Boston vs Houston Matchups, Results & Stats

McCullers did exactly what was needed, hurling seven strong innings to lead the Astros to an 8-1 victory in the opener of a three-game home series that continues on Tuesday. Houston needed only two pitchers on Monday to secure the triumph, with reliever Ryan Weiss covering the final two frames of the Astros' third straight win.

Astros manager Joe Espada had an inkling that his starter was up to snuff when McCullers struck out Roman Anthony and Trevor Story to open the game. McCullers faced the minimum through six and, when he ran into a spot of trouble in the seventh, Espada let him finish the job.

"He picked us up big time," Espada said.

"He knew exactly what he needed to do, which makes it even harder to do. The expectations are I need to pick the teammates up. And then he does it against that lineup. It just tells you it's not his first rodeo. He's been in that spot before. The fact that he delivered and picked us up put us in a much better spot for (Tuesday)."

Right-hander Hunter Brown (0-0, 0.00 ERA) has the starting assignment for Houston on Tuesday. He worked 4 2/3 scoreless innings against the Angels but did not factor into the decision of a 3-0 loss last Thursday after he allowed four hits and four walks with nine strikeouts. Brown recorded eight scoreless starts last season.

Brown is 2-0 with a 1.89 ERA across three career starts against the Red Sox. He faced Boston twice in 2025 and allowed two runs on 10 hits and four walks with 10 strikeouts in 13 2/3 innings.

Right-hander Brayan Bello (11-9, 3.35 ERA in 2025) is the scheduled starter for the Red Sox on Tuesday. He logged a career-high 166 2/3 innings last season but labored down the stretch and dropped his last three decisions while allowing nine earned runs across 14 innings. During one stretch in 2025, Bello recorded a decision in 13 consecutive starts, going 8-5 with a 2.49 ERA.

Bello is 1-1 with a 2.19 ERA in three career appearances (two starts) against the Astros. He faced Houston in consecutive starts in late August 2023, splitting the decisions after allowing four runs (three earned) on 13 hits and five walks with six strikeouts across 11 2/3 innings.

After scratching across just 10 runs while dropping a three-game series to the Cincinnati Reds over the weekend, the Red Sox mustered only six baserunners against the Astros on Monday.

The slow start offensively hasn't presented any cause for concern.

"Honestly, I think we're in a pretty good spot," Red Sox outfielder Jarren Duran said. "I feel like we're a pretty positive group. I feel like nobody has really been down on themselves, and we're very talkative. I feel like we've been talking to each other about what we've seen on the mound."
