Seattle Mariners at Texas Rangers (2026-07-27). George Kirby vs Kumar Rocker at Globe Life Field.
Starters — Kirby: 3.57 ERA, 1.28 WHIP, 116 IP, 8.07 K/9, 1.94 BB/9, 0.85 HR/9. His last three starts were strong: 6.0 IP, 0 ER, 6 K, 1 BB; 6.0 IP, 2 ER, 7 K, 0 BB; and 8.0 IP, 2 ER, 7 K, 1 BB. The trend is down, which aligns with the recent run prevention and elite walk control. Rocker: 4.13 ERA, 1.31 WHIP, 96 IP, 8.06 K/9, 3.38 BB/9, 1.13 HR/9. His last three starts were 6.0 IP, 0 ER, 6 K, 2 BB; 5.2 IP, 7 ER, 6 K, 2 BB; and 4.1 IP, 3 ER, 4 K, 1 BB. The trend is up, but his profile still carries more traffic risk than Kirby because the walk rate and home run rate are both higher.
Teams — Seattle enters with a .687 OPS, 426 runs, a 3.65 team ERA, and a 1.18 team WHIP. The Mariners are 5-5 in their last 10 games. Their offensive line is lighter, but the pitching staff has been the steadier unit overall. Texas has a .724 OPS, 443 runs, a 4.30 team ERA, and a 1.27 team WHIP. The Rangers are also 5-5 in their last 10. Texas brings the better offensive baseline by OPS and runs, while Seattle holds the cleaner edge on the mound at both the starter and team levels.
