Right-hander JB Bukauskas is suffering from a “significant” lat injury, according to a report from Todd Rosiak of the Milwaukee Journal-Sentinel. According to Rosiak, Bukauskas is currently weighing whether to undergo surgery or attempt to rehab the injury.
It’s a brutal blow for Bukauskas, who was a first-round pick by the Astros in 2017 and a consensus top-100 prospect early in his career. He was a key piece sent to the Diamondbacks as part of the Zack Greinke trade back in 2019 and made his MLB debut back in 2021, though he’s been dogged by injuries ever since. Bukauskas was sidelined for six weeks due to an elbow flexor strain and then missed nearly the entire 2022 campaign due to a teres major strain. The right-hander was designated for assignment by Arizona in January of 2023 but was claimed off waivers by the Mariners in short order, ending his Diamondbacks career with a 7.79 ERA in 21 appearances.
Bukauskas threw just one inning for the Mariners before being designated for assignment once again in April of that same year, and he was plucked off waivers by Milwaukee a few days later. He’s remained a Brewer ever since and has pitched phenomenally for the club in the brief periods of time where he’s been healthy enough to take the mound, with a microscopic 0.75 ERA and an excellent 26.7% strikeout rate. Unfortunately, his big league work has been limited to just 12 innings due to whiplash, a finger tendon issue, and most recently a lat strain that cost him nearly the entire 2024 season. Milwaukee designated him for assignment back in January, but he opted to accept an outright assignment and head to camp with the Brewers as a non-roster invitee.
Now Bukauskas’s lat issues appear to be flaring up once again. It’s possible that the issue is the very same injury that sidelined him during 2024; after all, Bukauskas was believed to be healthy enough that he was sent on a rehab assignment over the summer, but he was recalled from that assignment after just four appearances due to lingering soreness. It’s not clear if the right-hander’s current lat issue is a new one or a similar situation where he was believed to be healthy until he felt something upon arriving in camp, but in any case the injury is now severe enough for Bukauskas to be at least considering surgery.
A timeline for Bukauskas’s return to action likely won’t be clear until he makes a decision on whether or not to go under the knife, but he figures to be out for quite some time either way. Significant lat strains often require a pitcher to be shut down for at least a month or two before they can resume baseball activities, and surgery comes with a much longer timeline. As one example, Tigers right-hander Alex Lange underwent surgery to repair a torn lat in June of last year and remains out of action. Detroit placed him on the 60-day IL earlier this month, suggesting they don’t expect him to be healthy enough to return until the tail end of May at the absolute earliest.
Fortunately for the Brewers, the club has a fairly deep bullpen with plenty of options to help make up for the loss of Bukauskas. Trevor Megill, Joel Payamps, and Nick Mears are among the right-handers towards the top of the club’s depth chart, with players such as Abner Uribe, Grant Anderson, and non-roster veterans like Deivi Garcia and Vinny Nittoli providing further depth behind the club’s top options.
