Mariners Outright J.B. Bukauskas

The Mariners announced that reliever J.B. Bukauskas has gone unclaimed on waivers. He’s been sent outright to Triple-A Tacoma and will be in big league camp as a non-roster Spring Training invitee.

Bukauskas didn’t have a particularly long stay on the Seattle 40-man roster. Claimed off waivers from the Diamondbacks on January 17, he lost his spot earlier this week when the M’s grabbed Tayler Saucedo from the Mets. Seattle quickly ran Bukauskas through waivers and will now be able to retain a former first-round draftee and highly-regarded prospect without allocating a 40-man spot.

The 26-year-old was the 15th overall pick in the 2017 draft by the Astros. Houston flipped the UNC product to Arizona two summers later as part of a four-player package for Zack Greinke. A starter early in his minor league days, Bukauskas has come with questions about his ability to hold up in a rotation because of inconsistent command dating back to college. Those concerns have borne out over the past two seasons, as the Snakes moved him to relief after adding him to the roster over the 2020-21 offseason.

Bukauskas made his MLB debut in April ’21, eventually getting into 21 contests. He was hit hard for 19 runs through his first 17 1/3 big league innings despite averaging 94.5 MPH on his fastball and generating plenty of whiffs on his mid-80s slider. An elbow strain cost him a chunk of that season, and a lat injury suffered in Spring Training sidelined him for the first half of last year.

While he didn’t return to the mound until July, Bukauskas closed out the 2022 season with a nice run at Triple-A Reno. Pitching in an extraordinarily hitter-friendly park, he posted a 2.66 ERA with a solid 23.8% strikeout percentage and an excellent 5% walk rate. Nevertheless, he never got another MLB opportunity in a below-average Arizona bullpen and has found himself squeezed off two clubs’ rosters in a matter of weeks.

Bukauskas will try to pitch his way back onto the radar in spring camp and, if necessary, with Tacoma to open next season. The M’s already have a strong bullpen, with Andrés Muñoz, Paul Sewald, Diego Castillo, Matt Brash, Trevor Gott and likely Penn Murfee penciled into jobs. Matt Festa is out of minor league option years and has a strong case to hold onto a roster spot, while whomever of Marco Gonzales and Chris Flexen doesn’t win the #5 starter role could be in the bullpen. The M’s would also have to carry Rule 5 draftee Chris Clarke on the active roster or waive him and, if he clears, send him back to the Cubs. Bukauskas joins Taylor Williams, Casey Sadler, Riley O’Brien and Kyle Tyler among the non-roster depth options in the organization.
