Johnson (1-0) struck out the side in the eighth inning and earned the win in Boston's 7-6 come-from-behind victory over Seattle on Friday.
Johnson gained some ticks on his fastball -- touching 92.9 mph -- while throwing a clean inning and was credited with the win after Mitch Moreland's three-run homer put Boston ahead in the ninth. The left-handed Johnson has thrown an inning in both of Boston's games thus far.
