Austin Peterson didn’t pitch in a high-leverage spot when he finished the Guardians’ season on Sept. 27. He took the final five innings of a 3-2 loss to the Royals, working through what were basically the least meaningful innings Cleveland played all year after the club had already wrapped up the American League Central title and secured a bye for the Wild Card Series.
Still, those innings mattered in a different way. Peterson helped protect the Guardians’ bullpen heading into October, and he left enough of a mark to keep his name in the conversation for 2027.
That may sound like a stretch for a pitcher who posted a 4.41 ERA at Triple-A last season, but the number doesn’t tell the whole story. Peterson had to fight through a triceps strain from spring training, and he also looked sharp in the two big league outings he got with Cleveland. A season earlier, he had turned in a 3.21 ERA over 145 2/3 innings across Double-A and Triple-A.
Most of Peterson’s minor league work has come as a starter, and that’s the clearest route for him to carve out a role with the Guardians. The top of the rotation already has some stability, with Gavin Williams, Parker Messick and potentially Tanner Bibee locked into the first three spots.
After that, things get murkier. Joey Cantillo showed flashes, but he finished the season working behind an opener, while Slade Cecconi ended the year in the bullpen.
That leaves a door open, and Peterson fits the profile of someone who could walk through it. His fastball isn’t overpowering - it averaged 92.4 miles per hour - but the ball seems to get on hitters quicker because of his elite extension. In his brief time in the majors, he backed that up with a 29.6% strikeout rate and a 52.9% groundball rate.
There’s also a possible bullpen path if the rotation doesn’t open up for him. The Guardians needed a steady longman last season, and that job never really settled.
Kolby Allard was expected to handle it after a productive 2025, but he managed just four ineffective appearances before being designated for assignment. Colin Holderman, Matt Festa and Cecconi all took turns in that role at different points, but none of them locked it down.
Peterson remains unproven, but Cleveland has seen pitchers break through before they were established names. Shane Bieber and Parker Messick both got their chances before becoming what they are now. Peterson might be next.

Austin Hedges Just Gave Cleveland Fans A Reason To Worry
Austin Hedges gave Cleveland plenty to think about with his best offensive season in 2026, a timely reminder that he still has something left to offer at the plate as he heads toward free agency. The veteran catcher has long been valued for his defense and presence behind the plate, but this year added another layer to his case as he moved closer to the market with his future still unsettled.
The Guardians will have some internal options if Hedges decides to explore other opportunities, with Kody Huff and Cooper Ingle among the names that could factor into the picture. Even so, once the free agency period opens on November 2, Cleveland may have to contend with the possibility that a player who fits so many of their needs could be looking elsewhere. [Read more 🡒]
Stephen Vogt Rumor Leaves A New Question About His Guardians Future
Stephen Vogt has at least cleared up one bit of offseason uncertainty, saying he intends to stay with the Guardians rather than chase the Mariners managerial opening. The situation briefly created a ripple around Cleveland because reports suggested the club would have been open to letting him explore the possibility, even though Seattle never formally asked about his availability.
Vogts decision keeps him tied to Cleveland on a multiyear contract after back-to-back Manager of the Year seasons in 2024 and 2025, and it removes a potential distraction for a team that would rather keep its momentum intact. Still, the buzz around the Mariners job served as a reminder of how quickly things can shift around a successful manager, even when the most immediate answer is to stay put. [Read more 🡒]
Guardians Fans May Hate What This New 2027 Outlook Suggests
The Guardians are coming off a season that ended with a trip to the AL Championship Series and a painful loss after they had taken a 2-1 series lead, so there is still plenty of proof this group can get back into October and make noise once it gets there. Even so, one recent outlook from Bleacher Report sees Cleveland as a playoff team again in 2027, only in a more modest spot as a wild-card entry rather than a division winner.
For a fan base that just watched a deep run slip away, the bigger concern is what comes next and whether the front office can keep the roster pointed in the right direction through a murky stretch. The Guardians already have offseason questions hanging over their payroll choices and roster moves, and with an impending lockout adding more uncertainty, the long view may be a lot less comforting than the recent results suggest.
