six innings in his last outing as a bulk reliever last Friday against the Pittsburgh Pirates. Cannon's last start was a quality start on July 7 against the Marlins, when he went six innings while giving up an earned run with four walks and three K's. He'll be making at least two starts in Chicago's rotation to open up the second half of the season, but he'll need to pitch well to stick around. Cannon gave up just one run in five innings in his MLB debut against KC on April 17, but this Saturday will be a matchup to avoid.
