Rooker went 1-for-4 with a two-run home run and a walk in an extra-inning loss to the Mariners on Saturday.
Rooker took Emerson Hancock deep in the fifth inning with Max Schuemann aboard to cut a 3-0 deficit to one run. The round tripper marked Rooker's first time leaving the yard since Sept. 16 and puts him just one shy of reaching the 40-homer mark heading into the final day of the regular season Sunday.
