The 29-year-old righty dazzled in his second start of the season, striking out nine A's in 7 1/3 scoreless innings. He’s pitched once against the Nationals in his career, relinquishing two runs in an inning while with the Rockies last season.
Ross rejoins the Nats after a 3-week stint in the Minors focused on improving his mechanics. He made three starts at Triple-A Syracuse, and after yielding 7 runs in 5 innings in the first outing, he gave up 4 runs over 13 frames in next two starts.
