Fujinami will serve as the Athletics' opener Friday against the Marlins, Matt Kawahara of the San Francisco Chronicle reports.
Fujinami's first season in the majors has certainly been rough, as he holds a 12.00 ERA and 1.97 WHIP through 30 innings. However, he's seen an uptick in performance recently, allowing one run on one hit over 2.1 frames. Fujinami will likely stay in Friday's game for an inning or two before turning things over to Hogan Harris, who will take on most of the workload.
