Seattle Mariners executive vice president and general manager of baseball operations Justin Hollander announced on Wednesday that the team placed right-hander Bryce Miller (elbow) on the 15-day injured list (retroactive to May 12) with right-elbow inflammation and recalled left-hander Jhonathan Diaz from Triple-A Tacoma in a corresponding move. It helps explain why Miller was torched for seven runs on eight hits while walking two over five innings of work in his last outing on Sunday against the Toronto Blue Jays. The 26-year-old received a cortisone shot in his elbow on Tuesday, and the M's are optimistic he'll be able to return from the IL when eligible on May 27. It's possible that Diaz, 28, could take Miller's spot in the rotation and start this weekend in San Diego against the Padres. In his one relief appearance for Seattle this year, Diaz threw 1 1/3 scoreless innings with a strikeout against the Tigers.

Philadelphia Phillies infield prospect Otto Kemp continues to have an impact at Triple-A, going 2-for-4 on Wednesday with an RBI, a stolen base, and two runs scored. The 25-year-old now boasts a .327 AVG with a 1.061 OPS, while his 10 home runs are tied for the most in the International League and his 37 RBI are the second-most. The right-handed hitter could be in the majors by the end of the month or shortly thereafter, and with some solid power, he could be impactful enough to roster in deeper fantasy leagues. Plus, he has eligibility at both 2B and 3B on Yahoo!, so interested managers should watch for news of a promotion.

San Francisco Giants catcher Patrick Bailey is taking the day off in Thursday's series finale against the division-rival Arizona Diamondbacks with left-hander Eduardo Rodriguez on the mound. Sam Huff will do the catching for right-hander Jordan Hicks and will bat seventh in the batting order. Bailey has had a rough go in the 2025 season to this point and is still searching for his first home run. The 25-year-old switch-hitting backstop has gone 20-for-112 (.179) with 12 RBI, 11 runs scored and a 40:7 K:BB in 38 games. He's gone 7-for-35 (.200) with two doubles, three RBI and 11 strikeouts in the last two weeks over 11 games. DFS managers should have better sleeper options than Huff at catcher. Huff has been just as bad as Bailey in 37 at-bats, hitting .189 with a homer and three RBI. The 27-year-old has never faced E-Rod in his career.

Washington Nationals pitching prospect Travis Sykora (hip) has been activated from the injured list and is slated to start for Single-A Fredericksburg on Wednesday. The former third-overall draft pick made two rehab starts with the team's Florida Complex League affiliate, allowing one earned run on one hit and one walk while striking out a whopping 14 batters in only five innings of work. The 6-foot-6 hurler displayed tremendous strikeout stuff last year as well in his first taste of professional baseball, posting a 2.33 ERA, 0.91 WHIP, and a 39.2 percent strikeout rate (31.0 percent K-BB%) in 20 starts (85 IP). If all goes well, expect the righty to get a bump to High-A or even Double-A later this year. Washington's top-ranked prospect has an ETA of 2027 per MLB.com, but looks like he's got the potential to arrive sooner than that.

Philadelphia Phillies pitching prospect Mick Abel allowed just one earned run in his latest start, yielding three hits and two walks whilestriking out nine over seven innings of work. The former first-round draft pick started the season well, pitching to a 3.80 ERA, 1.45 WHIP, and an 18.5 percent K-BB% over his first four starts, but has taken it up a notch over his last four, posting a 1.44 ERA, 1.00 WHIP, and a 15.0 percent K-BB% during that time. It is a vast improvement over lastseason's 6.46 ERA, 1.81 WHIP, and 7.6 percent K-BB% that the righty logged in 24 starts, all at Triple-A. The 6-foot-5 hurler looks to be on the doorstep to the majors, so if he continues to pitch well, look for a call-up later thisseason. He isn't a must-stash, but with his big frame and pitch-mix, he has the ability to be a solid big-league starter from the get-go, so fantasy managers shouldkeep a watchful eye out for news of a promotion.
