The Seattle Mariners are expected to promote top infield prospect Cole Young to the major leagues. Young is currently considered the No. 43-ranked prospect in the sport and the No. 3-ranked in the system. Young has spent the first two months of the season with Triple-A Tacoma. Through his first 54 games at that level, Young has held his own, posting a .277/.392/.461 slash line with 13 doubles, five triples, five home runs, and four stolen bases. He has held a 28:31 K:BB and tallied 39 runs with 26 RBI. Last summer, Young spent his entire season with Double-A and posted a .271/.369/.390 line. Fantasy managers should expect the former 21st overall pick to spend most of his time at the keystone, with J.P. Crawford viewed as the everyday shortstop. Given his production at Triple-A this season, Young is worth adding in all standard formats.

Seattle Mariners infield prospect Cole Young went 5-for-6 with two doubles, two RBI, and a stolen base during their contest against Triple-A Salt Lake. This was Young's third-straight game tallying at least one hit. Over his last 13 contests, the No. 3-ranked prospect in Seattle has only gone hitless once and held a strong .393/.469/.732 slash line with six doubles, two triples, three home runs, and three swiped bags. Through 52 total games at Triple-A this season, Young has looked quite comfortable, posting a .277/.384/.465 line with five home runs and four stolen bases. Fantasy managers should continue to closely monitor Young's development as he could push for his MLB debut in the coming weeks. If he continues to perform at this level, he would be a viable stash candidate in deeper formats.

Seattle Mariners infield prospect Cole Young went 3-for-5 with a home run, three RBI, and a stolen base on Sunday for Triple-A Tacoma. The former first-round draft pick has caught fire in May, hitting .385 with a 1.222 OPS since May 3, including seven doubles, three triples, and five home runs in 20 games. All three stolen bases he's tallied for the year came in this stretch as well. Carrying a .260/.372/.443 so far in 2025, the 21-year-old also possesses a keen eye at the plate to go along with strong contact skills, registering an impressive 26:27 BB:K through 226 plate appearances. The Mariners' third-ranked prospect is making a formidable case for a call-up to the majors, which could come as soon as sometime in June. The left-handed hitter is eligible at both 2B and SS on Yahoo!, and is one of the top priority prospect stashes in very deep and AL-only leagues.

Seattle Mariners infield prospect Cole Young went 3-for-7 with a double, a triple, and a home run during Friday's contest against Triple-A Albuquerque. Young tallied four RBI and two runs. Over his last 12 contests, Young has been swinging a hot bat, posting a .426/.509/.872 slash line with five doubles, two triples, four home runs, with a 5:6 K:BB. Last season, the No. 3-ranked prospect in the Seattle system spent his entire campaign with Double-A. Across 124 games, Young posted a strong .271/.369/.390 slash line with 25 doubles, nine home runs, and 23 stolen bases. Given his steady play at Triple-A this season, fantasy managers should continue to monitor his development as he should be in the mix to make his MLB debut this summer.
