Athletics vs Arizona Diamondbacks

Athletics at Arizona Diamondbacks (2026-07-20). Jeffrey Springs vs Mitch Bratt at Chase Field.

Starters — Jeffrey Springs has a 6.08 ERA and 1.42 WHIP across 97.2 innings, with 7.74 K/9, 3.41 BB/9, and a high 2.4 HR/9. His last three starts were 4.1 IP, 6 ER, 4 K, 4 BB; 5.1 IP, 6 ER, 2 K, 4 BB; and 5.1 IP, 3 ER, 6 K, 2 BB. The trend is flat, but the recent line still shows damage from walks and home runs. Mitch Bratt has a 6.00 ERA and 1.67 WHIP in a very small 6.0-inning sample, with 4.5 K/9, 7.5 BB/9, and 1.5 HR/9. His last two appearances were 3.0 IP, 3 ER, 0 K, 3 BB and 3.0 IP, 1 ER, 3 K, 2 BB. There is no formal trend listed, but the early profile points to shaky command and limited swing-and-miss.

Teams — Oakland enters with a .728 OPS, 443 runs scored, a .246 team average, and a 5.33 team ERA with a 1.48 WHIP. The Athletics have been cold lately at 1-9 over their last 10, but their offense has still been more productive on the season than Arizona’s by OPS and total runs. Arizona has a .695 OPS, 433 runs scored, and a .237 team average, but the overall pitching staff has been clearly better with a 4.21 ERA and 1.28 WHIP. The Diamondbacks also bring stronger current form at 7-3 in their last 10, which matters given the gap in bullpen and staff-level run prevention.
