OAKLAND, Calif. — Marcus Semien hit a two-out, three-run home run in the sixth inning to help Chris Bassitt earn his first win this season, and the Oakland Athletics beat the Baltimore Orioles 5-0 on Tuesday.
Brett Lawrie added an RBI triple and Eric Sogard scored twice as Oakland won for only the third time in 12 games.
Bassitt (1-4) gave up five hits and had a season-high seven strikeouts over seven innings. The 25-year-old rookie's only other big league win came Sept. 22, 2014 against Toronto while Bassitt was with the Chicago White Sox.
Francisco Rodriguez pitched the eighth and Fernando Abad worked the ninth to complete Oakland's AL-leading 14th shutout.
