WEST SACRAMENTO, Calif. (AP) — Randy Arozarena hit one of Seattle’s five home runs in a 19-1 shellacking of the Athletics on Saturday night, the Mariners’ biggest ever margin of victory.

Seattle Mariners 19, Athletics 1: Box Score

J.P Crawford, Dominic Canzone and Cole Young each added two-run homers, and Michael Arroyo had a solo shot for his first big league home run. Weston Wilson had five hits and scored three runs.
