The Boston Red Sox’s Pitching Depth: A New Era of Strength

With the acquisition of Ranger Suárez, the Boston Red Sox have built what could be the most formidable rotation in the American League. Their pitching depth is now arguably among the best in all of Major League Baseball. This strength comes from a potential starting five that includes Garrett Crochet, Suárez, Sonny Gray, Brayan Bello, and Johan Oviedo. This group has shifted the team’s focus toward run prevention, setting the stage for a strong 2026 season.

Adding Kyle Harrison and a fully healthy Kutter Crawford and Patrick Sandoval to this mix gives the Red Sox an even deeper rotation than they had in 2025. This depth extends beyond the major league roster, with players on the 40-man roster in Worcester ready to step in if needed. Connelly Early and Payton Tolle were key additions during the stretch run, but they may begin the season in Triple-A.

The Dual Aces

Last offseason, the Red Sox made a bold move by acquiring Garrett Crochet from the Chicago White Sox, aiming to make him their ace. In his first full season with Boston, Crochet delivered. He started 32 games and finished with an 18-5 record, posting a 2.59 ERA. His performance was highlighted by 205 1/3 innings pitched and 255 strikeouts, breaking his career high for both innings and strikeouts.

Despite a second-half ERA of 3.20 in 76 innings—where he allowed 14 home runs—Crochet remained committed to the team. He rarely had starts pushed back, showing his dedication during a crucial playoff race. Now, he’s joined by Suárez, who can help share the workload. Although Suárez hasn’t completed a full season yet, his numbers are impressive. Over 119 starts, he has a 42-32 record with a 3.45 ERA in 666 innings. He struck out 619 batters while walking just 209, and allowed only 60 home runs.

The Other New Guys

Chief Baseball Officer Craig Breslow has been active in the trade market, bringing in both Sonny Gray and Johan Oviedo before the Winter Meetings. These moves were aimed at strengthening the Red Sox rotation after a season filled with multiple options. Gray, acquired from St. Louis, brought immediate impact despite a 4.28 ERA in 180 2/3 innings. He struck out 201 batters and showed promise with a 31.2% chase rate and a 27.5% whiff rate.

Oviedo, returning from injury, showed flashes of potential. Limited to nine starts, he tossed 40 1/3 innings with 42 strikeouts. While his walk rate was higher at 13.5%, his strikeout rate of 24.7% and a 29% whiff rate indicated his ability to limit hard contact.

The Back End

The fifth starter spot remains uncertain, with health, spring training performance, and potential trades all factors. If the season started today, Brayan Bello would likely take the role due to his 2025 performance. However, both Kutter Crawford and Patrick Sandoval, who missed most of 2025, could also compete for the spot.

Kyle Harrison, part of the Rafael Devers trade, has shown promise but still needs development. Meanwhile, young pitchers like Connelly Early and Payton Tolle will likely start the season in Worcester. The addition of Tyler Uberstine, Shane Drohan, and David Sandlin to the 40-man roster adds more depth, with plans to use them as starters or relievers depending on their development.

The Young Guys

Despite some promising moments, Early and Tolle still need improvement. They may begin the season in Worcester to refine their skills. Among the new additions, Sandlin stands out as the most intriguing. Initially developed as a starter, he struggled in relief last season. With his talent, it’s likely the Red Sox will experiment with him as a starter again in 2026.

The Last Word

The Red Sox are in a much stronger position for pitching depth than they were entering 2025. While injuries and inconsistency affected their depth last year, the current roster offers more flexibility. With a deep rotation and talented minor league prospects, the team is well-prepared for the challenges ahead. As spring training approaches, the Red Sox are poised for a successful 2026 season.
