San Diego Padres vs Arizona Diamondbacks

San Diego Padres at Arizona Diamondbacks (2026-08-05). Casey Mize vs Mitch Bratt at Chase Field.

Starters — Casey Mize has been the steadier profile by a wide margin, carrying a 2.70 ERA and 0.99 WHIP across 86.2 innings with 8.83 K/9, 1.97 BB/9, and 0.52 HR/9. He has allowed only 5 homers all season. In his last three starts, he went 6.0 IP with 1 ER and 0 BB, then 3.1 IP with 1 ER, then 5.2 IP with 3 ER. The listed trend is down, but the full body of work still shows strong run prevention and command. Mitch Bratt enters with a 5.23 ERA and 1.84 WHIP in 20.2 innings, with 5.23 K/9, 6.53 BB/9, and 1.74 HR/9. His last three starts were 5.0 IP with 1 ER and 4 BB, 5.0 IP with 5 ER and 5 BB, and 4.2 IP with 2 ER and 1 BB. The trend is flat, and the key issue remains traffic on the bases from walks and contact quality.

Teams — San Diego owns a .696 OPS, 482 runs, and a .236 average, but the recent form stands out at 8-2 over the last 10 games. The Padres’ pitching staff has a 4.15 ERA and 1.32 WHIP, which is solid enough to support lower-scoring scripts when the starter is efficient. Arizona has a slightly better offensive baseline with a .706 OPS, 517 runs, and a .241 average. The Diamondbacks are 5-5 in their last 10. Their staff numbers are close to San Diego’s overall at a 4.20 ERA and 1.30 WHIP, but this matchup puts more pressure on the home bullpen if Bratt’s control issues shorten his outing.
