Arizona Diamondbacks vs Cleveland Guardians Starting Lineup — Friday, Jul 31, 2026

Arizona Diamondbacks at Cleveland Guardians (2026-07-31). Mitch Bratt vs Tanner Bibee at Progressive Field.

Starters — Mitch Bratt has a 6.32 ERA and 1.98 WHIP across 15.2 innings, with 5.74 K/9, 6.32 BB/9, and 2.3 HR/9. His last three starts were 5.0 IP, 5 ER, 3 K, 5 BB; 4.2 IP, 2 ER, 4 K, 1 BB; and 3.0 IP, 3 ER, 0 K, 3 BB. The profile points to command issues and hard-contact risk, especially with the walk rate and home run rate both elevated. Tanner Bibee carries a 3.89 ERA and 1.18 WHIP over 125 innings, with 6.98 K/9, 2.66 BB/9, and 1.44 HR/9. His last three starts were 6.0 IP, 3 ER, 5 K, 2 BB; 6.0 IP, 2 ER, 5 K, 1 BB; and 6.2 IP, 1 ER, 3 K, 4 BB. His recent form has been steadier, and the listed trend is down, supported by just 6 earned runs allowed over those three outings.

Teams — Arizona has the stronger offensive baseline with a .706 OPS, 492 runs, and a .242 team average. The Diamondbacks are also 6-4 over their last 10 games. On the pitching side, Arizona owns a 4.20 team ERA and 1.29 WHIP, which is more middle-of-the-pack than dominant. Cleveland has a .679 OPS, 432 runs, and a .230 team average, so the lineup has been less productive overall. The Guardians are 4-6 in their last 10, but their run prevention has been better than Arizona’s, with a 3.73 team ERA and 1.26 WHIP. That creates a contrast between Arizona’s better offense and Cleveland’s stronger overall pitching numbers.
