Cal Raleigh hit a game-winning grand slam in the bottom of the ninth inning and the Seattle Mariners stormed back from a four-run deficit in the eighth to beat the Chicago White Sox 8-4. Raleigh’s walk-off drive came against Jordan Leasure after the AL West-leading Mariners scored four times in the eighth to tie it. Dominic Canzone led off with a homer against starter Erick Fedde before Michael Kopech gave up three runs and four hits. Mitch Haniger knocked in two with a bases-loaded single, and Luke Raley drove in the tying run with a bunt single. Luis Robert Jr. and Corey Julks homered for the major league-worst White Sox.
