OAKLAND - A's starter Jesse Hahn left Tuesday night's game in the third inning with a strained right triceps.
The right-hander had surrendered seven hits and four runs when he was visited by manager Bob Melvin and A's head trainer Nick Paparesta after allowing Christian Yelich's leadoff single in the third. Following a short conversation, Hahn headed for the dugout.
The A's already were trailing 4-1 at the time, and Bobby Wahl was called in cold from the bullpen. After being given all the time he needed to warm up, Wahl gave up two doubles, a single and two wild pitches as the Marlins added on three more runs to take a 7-1 lead that they held as of the bottom of the fourth.
Hahn came in 1-3 with a 3.02 ERA over nine games (eight starts) after replacing Raul Alcantara in the rotation in early April. Hahn was sidelined for roughly a month late in 2016 with a strained right shoulder and missed the final three months of the 2015 season with right elbow inflammation.
Since Sean Manaea returned from a shoulder setback May 15, the A's have been operating with what looked like a consistent five-man starting staff with Sonny Gray, Kendall Graveman, Manaea, Andrew Triggs and Hahn.
