Mike Fiers remained unbeaten in an Oakland uniform, working six solid innings to lead the Athletics past the Baltimore Orioles 3-2 on a damp Tuesday night.
Oakland extended its winning streak to five games and is 33-15 since the All-Star break, the best mark in the majors during that span. The Athletics hold the second AL wild-card spot behind the Yankees.
Fiers (12-6), who was acquired from the Tigers on Aug. 6, allowed one run and four hits with seven strikeouts and a walk. He is 5-0 in seven starts with the A's and has won a career-best six straight decisions overall.
Stephen Piscotty went 3 for 4, including an RBI single in a three-run third inning. He extended his hitting streak to 12 games and has driven in a run in six straight.
Adam Jones was back in the starting lineup for the first time since Wednesday and had a pair of hits for Baltimore, which has lost five straight and has the majors' worst record (41-103). Jonathan Villar drove in both Orioles runs with a homer off Fiers in the sixth and a single in the eighth off Lou Trivino.
Jeurys Familia worked a perfect ninth for his 18th save since being acquired by the Mets on July 21.
Orioles right-hander Alex Cobb, who was scratched from his scheduled start Sunday with a blister on his throwing hand, pitched two scoreless innings before departing with the same apparent injury.
Mike Wright (3-2) entered in the third and was hit in the left foot by a sharp grounder from Ramon Laureano, the second batter he faced. Matt Chapman followed with an RBI double, and Khris Davis and Piscotty drove in runs with singles.
Wright settled down to retire the next seven batters.
