Arizona Diamondbacks starting pitcher Zac Gallen (hamstring) has been placed on the 15-day injured list on Friday. This is frustrating news after Gallen was removed during his start on Thursday due to a hamstring issue. He is now set to miss time after manager Torey Lovullo said he was hopeful Gallen would avoid a stint on the injured list. In a corresponding move, right-hander Slade Cecconi has been recalled from Triple-A Reno. This seems like a move to add bullpen depth so it's uncertain what the D-Backs plan to do with the vacant rotation spot.

Los Angeles Angels outfielder Jo Adell is out of the starting lineup ahead of Friday's game against the Seattle Mariners. Adell is in the middle of a 1-for-30 slump at the plate. That being said, it's not shocking to see why the Halos would give him a night off. Recently, manager Ron Washington said Adell's starting spot was safe, so that means he should be back in the lineup following this game. In the meantime, Kevin Pillar will cover right field and bat fifth versus right-hander Bryan Woo on Friday.

San Diego Padres starting pitcher Yu Darvish (hamstring) is still being evaluated and could make his next scheduled start. The right-hander was removed from Wednesday's start after three innings due to a left hamstring issue. Depending on how he feels, Darvish could make his next start on Tuesday. Fantasy managers will have to wait and see as the Padres are taking it day-by-day right now. There should be an update on his status within the next day or two.

Boston Red Sox outfield prospect Roman Anthony has performed very well through May at Double-A Portland and is making a case to be moved up to Triple-A later this summer. Since May 1, the number two prospect in the Boston system has held a .280/.415/.453 line with one long ball, two swiped bags, 21 total hits, and an 18:23 BB:K ratio. This is a stark contrast to his April line, where he posted a mere .205/.310/.329 line with a much worse 11:28 BB:K ratio. The 20-year-old got a small taste of Double-A last summer but spent the majority of the season with Single and High-A. MLB Pipeline projects Anthony to reach the majors next season and is worth following closely in dynasty leagues.

Both Texas Rangers right-handers Tyler Mahle (elbow) and Kumar Rocker (elbow) threw bullpen sessions off the game mound recently for a biomechanical evaluation. Both Mahle and Rocker had their Tommy John elbow surgeries on May 22 of last year. A year later, both Mahle and Rocker are beginning to throw off a mound again, but they both still have work to do before they are cleared to start facing live hitters in games. Neither Mahle nor Rocker are likely to return to game action until after the All-Star break in mid-July. The 29-year-old Mahle had a solid 3.16 ERA and 1.05 WHIP with 28 K's and five walks in his five starts for the Twins last year before going down. Rocker, the club's No. 4 prospect per MLB Pipeline, will also be hoping to return to minor-league games in July, but fantasy managers shouldn't expect him to join the big-league club in 2024.
