Chicago White Sox catcher Kyle Teel (hamstring) said his injured right hamstring is "still grabbing at him a little bit," which is why he didn't start a minor-league rehab assignment with Triple-A Charlotte earlier this week as was previously scheduled, according to Connor McKnight of the Chicago Sports Network. The 24-year-old also said that he's improving from a hamstring strain that he suffered in mid-March while playing in the World Baseball Classic for Team Italy. Teel won't be able to make his 2026 season debut until some point in early May, most likely. Until then, the Pale Hose will continue to mix and match at the catching position at the big-league level with Edgar Quero and Reese McGuire. Teel is only 11% rostered in Yahoo leagues currently, but he'll be worth a look soon off the waiver wire once he's on the verge of coming off the 10-day injured list. The former 14th overall pick in 2023 out of Virginia has the most offensive upside of any White Sox catcher and should see most of the starts behind the dish when he's active.

Colorado Rockies infielder Willi Castro (knee) left Thursday's series finale against the visiting San Diego Padres at Coors Field after three innings with right-knee soreness, according to Patrick Saunders of The Denver Post. Castro was replaced by Tyler Freeman at second base. Before leaving with his knee injury, Castro went 0-for-1 at the plate with a walk and a strikeout. It remains to be seen if Castro will be available on Friday for the team's series opener in New York against the Mets at Citi Field. The 28-year-old Puerto Rican switch-hitter has been playing regularly for the Rockies in the first month of the season, and he came into Thursday's game slashing .250/.311/.353 with a .664 OPS, one home run, nine RBI, 10 runs scored, and two stolen bases in 68 at-bats. Castro offers modest power/speed numbers as a utility infielder for fantasy managers in NL-only leagues, but you can avoid him in mixed leagues. He's currently rostered in just 14% of Yahoo leagues.

The Texas Rangers announced on Thursday that they placed left-hander reliever Robert Garcia (shoulder) on the 15-day injured list with left-shoulder inflammation and selected the contract of right-hander Peyton Gray from Triple-A Round Rock in a corresponding move. Because the 29-year-old southpaw hadn't pitched in a week, he'll be eligible to return from the IL on May 5. Garcia had a 2.95 ERA, 1.25 WHIP, his first nine career saves, and a 68:22 K:BB in a career-high 64 innings for the Rangers in his first year with the team in 2025, but he had yet to pick up a save before his shoulder injury in his first nine outings this year. Right-hander Jakob Junis has so far been tasked with save situations for the Rangers, limiting Garcia's fantasy appeal in all formats. He will now be out at least two weeks, and he's only rostered in 10% of Yahoo leagues.

Texas Rangers right-hander Jack Leiter (ankle) said that his right ankle is "a little sore" after his fall during his start on Wednesday against the Pittsburgh Pirates at Globe Life Field, but he doesn't expect to miss any time because of it as of now, according to Shawn McFarland of The Dallas Morning News. Leiter's next start is scheduled to come on Monday against the New York Yankees, which is a matchup that most fantasy managers will want to avoid in deeper leagues. The 26-year-old tripped over a weighted bat that was in the on-deck circle and fell to the ground in the fifth inning against the Bucs on Wednesday. Leiter took a no-decision while giving up four runs (three earned) on five hits while walking two and striking out five in his five innings of work. The former second overall pick in 2021 out of Vanderbilt has been pretty inconsistent through five 2026 starts, posting a 4.97 ERA (3.81 FIP) and 1.46 WHIP with 29 punchouts and 11 walks in 25 1/3 innings pitched.
