BOSTON — The Red Sox are steadily progressing towards a fully fit pitching lineup. On Monday, Red Sox manager Alex Cora confirmed that right-hander Brayan Bello is set to make his season debut against the Seattle Mariners on Tuesday.

Bello is the first of two players expected to join, with Lucas Giolito, who completed his fourth rehab start on Sunday, also nearing a return. “It’s beneficial,” Cora stated. “We’ve been short two pitchers, and the rest have stepped up well.

However, he’s crucial for our goals.” Bello was sidelined with right shoulder inflammation during spring training, prompting the Red Sox to ease him back. Cora aims for Bello to pitch five innings in his initial start, ensuring he isn’t overexerted. “His speed has increased, which is critical for us. His pitch dynamics are impressive. We know his potential,” Cora added. “I’m thrilled about him.”

Bello started 30 games in 2024, pitching a career-best 162 1/3 innings. After being Boston’s Opening Day starter, Bello rebounded from early difficulties and excelled in the latter half of the season (3.66 ERA post-July 1).

“I believe he gained significant insights throughout the year,” mentioned Cora, highlighting Bello’s improved use of the four-seamer. “He mastered its usage. Adjusted speeds. Velocity was strong. Completing 30 starts was vital for him. Now he comprehends.

Go out there and pitch.” Cora confirmed lefty Sean Newcomb will take the mound on Wednesday, with Garrett Crochet concluding the series on Thursday. Bello’s return, alongside Giolito’s anticipated comeback, positions the Red Sox close to a starting rotation featuring Crochet, Walker Buehler, Tanner Houck, Bello, and Giolito.
