This week, Zack Wheeler is on the verge of his season debut with the Phillies. The Athletics lose Brent Rooker to an oblique strain. Jeremy Peña is sidelined with a hamstring strain.

And we anxiously await updates on Nick Pivetta and Christian Yelich. Let's break it all down and more from around the league in the latest MLB Injury Report.⚾️ Baseball is back! MLB returns to NBC and Peacock in 2026!

In addition to becoming the exclusive home of Sunday Night Baseball, NBC Sports will broadcast MLB Sunday Leadoff, “Opening Day” and Labor Day primetime games, the first round of the MLB Draft, the entire Wild Card round of the postseason, and much more.Jeremy Peña (hamstring)Peña was pulled from Saturday’s game against the Mariners with what was described as right posterior knee tightness. After he was held out on Sunday for evaluation, the team placed him on the 10-day injured list with a Grade 1 hamstring strain. There’s no timeline for a return, but in a best-case scenario, he could be back before the end of the month.

It’s been a rough start for the 28-year-old shortstop. He missed a couple of weeks this spring recovering from a fractured ring finger. While he started the season on the active roster, he didn’t play in back-to-back games until April 3-4.

With Peña out, Isaac Paredes steps in at third base, with Carlos Correa sliding over to shortstop.Brent Rooker (oblique)You knew it wasn’t going to be good when Rooker departed in the middle of an at-bat in the first inning against the Yankees on Thursday. The 31-year-old slugger was in clear discomfort from his side following a swing. The team called it “right flank discomfort” before a proper right oblique strain diagnosis that landed Rooker on the 10-day injured list.

There’s been no word on the severity of the injury, but it would be a shock to see him back before the end of the month. Zack Gelof was recalled from Triple-A Las Vegas to take his place on the active roster, but it’s Carlos Cortes who should benefit from playing time in Rooker’s absence. Cortes has some batting average upside and sneaky pop, streamable in deeper leagues against right-handed pitching, especially when the A’s are at home.Brent Rooker left today's game after appearing to injure himself on this swing pic.twitter.com/SqQxypVZMc— Athletics on NBCS (@NBCSAthletics) April 9, 2026Nick Pivetta (elbow)Pivetta exited Sunday’s start against the Rockies after three scoreless innings with right elbow stiffness.

Anything elbow-related has the potential for an extended absence, but more news on the status of the 33-year-old right-hander should be known on Tuesday. Pivetta was bouncing back well from his six-run outing in his first start, giving up two runs over his next 13 innings. We’ll be on the lookout for an update on Tuesday.Adley Rutschman (ankle)Ryan Mountcastle (toe)Rutschman was scratched from Saturday’s lineup against the Giants with ankle soreness and placed on the 10-day injured list with ankle inflammation.

An MRI revealed no structural damage, so there’s a great chance we see Rutschman return either when first eligible or shortly after. Samuel Basallo steps in as the primary backstop, opening more DH duties for Dylan Beavers, who has started each of the last two games as designated hitter. Rutschman’s absence might’ve opened some playing time for Mountcastle, but he suffered a broken toe on his left foot on Saturday and is set to miss extended time on the 60-day injured list.

The team acquired Christian Encarnacion-Strand on Monday from the Reds. He’ll likely join the Orioles in the coming days. The 26-year-old flashed some big power potential in 2023, hitting 13 homers in only 63 games, but has struggled to find playing time over the last two seasons.

It’s a low-cost upside acquisition for the Orioles.Christian Yelich (hamstring)Yelich exited in the fifth inning on Sunday against the Nationals with left hamstring tightness. Manager Pat Murphy said after the game that there would likely be further bad news regarding the 34-year-old veteran. It’s another big blow to a Brewers lineup that is already missing Jackson Chourio and Andrew Vaughn, both sidelined with a fractured hand.

Chourio’s latest imaging showed signs of healing, but he’s not been cleared to hit. A stint on the injured list for Yelich would likely bring Jeferson Quero back from Triple-A Nashville, though he offers very little fantasy appeal.George Springer (toe)Springer suffered a fractured left big toe after fouling a ball off his foot on Saturday against the Twins. Manager John Schneider said Sunday that Springer could just miss the minimum time as he recovers.

So, look for him to return before the end of the month. Meanwhile, the team recalled Eloy Jiménez from Triple-A Buffalo to take Springer’s spot on the active roster. Jiménez started at designated hitter, batting seventh against Minnesota on Sunday. The 29-year-old slugger comes with some pedigree as a former top prospect, but has struggled to stay healthy o
