Detroit Tigers at Chicago Cubs (2026-07-20). Jack Flaherty vs Jameson Taillon at Wrigley Field.
Starters — Flaherty carries a 4.48 ERA and 1.41 WHIP over 82.1 innings, with strong bat-missing ability at 10.71 K/9. The risk points are his 4.37 BB/9 and occasional traffic, though he has limited damage to 0.98 HR/9. His last three starts were sharp: 6.0 IP, 2 ER, 6 K, 3 BB; 5.2 IP, 0 ER, 5 K, 0 BB; and 5.0 IP, 0 ER, 9 K, 3 BB. The recent form points to a downward trend in run prevention. Taillon enters with a 5.19 ERA and 1.30 WHIP across 67.2 innings. His 7.85 K/9 and 3.06 BB/9 are more moderate, but the major concern is the 2.66 HR/9, with 20 home runs allowed already. His last three appearances were 1.0 IP, 1 ER, 2 K, 2 BB; 6.1 IP, 2 ER, 6 K, 1 BB; and 5.0 IP, 4 ER, 4 K, 2 BB. His trend is also down, but the home-run rate remains the key volatility factor.
Teams — Detroit has a .710 OPS and 418 runs, with a .234 team average. The Tigers’ edge comes more from run prevention, as their staff owns a 3.58 ERA and 1.21 WHIP. They are also 7-3 over their last 10, which supports the idea that they are getting enough offense behind quality pitching. Chicago brings the stronger lineup profile with a .749 OPS, 502 runs, and a .245 average. The Cubs’ pitching staff has been less steady at a 4.27 ERA and 1.27 WHIP, but they are also 7-3 in their last 10. This matchup sets up as Detroit’s cleaner overall pitching profile against Chicago’s more productive offense.
