Boston Red Sox Pitchers of the Month - July 2025

Aside from pitchers not named Garrett Crochet, Aroldis Chapman, Brayan Bello, or Garrett Whitlock, the Red Sox’s pitching staff put together a middle-of-the-road performance in July. They threw 130.2 innings (11th) and posted a 3.10 ERA (3rd), 21.1% strikeout rate (18th), and 1.8 fWAR (11th). Here’s an overview of the Red Sox’s best pitching performances this month. While the number one spot remains the same for the fourth consecutive month, there are two new faces featured.

3. Brennan Bernardino

Appearing in 47 games this year, Bernardino has looked overworked at times. Upon first glance, Berandino’s stats don’t scream lights-out reliever, but he deserves recognition for his performance and willingness to take the mound whenever his team needs him. He posted a 0.00 ERA, 2.68 FIP, 21.7% strikeout rate, 10.9% batted ball rate, and 0.3 fWAR across 12.0 innings in July. Despite his up-and-down performance, he is the only Red Sox pitcher who has not given up a single earned run over the past month.  Bernardino also recorded his first career save on July 23rd. For the sake of his health, I hope the Red Sox lean on Steven Matz so he can get some much-needed rest.

2. Garrett Whitlock

Garrett Whitlock is on fire. He posted a 0.96 ERA, 0.20 FIP, 44.4% strikeout rate, 0.0% batted ball rate, and 0.6 fWAR across 9.1 innings in July. His strikeout rate is the highest among Red Sox pitchers over the past month. Whitlock has been sharper than a Japanese steak knife in high-leverage situations, which was a glaring area of weakness earlier in the season. See his 2025 monthly high-leverage situations splits: 

• March/April: 5.40 ERA
• May: 15.00 ERA
• June: 0.00 ERA
• July: 0.00 ERA

In June and July, he hasn’t allowed a single earned run during high-leverage situations. Whitlock could easily slot in as the team’s closer right now, and he might get more opportunities to close games as the season progresses. 

1. Garrett Crochet

Garrett Crochet started in four games, posting a 1.73 ERA, 2.40 FIP, 28.7% strikeout rate, 5.6% batted ball rate, and 0.9 fWAR across 26.0 innings. Whenever he takes the mound, I automatically assume the Red Sox will win. He’s just that good. On July 12, Crochet threw a nine-inning shutout versus the Rays.

Crochet is giving Tarik Skubal a run for his money in the American League Cy Young race.  He leads pitchers in strikeouts (175) and innings pitched (141.1), and ranks third in fWAR (4.5), eighth in FIP (2.53), and 17th in ERA (2.23). If Crochet maintains his performance through the end of the season, BBWAA members will face a tough voting decision come the fall.
