Eovaldi (undisclosed) left Wednesday's contest against Boston after the first inning, Jared Diamond of the Wall Street Journal reports.
Eovaldi threw just 12 pitches before getting replaced by Chasen Shreve after the end of the first. Shreve was up in the bullpen during the inning, so something was clearly wrong with Eovaldi right away Wednesday night. The team hasn't released any information on the expected injury as of yet, but news on his departure will likely come out before the game is over.
