Boston Red Sox at Athletics (2026-07-30). Sonny Gray vs Mason Barnett at Sutter Health Park.

Starters — Sonny Gray has a 2.78 ERA and 1.16 WHIP across 106.2 innings, with 7.85 K/9, 2.36 BB/9, and 1.01 HR/9. His last three starts were 5.0 IP/5 ER/3 K/0 BB, 6.0 IP/1 ER/5 K/4 BB, and 6.0 IP/1 ER/3 K/1 BB. The overall form is still strong, but the most recent outing was a clear step back after two efficient starts. Mason Barnett has a 4.74 ERA and 1.38 WHIP in 24.2 innings, with 8.39 K/9, 4.74 BB/9, and 1.82 HR/9. His last three appearances were 3.1 IP/2 ER/2 K/1 BB, 1.0 IP/3 ER/0 K/1 BB, and 1.0 IP/0 ER/0 K/2 BB. The strikeout rate is playable, but the walk rate and home run damage point to volatility, and the trend is up.

Teams — Boston enters with a .708 OPS, 449 runs scored, a .244 team average, and a 3.54 team ERA with a 1.22 WHIP. The Red Sox are 7-3 over their last 10, and the profile is balanced: solid enough offensively and clearly stronger on the mound. The Athletics have a .725 OPS, 476 runs scored, a .245 team average, and a 5.28 team ERA with a 1.48 WHIP. They are 3-7 in their last 10. Oakland has been slightly better than Boston by OPS and runs, but the pitching staff has been a major weakness, especially in run prevention and traffic allowed.
