Payton Tolle is putting pressure on Red Sox's Opening Day roster decision

The Boston Red Sox's Opening Day starting rotation is largely believed to be set — Johan Oviedo has performed well in his first weeks with the organization and he seems to have locked down the fifth spot. Garrett Crochet, Sonny Gray, Ranger Suárez, Brayan Bello and Oviedo are the most likely five players to make the rotation, at least in the early going of the 2026 season.

But Payton Tolle is making Alex Cora's rotation decisions much harder. The 22-year-old isn't expected to begin the 2026 season in the major leagues after his meteoric rise through Boston's minor league system last year, but he's made an excellent case so far this spring.

Tolle has given up three runs on eight hits over 10.2 innings in Grapefruit League play, good for a 2.53 ERA. He's fanned 13 batters and walked just one, and his 0.84 WHIP is impeccable.

His March 17 outing, his longest of spring training so far, turned heads across the league. Tolle tore through the Atlanta Braves' lineup over four scoreless, three-hit innings. He struck five Braves out and didn't walk anyone, but hit a batter.

Payton Tolle's push for the Red Sox's Opening Day roster has been incredible to watch

Tolle has looked particularly deadly this spring because he's bolstered his arsenal to make his already-fearsome fastball perform even better. He's added a curveball to his list of offerings and refined some of his other offspeed pitches to create a major-league ready repertoire. Tolle threw nine curveballs against Atlanta and collected a 50% whiff rate with them. He only threw three sliders, but that also looked great, as hitters whiffed at two of them.

Despite Tolle's improved arsenal and skillful pitching through four spring training appearances, the Red Sox are still likely to send him down to the minor leagues to start the season. Since they had to promote him so quickly, when he was just just 22 years old during their playoff push last season, the Red Sox are focused on maintaining an extra year of service time on his (as well as fellow top prospect Connelly Early's) contract. Tolle will need to spend 46 total days in the minor leagues to maintain a year of service time on his contract, which Boston is likely to prioritize.

If Tolle begins the season in the minor leagues, it won't be because he doesn't deserve a spot in the Red Sox's rotation, but because they want to be strategic. Oviedo has more major league experience than Tolle and he's also improved since last season. No matter when he makes it to the major leagues, Tolle will be a dangerous addition to the Sox's rotation.
