Bukauskas (1-1) allowed two runs on three hits over one inning and picked up the loss to the Marlins on Thursday.
Two pitches into his stint, Bukauskas served up a home run to Adam Duvall, which broke a 1-1 tie and sent Miami on to a win. Following a four-outing hitless run after he was called up, Bukauskas has run into trouble, giving up six runs and nine hits over his last three innings.
