Report: Athletics recall pitcher Jesse Hahn

The Oakland Athletics have reportedly called up pitcher Jesse Hahn, who missed the last three months of 2015 with an arm injury, to start Saturday's game against the Houston Astros, according to Susan Slusser of the San Francisco Chronicle.

Hahn would start in place of Kendall Graveman, though no reason for the possible rotation shuffle was given.

The 26-year-old posted a 3.35 ERA while striking out six batters per nine innings last year in his first season with Oakland. He didn't pitch after July 1, however, thanks to a forearm strain. Following a rough spring training he was sent to Triple-A Nashville, where he's rebounded with a 2.04 ERA in four starts with the Sounds.

This would be the second time in a matter of days that Oakland has reached down to the farm for pitching help. On Wednesday, the team called up top prospect Sean Manaea, who'll make his big-league debut Friday.
