Oakland starter Addie Joss improved to 3-0, despite allowing 7 runs on 11 hits in 6 innings against the Detroit Rockets. Most of it was thanks to an Oakland offense that hit 5 home runs against Detroit starter Frank Tanana. Joe Gordon hit his 1st homer of the season, a 2-run shot in the 2nd inning. Josh Gibson and Reggie Jackson added 2-run homers of their own in the 3rd. Tanana exited in the 4th after allowing back-to-back homers to Lou Boudreau and Hank Greenberg. Joss allowed home runs to Miguel Cabrera and Mark McGwire, part of 6 runs allowed in the 1st two innings. But he settled to allow just one more run the rest of his start. Oakland added three unearned runs in the 7th thanks to a Lou Whitaker throwing error. The loss dropped Detroit below .500 at 12-13. Oakland improved to 10-15.
