Detroit Tigers vs Chicago Cubs Starting Lineup — Tuesday, Jul 21, 2026

Detroit has very little history against David Peterson. Gleyber Torres is 1-for-1 with a 5.000 OPS, while Matt Vierling is 1-for-4 with a .250 average and .500 OPS. Kevin McGonigle, Hao-Yu Lee, Dillon Dingler, Riley Greene, Spencer Torkelson, Ben Malgeri, and Jake Rogers have no MLB history vs Peterson.

Chicago has a few more established matchups against Framber Valdez, though the results are mixed. Dansby Swanson has the best line at 2-for-4 in 6 PA with a .500 average and 1.167 OPS, and Nico Hoerner is 1-for-3 with a .333 average and .666 OPS; Carson Kelly is 1-for-5 with a .200 average and .600 OPS. Pete Crow-Armstrong is hitless at 0-for-3 with a .000 OPS, Seiya Suzuki is hitless at 0-for-2 with a .000 OPS, and Alex Bregman is hitless at 0-for-3 with a .000 OPS. Ian Happ is 0-for-5 in 6 PA with a .167 OPS, while Michael Busch and Kevin Alcántara have no MLB history vs Valdez.

Chicago clearly brings more familiarity into this matchup, with several hitters owning multiple plate appearances against Valdez. Detroit’s lineup is far less tested against Peterson, with only Torres and Vierling having faced him in the majors.
