◆ Matchup preview
Athletics at Boston Red Sox (2026-08-07). Jack Perkins vs Payton Tolle at Fenway Park.
Starters — Jack Perkins has a 6.72 ERA and 1.40 WHIP across 73.2 innings, with strong bat-missing ability at 10.87 K/9 but shakier run prevention shown by 3.42 BB/9 and 1.71 HR/9. His last three starts were mixed: 5.1 innings and 6 earned runs with 9 strikeouts, then 5.2 innings and 2 earned runs, then 5 innings and 3 earned runs. The recent trend is down. Payton Tolle has a 3.30 ERA and 1.15 WHIP over 101 innings, backed by 9.8 K/9, 2.58 BB/9, and 1.07 HR/9. His last three starts were steady: 6 innings and 2 earned runs with 7 strikeouts, 5.1 innings and 2 earned runs with 7 strikeouts, and 5.2 innings and 4 earned runs with 9 strikeouts. His trend is flat, but the overall profile is stable.
Teams — Oakland enters with a .718 OPS, 498 runs scored, and a .244 team average, which is close to Boston’s offensive output. The bigger issue is on the run prevention side, where the Athletics carry a 5.41 team ERA and 1.49 WHIP, and they are 1-9 over their last 10 games. Boston has a .721 OPS, 504 runs, and a .247 average, giving them a slight edge in overall lineup production. The Red Sox pitching staff has been much sharper, posting a 3.50 team ERA and 1.23 WHIP, and they are 9-1 over their last 10 games. That combination of better current form and stronger staff numbers stands out.
