◆ Matchup preview

Arizona Diamondbacks at Pittsburgh Pirates (2026-07-28). Brandon Pfaadt vs Bubba Chandler at PNC Park.

Starters — Pfaadt has a 4.43 ERA, 1.32 WHIP, and 65.0 innings with 6.23 K/9, 2.77 BB/9, and 1.11 HR/9. His last three starts were steady: 6.0 IP, 2 ER, 1 K, 2 BB; 5.1 IP, 2 ER, 3 K, 0 BB; and 5.1 IP, 2 ER, 2 K, 0 BB. The recent trend is up, driven by run prevention and improved control, though the strikeout rate remains modest. Chandler carries a 4.47 ERA, 1.39 WHIP, and 100.2 innings with 8.05 K/9, 5.01 BB/9, and 0.89 HR/9. His last three starts were 6.1 IP, 0 ER, 5 K, 1 BB; 4.2 IP, 2 ER, 6 K, 3 BB; and 4.0 IP, 4 ER, 0 K, 4 BB. The trend is down overall despite the strong most recent outing, with command volatility still the key issue.

Teams — Arizona owns a .706 OPS and 481 runs scored, with a .241 team average. The Diamondbacks pitching staff has a 4.23 ERA and 1.30 WHIP, and they are 6-4 over their last 10 games. Pittsburgh has been the better offensive club by the numbers, posting a .758 OPS, 556 runs, and a .260 team average. The Pirates staff sits at a 4.30 ERA and 1.31 WHIP, and they are 5-5 in their last 10. This matchup pairs a slightly cleaner Arizona pitching profile against a more productive Pittsburgh lineup.
