Veteran reliever Blake Treinen was placed on the 15-day injured list on Saturday due to tightness in his right forearm, and Dodgers manager Dave Roberts shed more light on Treinen’s situation when speaking with the Orange County Register’s Bill Plunkett and other reporters on Sunday. Specifically, Treinen has a “low-grade sprain of the forearm,” as Roberts described it, as some forearm discomfort throughout the week resurfaced Friday when Treinen was warming up to enter the game. “He was one hitter away as he was warming up to go into the game,” Roberts said. “Obviously, if he were to pitch, it could have been potentially worse. So I would say we’re in the dodged-a-bullet category.” An MRI revealed the sprain on Saturday, and Treinen will get more testing done before a recovery timeline is established. Roberts’ view of the injury seemed relatively positive, though even if Treinen has avoided a more long-term problem, it stands to reason that he’ll miss more than just 15 days just out of natural precaution when dealing with forearm-related injuries. Treinen’s first four seasons in Los Angeles yielded excellent (if often injury-plagued) results, leading to a two-year, $22M deal to rejoin the club this past offseason. Treinen was off to a solid start in 2025, if a bit of a step back only in comparison to his past standards since coming to the Dodgers prior to the 2020 season. Over eight innings and eight appearances this year, Treinen has a 3.38 ERA, 27.8% strikeout rate, and 8.3% walk rate. Turning to another Blake on the Dodgers’ injured list, Saturday marked Blake Snell’s first bullpen session since he was placed on the 15-day IL with left shoulder inflammation. Snell told The Athletic’s Fabian Ardaya that he will need at least one more bullpen and simulated game before exploring a rehab assignment, but as for the first step, Snell left his initial bullpen session feeling “way better.” Snell hasn’t pitched since April 2, and it would seem like his IL stint will last over a month, given the number of steps remaining in the recovery process. While the shoulder inflammation doesn’t seem like anything too serious, it does add to Snell’s history of both injuries and first-half struggles. Snell did have a 2.00 ERA in his first two starts and nine innings of the 2025 season, but for his career, he has a 3.95 ERA prior to the All-Star break and then a 2.34 ERA in the second half. The L.A. rotation had another minor injury scare in Sunday's 1-0 win over the Rangers, as Tyler Glasnow left with an apparent leg injury after throwing his first pitch of the fifth inning. Fortunately, the team announced that Glasnow left due to only leg cramps, and Glasnow told MLB.com’s Sonja Chen and other reporters that he believes he’ll be able to make his next start. The Dodgers have off-days on both Monday and Thursday this week, so Glasnow will get a full week before he is next scheduled to take the mound on April 27 against the Pirates.
