June 1, 2026 — When Tanner Bibee took the ball out of the bullpen in the opening series against the Chicago White Sox, few could have imagined that the 27‑year‑old right‑hander would become the first Cleveland pitcher ever to open a season 0‑13. The streak, now the longest winless run to start a campaign in Guardians history, has forced the club’s front office, coaching staff, and fans to reassess a rotation that entered the season with high expectations after a surprise 2025 playoff run.
Who is Tanner Bibee?
Born in San Diego and raised in Rancho Cucamonga, California, Bibee was a third‑round pick of the Cleveland Indians in the 2017 draft. He spent four seasons honing his craft in the minors, where he developed a three‑pitch mix anchored by a mid‑90s four‑seam fastball, a sharp two‑seam cutter, and a changeup that earned him a reputation as a “strikeout‑first” pitcher. In 2022, he broke out with a 3.56 ERA and 12.3 K/9 over 132 innings, earning a spot in the starting rotation for the first time.
His 2023 campaign was a mixed bag: a 9‑9 record, 4.12 ERA, and a career‑high 176 strikeouts, but also 24 home runs allowed, hinting at a vulnerability to power that would later surface. After a solid 2024 where he posted a 3.79 ERA and posted a 1.11 WHIP, Bibee entered 2026 as a key piece of a rotation that also featured veteran left‑hander Shane Bieber, hard‑throwing right‑hander Logan Allen, and the newly acquired free‑agent starter Chris Sale, who signed a two‑year deal in the offseason.
Guardians’ rotation context
The 2025 Guardians surprised the league by clinching the AL Central with a 93‑69 record, largely on the back of a dominant bullpen and a balanced offense that averaged 4.6 runs per game. Their starting staff posted a collective 4.02 ERA, the third‑best in the league. However, the 2026 offseason saw two pivotal changes: the departure of shortstop Isiah Kiner‑Falefa in free agency and the trade of outfielder Steven Kwan for a package of prospects. While the offense still boasts a core of Jose Ramirez and the emerging power of Steven Kwan’s replacement, the lineup’s run production has dipped to 4.1 runs per game, a factor that has amplified the impact of Bibian’s early struggles.
Statistical deep‑dive: why the streak matters
Through 13 starts, Bibee has logged 71.2 innings, striking out 78 batters (9.8 K/9) while walking 27 (3.4 BB/9). His FIP of 4.20 sits modestly below his 4.70 ERA, indicating that fielding and sequencing have contributed to the inflated run total. More striking is his opponent slugging percentage of .452, well above the league average of .398. The 22 home runs he has surrendered translate to 2.8 HR/9, a rate that ranks 27th out of 30 teams for the same span.
Advanced metrics further illuminate the problem. Bibee’s barrel rate against is 11.2% (league average 8.5%), and his hard‑hit rate sits at 42% versus the MLB norm of 38%. Moreover, his BABIP of .340 suggests a blend of bad luck and hard contact, as the league average BABIP for starters is .300. The combination of elevated barrel and hard‑hit rates points to a pitch‑location issue, particularly on the first‑inning fastball count where hitters have been able to square up his 94‑96 mph four‑seamer.

- April 17 vs. Twins – 6.1 IP, 5 ER, 2 HR; 2 runs support, loss 8‑2.
- April 22 vs. Yankees – 4.2 IP, 7 ER, 4 HR; 1 run support, loss 9‑1.
- April 27 vs. Tigers – 5.0 IP, 3 ER, 1 HR; 2 runs support, loss 5‑2.
- May 2 vs. Angels – 6.0 IP, 5 ER, 2 HR; 3 runs support, loss 7‑3.
- May 7 vs. Orioles – 5.1 IP, 4 ER, 2 HR; 1 run support, loss 6‑1.

- June 1 vs. Brewers – 5.1 IP, 4 ER, 2 HR; 2 runs support, loss 6‑2.
In eight of those starts the Guardians scored two runs or fewer, underscoring the dual‑front pressure on Bibee: he must keep the ball in the park while the lineup struggles to generate offense.
Historical comparisons
Before Bibee, the longest winless opening stretch for a Cleveland starter was Steve Sparks’ 0‑9 run in 1999, a season in which the team finished 69‑93. Sparks eventually recorded his first win on June 25, 1999, after a 5‑2 victory over the Detroit Tigers. Bibee’s streak not only eclipses Sparks’ record but also surpasses the infamous 0‑10 start of Dodgers rookie Tyler Anderson in 2014, though Anderson’s ERA was a far more respectable 2.78.
