Red Sox rotation preview: Crochet, Suarez lead elite group for 2026 originally appeared on NBC Sports Boston
If the Boston Red Sox return to the postseason in 2026, their pitching staff will lead the way.
Boston revamped its starting rotation with significant upgrades this offseason. After acquiring right-handers Johan Oviedo and Sonny Gray in trades with the Pittsburgh Pirates and St. Louis Cardinals, the Red Sox signed one of the top free-agent starters in ex-Philadelphia Phillies left-hander Ranger Suarez.
Suarez will form a strong 1-2 punch with 2025 American League Cy Young runner-up Garrett Crochet. Oviedo and Gray, alongside returnee Brayan Bello, are expected to shore up a rotation that is projected to be among baseball’s best.
Red Sox chief baseball officer Craig Breslow believes run prevention will be the club’s key to success this upcoming season.
“I don’t think there’s a question anymore that the identity of our team and the strength of our team is going to be our pitching and our ability to prevent runs,” Breslow said last month, per MassLive.com.
“I think the improvements we made on the pitching side are significant,” he added. “It can be difficult at times to fully appreciate the impact of having dominant starting pitching. But going into a game feeling like we can just play our game offensively and on the bases because our pitching is going to keep us in the game is such a huge advantage for the team. I think no matter who we’re playing on any given day, we’re going to feel like we’ve got a chance to win.”
Beyond their projected five-man rotation, the Red Sox have a handful of depth pieces who can step up if injuries become a factor. Here’s a closer look at Boston’s starting pitchers for the 2026 campaign:
1. Garrett Crochet, LHP
2025 stats: 18-5, 2.59 ERA, 1.028 WHIP, 255 SO, 46 BB, 205.1 IP (32 starts)
“He’ll start in Cincinnati for Game 1. Let’s get that (expletive) over with,” manager Alex Cora said of Crochet last week at Fort Myers.
Cora stated the obvious, as there was never any doubt that Crochet would get the Opening Day nod. The 26-year-old southpaw arrived in Boston last offseason with lofty expectations and exceeded them, establishing himself as the club’s unquestioned ace and finishing his first year with the team as the American League Cy Young runner-up.
Crochet led the majors in strikeouts (255) while pacing the AL in innings pitched (205.1) and SO/9 (11.2). If there’s one part of his game he could improve on in 2026, it’s the home runs allowed. He let up a career-high 24 long balls last season.
One interesting development could make Crochet even more dominant in 2026. According to Tim Healey of The Boston Globe, Crochet’s changeup (used only 4 percent of the time last season) is now more of a splitter because of a new grip he learned over the offseason. If he turns that into another putaway pitch, it isn’t far-fetched to say he could be the first pitcher since Justin Verlander in 2019 to join the 300-strikeout club.
Chris Sale (308 in 2017) was the last Sox pitcher to notch 300 Ks in a single season.
2. Ranger Suarez, LHP
2025 stats: 12-8, 3.20 ERA, 1.22 WHIP, 151 SO, 38 BB, 157.1IP (26 starts)
The Red Sox signed Suarez to a five-year, $130 million contract in January, officially ending the 30-year-old’s eight-year tenure with the Philadelphia Phillies. The move solidified Boston’s rotation as one of MLB’s best heading into 2026.
While Suarez and Crochet are both left-handed, that’s where the similarities between the two end. Suarez isn’t going to wow anyone with his fastball, which sits in the low 90s. He also isn’t going to strike a ton of guys out, as he tallied 151 strikeouts in 157.1 innings (8.6 SO/9) and ranked in the 24th percentile in K rate last season.
Where Suarez excels is in limiting hard contact. He ranked in the 95th percentile in average exit velocity (86.5) and 98th percentile in hard-hit percentage (31.1) in 2025. He induced ground balls 48 percent of the time (76th percentile).
Suarez also doesn’t walk many batters. His walk totals have decreased each season since he converted to a full-time starter in 2022.
As a ground-ball pitcher, Suarez will need the Red Sox’ infield defense to be more consistent in 2026. Boston made moves to improve in that department by trading for first baseman Willson Contreras and second baseman/third baseman Caleb Durbin. Former top prospect Marcelo Mayer should also provide a defensive upgrade after impressing at second and third base last season.
3. Sonny Gray, RHP
2025 stats: 14-8, 4.28 ERA, 1.234 WHIP, 201 SO, 38 BB, 180.2 IP (32 starts)
Boston traded right-hander Richard Fitts and left-handed prospect Brandon Clarke to the Cardinals in exchange for Gray in November. It was a surprising deal at the time, but it makes more sense now that the veteran righty won’t be relied on to be the club’s No. 2 starter.
