Toronto Blue Jays vs Seattle Mariners Starting Lineup — Saturday, Jul 4, 2026

Vladimir Guerrero Jr. has the strongest track record against Logan Gilbert, going 6-for-15 in 17 PA with a .400 average and 1.404 OPS. Andrés Giménez has also had some success, going 3-for-9 in 10 PA with a .333 average and .844 OPS, while Daulton Varsho is 1-for-6 with a .167 average and .334 OPS and Ernie Clement is 1-for-5 with a .200 average and .400 OPS. Nathan Lukes, Kazuma Okamoto, Yohendrick Piñango, Sean Keys, and Brandon Valenzuela have no MLB history vs Gilbert, so much of Toronto’s order is seeing him for the first time.

J.P. Crawford stands out most for Seattle against Shane Bieber, going 6-for-12 in 14 PA with a .500 average and 1.000 OPS. Victor Robles is 1-for-2 in 3 PA with a .500 average and 1.167 OPS, while Cal Raleigh is 2-for-8 with a .250 average and .500 OPS. Randy Arozarena is hitless, going 0-for-5 in 6 PA with a .167 OPS, and Dominic Canzone is hitless in 2 AB, going 0-for-2 with a .000 OPS. Josh Naylor, Luke Raley, Cole Young, and Colt Emerson have no MLB history vs Bieber.

Seattle appears to have slightly more lineup familiarity with the opposing starter, led by Crawford’s extensive success. Toronto has the best single matchup in Guerrero, but more of its hitters are facing Gilbert for the first time.
