(FD) Kay has been better L3 (13.2 K-BB%, 29.8 HardHit%). Facing SEA in their lesser split (76 wRC+ v LHP) w/o Raleigh & Donovan. LHBs (.151 wOBA, .213 xwOBA v Kay & SEA may have to play 3 or 4. Expected to be piggyback between Castillo & Miller, so splitting unit F5 & full game. Castillo 5.78 xERA. CWS LU full of LHBs (.360 wOBA, .347 xwOBA v Castillo since LY, > .350 wOBA even at home against him this year). Actually have CWS with a significant overall offensive edge here (18 points of wRC+). CWS proj. defense 8 FRV edge too. (Would play either down to around +115)
