Barnes (1-0) pitched a scoreless inning in Friday's 8-7 victory over the Blue Jays.
The 25-year-old right-hander now has two consecutive scoreless appearances, and needed only nine pitches to get out of a perfect sixth inning. After posting a 1.65 wHIP over 43 innings in 2015, Barnes has encouragingly only issued one free pass over his first two trips to the mound this season.
