OAKLAND, Calif. (AP) Ross Detwiler and John Axford combined on a four-hitter and the Oakland Athletics beat Baltimore 1-0 on Wednesday night to knock the Orioles out of first place in the AL East.
Called up from the minors earlier in the day, Detwiler (1-0) allowed six hits over a career-high eight innings and struck out two while leading the A's to their third consecutive one-run win over the Orioles.
Detwiler was nearly out of baseball after being designated for assignment by Cleveland in July.
