26-Year-Old PitcherSP
Cleveland Guardians
2025 Fantasy Outlook
Cleveland has a track record of developing pitchers and getting the most out of them, and Bibee looked to be on that path heading into 2024. The final numbers were good, as he improved his strikeout rate along with being one of just 14 pitchers (min 150 IP) with a K-BB percentage greater than 20. He also allowed two or fewer earned runs in 20 of his 31 starts. Yet, it is tough to overlook just how hittable his fastball was in 2024, as the league hit .282 off the pitch (.288 xBA) while hitting .235 or lower off the rest of his offerings. That blueprint makes it possible for teams to have success against him when they are disciplined enough with their approach. Bibee also allowed four or more earned runs eight different times in 2024, including four times against division foes, and half the homers came off that aforementioned fastball. Bibee will carry a price tag tax of "staff ace" with his results to date and expected growth in his third full season at the big league level, but in order for that path to become actualized, Bibee needs his fastball to step up to the plate in a big way in 2025.

Saddled with 11th loss
PCleveland Guardians
August 31, 2025
Bibee (9-11) conceded four runs on six hits and two walks over 6.1 innings to take the loss Sunday against the Mariners. He struck out four.
Analysis
The Cleveland right-hander's recent second-half struggles continued in this 91-pitch performance. Bibee allowed four or more runs for the eighth straight appearance, as he's pitched to a 5.91 ERA, 1.49 WHIP and 31:16 K:BB in 45.2 innings across that span. The 26-year-old looked solid through his first six frames but was chased in the seventh after permitting two of the first three batters to reach, both of which subsequently scored on a hit given up by reliever Matt Festa. Bibee will carry a 4.77 ERA, 1.32 WHIP and 7.9 K/9 over 154.2 total innings into his next matchup, which currently lines up to be at Tampa Bay next weekend.

Past Fantasy Outlooks
2024
2023
Yet another product of the Guardians' pitching factory, Bibee burst onto the prospect radar in 2022 and followed up with a 2.98 ERA, 1.18 WHIP and 141:45 K:BB across 142 innings (25 starts) in his first taste of the majors last season. He began 2023 at Triple-A Columbus but was up with Cleveland by late April, and he was impressive before hip inflammation ended his season in mid-September. A 3.66 xERA and 4.22 xFIP indicate some regression could be on the horizon, especially given he stranded a likely unsustainable 80.0 percent of baserunners (that figure would rank fourth in MLB for qualified starters). Still, the performance of the young right-hander as a rookie can't be overstated, and he should be able to improve his approach in his sophomore campaign. An equal or better effort in 2024 wouldn't be surprising in his age-24 season, especially with the Guardians' track record of building up and maintaining pitching prospects.
A fifth-round pick out of Cal State Fullerton in 2021 who signed for just under $260K, Bibee went from unranked and unheralded to one of the top-30 pitching prospects in the minors after a breakout 2022 season. The 6-foot-2, 205-pound righty registered a 31.6 K-BB% at High-A and a 23.5 K-BB% at Double-A while building up to 132.2 innings. He has a complete four-pitch mix, headlined by a mid-90s fastball and a mid-80s slider. Bibee is a flyball pitcher and he probably got lucky with a 4.8% HR/FB in 73.2 innings at Double-A, but he limited the free passes at both stops. The Guardians' rotation is pretty crowded, and Bibee is unlikely to be as dominant going forward as he was in 2022, so it's not a bad idea to explore his trade value this offseason if you were fortunate enough to add him in-season.
