Guardians open to offers on Shane Bieber

The Guardians have made rehabbing right-hander Shane Bieber available, reports Jeff Passan of ESPN. The 2020 AL Cy Young winner has yet to pitch in the majors this season after undergoing Tommy John surgery last April but is currently on a minor league rehab assignment.

Bieber, 30, signed a two-year, $26MM contract to remain with Cleveland after that ill-timed injury. He can opt out of the contract at season’s end, which only further muddies a complicated trade scenario. Bieber is owed the balance of a $10MM salary and at least a $4MM buyout on a $16MM player option for the upcoming season.

Cleveland had hoped that Bieber would be back on a big league mound by now. He originally embarked on a minor league rehab assignment on May 31 but felt some soreness that caused the Guards to pull him from that rehab stint and slow his return process. That initial soreness didn’t prove to be any kind of significant recurrence of injury, as Bieber’s now back on the mound. He made the second start of his current rehab stint last night with High-A Lake County. He’s pitched five innings and held opponents to a run with a 9-to-1 K/BB ratio on this rehab stint. Bieber also tossed 2 1/3 shutout innings with five strikeouts back in that May 31 appearance.

Bieber made only two starts in 2024, his final season of club control in Cleveland, before incurring his injury. He tossed 12 shutout innings and struck out a comical 20 of his 45 opponents (44.4%) against just one walk (2.2%). Fifty percent of the balls put in play against him were grounders. Also encouraging was the fact that his average fastball had ticked back up to 92 mph after sitting 91.3 mph in each of the past two seasons. His heater had been particularly limited in April in the 2022-23 seasons, sitting under 91 mph in both. That made the velo uptick all the more encouraging. It was a sample of just two starts, but it’s hard to draw up a better beginning to a pitcher’s walk year — or a worse finish than what quickly transpired thereafter.

It’s hard to know what to expect from Bieber at this point. Scouts figure to keep a particularly close eye on his remaining rehab starts as a result. Not only is Bieber recovering from Tommy John surgery, he’d pitched with diminished results in 2023 due to elbow troubles. He tossed 128 innings in 2023 and logged a 3.80 ERA with a career-low 20.1% strikeout rate.

At his best, Bieber is a frontline starter capable of dominating any lineup in baseball. From 2020-22, he pitched 374 innings with a 2.70 ERA, a 30.4% strikeout rate, a 6% walk rate and a 47.2% ground-ball rate. Those rate stats all range from good to excellent, and fielding-independent metrics were similarly bullish on Bieber’s success (2.75 FIP, 3.04 SIERA). He looked like more of a third or fourth starter in 2023 while working with career-low velocity, and now he’s coming off a major surgery with at least one minor setback. He’s an enigma, to say the least.

The player option for the 2026 season makes him all the more difficult to value. If Bieber is activated within the next two to three weeks and pitches even competently down the stretch, he’s sure to decline a net $12MM player option in favor of a return to free agency. If he pitches poorly and/or encounters further injury woes, he’d likely pick up that player option and stick his new club with a $16MM salary it’d prefer not to have on the books.

Given all those layers, the Guardians may not extract the sort of return that would typically be commensurate with a brand-name pitcher of this caliber. Bieber stands as a high-upside play but one who comes with plenty of risk as well. A trade shouldn’t be seen as a given, particularly not with Cleveland riding a three-game win streak that’s put them back to .500 and within 2.5 games of a Wild Card spot in the American League. But Bieber’s next rehab outing and the Guardians’ play in the next week merit a watchful eye, as a healthy Bieber could be a major boon for a contender’s staff — whether that’s the Guardians themselves or a theoretical trade partner.
