Pedro Martinez validates Red Sox’s decision to trust Brayan Bello, praises rotation

For Boston Red Sox fans worried about Brayan Bello after a pair of poor spring training outings, allow Pedro Martinez to ease your concerns.

The Red Sox legend Martinez spoke with MLB.com's Ian Browne in recent days about Boston's current pitching staff, and he predicted a big season from Bello, whom he's mentored for years.

“I think this should be his breakout year," Martinez said of Bello, per Browne. "This should be his coming out party. I think Bello is in perfect shape right now."

Martinez also said that Bello got stronger in the offseason (corroborating other reports about Bello's muscle gain) and that the right-hander should see more velo and overall consistency this year. Martinez was bold enough to call Bello "the hardest worker on the team" after his transformation over the winter.

Red Sox legend Pedro Martinez envisions a breakout season for Brayan Bello

Martinez has made his home in the Dominican Republic a training ground for Bello over multiple winters, so he's had an up-close-and-personal view of Bello's ongoing development.

Bello had a solid 2025, going 11-9 with a 3.35 ERA. Most importantly, he stayed healthy after a late start to the season due to lat tightness, ending up with 28 starts on the year. Bello has now stacked three consecutive seasons of 28 starts or more.

As the Red Sox improved their rotation this offseason and as they sought another power bat to bolster the lineup, Bello's name continually emerged in trade rumors. Having evaded being shipped off for more offense, Bello enters 2026 as a member of a deeper rotation than last year's, potentially taking some pressure off his shoulders.

With Bello widely expected to begin the year as Boston's No. 4 starter behind Garrett Crochet, Ranger Suárez, and Sonny Gray, he's certainly not carrying the burden of being a frontline starter for the Red Sox, although injuries and underperformance from other arms could change that throughout the season.

It's way too early for Red Sox fans to judge Brayan Bello's 2026 potential

If Bello can sustain the durability that's defined his career this far, there's no reason to believe the 26-year-old won't continue developing into a more dominant force. He's still adding to his arsenal of pitches, and as Martinez alluded to, Bello might be just entering his prime years.

Spring training so far hasn't indicated any of this for Bello. His most recent appearance on February 27 yielded three earned runs and four hits allowed in two innings of work. Bello has now allowed nine earned runs in 3 1/3 innings of work this spring over two appearances.

Relax, everyone! It's 3 1/3 innings. If there was ever a time to say, "it's just spring training," now is that time for Bello supporters. Martinez is front and center among these supporters, and Bello has another season in front of him to prove Martinez right. Once the games start to count, we can start adequately judging where Bello's development truly stands.