Gray’s track record speaks for itself. The 36-year-old is a three-time All-Star who finished as the AL Cy Young runner-up with the Minnesota Twins in 2023. While his 2025 numbers indicate a possible decline, a closer look under the hood shows he still has plenty left in the tank heading into Year 14 of his career.
Gray’s FIP last season was a respectable 3.39, so his bloated 4.28 ERA can largely be chalked up to bad luck. He had the fourth-largest FIP/ERA gap among qualified right-handed starters in 2025.
Gray also tallied 201 strikeouts with only 38 walks over 32 starts last season, giving him the best strikeout-to-walk ratio in the National League and the fourth-best in MLB, trailing only Tarik Skubal, Crochet, and Bryan Woo.
Those expecting Gray to show his age in 2026 will likely be pleasantly surprised. There aren’t many better No. 3 starters in the game.
4. Brayan Bello, RHP
2025 stats: 11-9, 3.35 ERA, 1.236 WHIP, 124 SO, 59 BB, 166.2 IP (29 games, 28 starts)
Brayan Bello stepped up as a solid No. 2 Red Sox starter last season — the most productive of the 26-year-old’s young career. He’ll look to build off that success with less pressure on him to do so as Boston’s No. 4.
Bello should benefit from Suarez’s presence in 2026. Both pitchers rely on inducing ground balls and soft contact to get outs. According to Lauren Campbell of MassLive.com, Bello has been working with Suarez in Fort Myers on his curveball and a new grip for his changeup. Improvements to those pitches could help Bello take another step forward next season, as he has relied heavily on his sinker and sweeper.
If Bello can pick up where he left off in the second half of 2025, it’ll help the Red Sox’ rotation establish itself as arguably MLB’s best. From mid-June through August, he posted a 2.42 ERA while striking out 71 batters and walking 22 over 14 starts.
5. Johan Oviedo, RHP
2025 stats: 2-1, 3.57 ERA, 1.215 WHIP, 42 SO, 23 BB, 40.1 IP (nine starts)
Oviedo is the frontrunner for the No. 5 spot in the rotation after arriving via a December trade with the Pirates. The soon-to-be 28-year-old is a bit of a wild card heading into his first full season post-Tommy John surgery, but he offers high upside with elite extension, an upper-90s fastball, and a wipeout slider.
Last season with Pittsburgh, Oviedo allowed more than two earned runs only once over his first nine starts back from injury. In 2023, his last full season, he had a 4.31 ERA and 1.373 WHIP with 158 strikeouts in 32 starts.
The biggest concern with Oviedo is his command. He had 5.1 walks per nine innings in 2025 and 4.2 BB/9 in 2023, when he also had an NL-leading 13 hit-by-pitches.
If his command improves, Oviedo should emerge as a rock-solid No. 5 for Boston next season. If control remains an issue, he’ll likely revert to a bullpen role while one of the following options takes over as the club’s No. 5 starter.
Other options: Patrick Sandoval, Kutter Crawford, Payton Tolle, Connelly Early
The Red Sox parted ways with a handful of pitching depth options in offseason trades, so it’s down to four starters who will compete with Oviedo for a spot in the rotation.
Patrick Sandoval is working his way back from Tommy John surgery, which forced him to miss all of 2025. The left-hander had flashes of brilliance during his time with the Los Angeles Angels, but he seems like a long shot to begin 2026 in Boston’s rotation. Assuming he’s healthy, he’d fit well in a Red Sox bullpen that lacks left-handed arms.
Kutter Crawford also missed the entire 2025 campaign with knee and wrist issues. He was solid as a starter for Boston in 2023 and 2024, but he seems more fit for a bullpen/spot-starter role this upcoming season.
Oviedo’s biggest competition for the No. 5 slot could be the team’s top two pitching prospects, Payton Tolle and Connelly Early. Tolle, a left-handed power arm, started 2025 in Single-A and finished the year with the big-league club. Although he experienced growing pains in the majors, he still has the stuff to be a key contributor at some point this year, even if he doesn’t make the Opening Day roster.
While Tolle struggled to find his footing in the majors, Early thrived. He posted a 2.33 ERA across his first four MLB starts and was given the starting nod for Game 3 of the Wild Card Series vs. the New York Yankees. He earned the loss in that one, but the fact that he was counted on in the biggest game of the year shows that the club is already supremely confident in the 23-year-old.
Of the four depth options, Early seems like the most likely candidate to edge out Oviedo for a spot in the rotation.