On a league‑wide scale, the last pitcher to begin a season 0‑13 was New York Mets left‑hander Jacob deGrom in 2022, a campaign cut short by injury after 12 starts. DeGrom’s case was an outlier because his underlying peripherals (FIP 2.90, xFIP 2.85) indicated elite performance despite the lack of wins. Bibee’s peripherals, while respectable, do not reach that elite tier, making his streak a genuine concern for Cleveland.
Coaching strategy and adjustments
Manager Stephen Vogt, a former catcher known for his analytical approach, has publicly defended keeping Bibee in the rotation. In a post‑game interview on May 30, Vogt said, “Tanner’s stuff is still there. The issue is sequencing and location. We’re giving him the chance to work through it because we believe in his upside.”
Pitching coach Mike Sarbaugh, who has overseen the development of both Bieber and Allen, outlined a three‑pronged plan: (1) reduce fastball usage in the first two innings to 55% of pitches, (2) increase cutter usage against left‑handed hitters, and (3) introduce a low‑90s split‑finger fastball as an “out‑pitch” in two‑strike counts. The staff also plans to employ more aggressive defensive shifts, especially against right‑handed power hitters who have been barrelled at a rate of 13% against Bibee.
In addition, the Guardians have scheduled a potential “bullpen day” for Bibee’s June 7 start against the Detroit Tigers, a move rarely employed for a pitcher of his experience. This could serve two purposes: preserve his arm while the club evaluates a possible rotation shuffle, and give the bullpen a chance to showcase depth ahead of the trade deadline.
Impact on the playoff picture
The Guardians currently sit third in the AL Central with a 39‑38 record, five games behind the division-leading Minnesota Twins. A continued slump from Bibee threatens to push Cleveland into a wild‑card scramble. With the trade deadline only two months away, the front office faces a dilemma: retain Bibee as a long‑term asset, potentially packaging him in a deal for a veteran arm, or double down on internal development and hope for a mid‑season turnaround.
General manager Chris Antonetti, who guided the 2025 playoff run, told reporters on May 31, “We have a lot of confidence in Tanner. He’s a high‑ upside pitcher who can be a frontline starter for years. But baseball is a business, and if we see a clear path to improve the rotation, we’ll explore it.”
Fantasy implications
Fantasy baseball owners have reacted swiftly. In the past 24 hours, Bibee has been dropped from 68% of active rosters in the major fantasy platforms, while his draft value has plunged from a mid‑round pick in 2025 to a “bench‑only” status. Conversely, pitchers like Texas Rangers’ Andrew Heaney (8.9 K/9, 1.2 HR/9) and Seattle’s Logan Gilbert (10.2 K/9, 0.9 HR/9) have seen a surge in ownership as owners search for reliable strikeout arms with low home‑run susceptibility.
What the next month could look like
If Bibee can lower his HR/9 to league average (≈1.2) and the Guardians’ offense rebounds to at least 4.3 runs per game, statistical models from Fangraphs project a swing in his win probability from 0.30 to 0.55 over the next 10 starts. However, if the home‑run trend continues, his ERA could climb above 5.00, potentially prompting a demotion to the bullpen or a trade.
Veteran left‑hander Shane Bieber, slated to start the weekend series against the Tampa Bay Rays, has taken Bibee under his wing in the clubhouse. “We’ll go over my approach to attacking the zone and using the cutter as a ‘get‑out’ pitch,” Bieber said. “If he can trust his secondary pitches early, the hitters won’t sit on the fastball.”
Conclusion
Tanner Bibee’s 0‑13 start is more than a statistical oddity; it is a symptom of a rotation caught between a potent but inconsistent offense and an inability to contain power. The Guardians’ response—whether through strategic pitch‑mix adjustments, a potential bullpen day, or a mid‑season roster move—will shape not only Bibee’s career trajectory but also Cleveland’s chances of returning to the postseason. As the June grind continues, every home run, every run scored, and every pitch location will be dissected by analysts, coaches, and fantasy owners alike, all watching to see if the historic streak can finally be broken.
How does Bibee’s home‑run rate compare to the league average?
Bibee has allowed 22 homers in 13 starts, roughly 1.7 per nine innings, while the MLB average sits near 1.2 per nine innings (based on June 2026 league stats).
When was the last time a Guardians pitcher had a winless streak longer than 10 games?
The previous longest streak belonged to Steve Sparks, who went 0‑9 in 1999 before finally recording a win.
What adjustments are coaches considering to help Bibee?
Coaches have discussed altering pitch sequencing to reduce early‑game fastball counts and emphasizing off‑speed pitches in high‑leverage spots, aiming to lower opponent barrel rates.
