Happ is out of the lineup for Wednesday's game against the Nationals.
Happ, who turned 32 on Wednesday, will end up getting the night off for his birthday. Tyrone Taylor will pick up the start in left field in place of Happ, who had been included in the lineup in each of the past six games while going 6-for-24 with two home runs, one double, two walks, three RBI and four runs.
