Arizona Diamondbacks starting pitcher Zac Gallen (elbow) has been officially placed on the 15-day Injured List on Sunday. Gallen was scratched ahead of his scheduled start on Sunday due to left elbow inflammation. He will officially head to the shelf and will hopefully be back in the mix before the end of July. Mitch Bratt will take the mound on Sunday and could remain in the rotation until Gallen is ready to return. Gallen owns a 6.34 ERA, 1.56 WHIP, and a 61/31 K/BB ratio across 98 innings of work this season. Given his struggles, Gallen is really only worth holding in deep leagues at the moment.

Seattle Mariners starting pitcher Emerson Hancock (hand) was forced to make an early exit from Sunday's outing against the Tampa Bay Rays. Hancock was struck in the hand by a comebacker during the first inning of this contest. He remained in the game afterwards, but was pulled in the second inning. His day will be finished with 1.2 innings of work and two strikeouts. The expectation is that Hancock will undergo further testing to determine the severity of the injury. Luckily, the All-Star break begins on Monday, so Hancock will get a few days off to rest. Fantasy managers should consider Hancock as day-to-day until further notice.

Philadelphia Phillies starting pitcher Zack Wheeler has decided to decline an invitation to the upcoming All-Star Game in Philadelphia. Wheeler was asked if he wanted to be a replacement on the National League roster. He declined, stating that he felt disrespected to be the fifth choice as a replacement. Wheeler has been outstanding when healthy this season, so he's certainly deserving of an All-Star nod. The right-hander owns a 2.28 ERA, 0.91 WHIP, and a 98/20 K/BB ratio across 14 starts this season. Wheeler has bounced back nicely since having thoracic outlet surgery last year. He'll rest up during the All-Star break and look forward to helping the Phillies in the second half of the season.

Los Angeles Dodgers relief pitcher Edwin Diaz (elbow) got into his first game action on Saturday, which was the first time he has pitched since undergoing surgery in April. Diaz tossed a scoreless inning, allowing one hit, while striking out two during his outing with Single-A Ontario on Saturday. This is an encouraging step forward as Diaz works his way back from having loose bodies removed from his right elbow. The expectation is that he'll need a few more rehab outings before he's ready to return to the Dodgers bullpen. Fantasy managers can be hopeful that Diaz is back in the mix by late July.
