(FD) Could be hitting weather & don't have a full handle on new park factors, but neither pitcher has been worse than league average this year (Gray may still be better), while neither offense has been better than league average (BOS 80 wRC+ v RHP may be worse). BOS doesn't have the LHBs to attack Lugo with either. Both quality defenses, Boston one of the best in the league. Boston also top 5 pen estimators L30 days.
