Facing Jarrod Dyson, his sixth batter of the inning, Boxberger appeared to come up favoring his side after his third pitch, which moved the count to 3-0.
Boxberger was immediately lifted and Dana Eveland finished out the inning.
After missing the team's first 49 games due to adductor (core muscle) surgery, Boxberger made his season debut and promptly got ahead of Whit Merrifield 0-2 before retiring him on a foul flyout to right field. He then got ahead of Lorenzo Cain 0-1 before retiring him on a groundout to second.
