Back to the lineup/ batting order for a sec.
Here’s the Jays main 11 players career splits vs lhp/ rhp in wRC+
Varsho: 66/112
Bo: 147/121
Springer: 145/130
Kirk: 126/124
Vlad: 115/140
Chapman: 120/119
Jansen: 83/105
Espinal: 125/91
Biggio: 101/106
Merrifield: 115/98
KK: 84/102
Didn’t think I’d see Espinal hitting lefties better than Vlad, but there it is.
Strictly by This measure vs lefties you’d see a lineup like
Bo SS
Springer RF
Kirk C
Espinal (I know he won’t hit cleanup…relax) 2B
Chapman 3b
Vlad 1b
Merrifield LF
Biggio DH
Kiermaier CF
This lineup would be very good defensively and only have 1 hitter below average career vs Lefties in Kiermaier. I doubt they’d go this route and they’d probably have Jansen in the DH spot due to recent successes. Last seasons his LHP wRC+ was 136.
It looks like they’ll keep Vlad top 3 no matter what so what I suspect the LHP lineup will look like is:
Springer
Bo
Vlad
Kirk
Chapman
Jansen
Merrifield
Espinal
KK
Could they swap a place here or there, sure. Espinal ahead of Merrifield, Jansen 5th over Chapman…sure.
Vs RHP is probably not a big change from the above. Biggio probably swaps out Espinal, Varsho in for Merrifield. Top 6 hitters stay the same, bottom 3 would be Varsho, Biggio, KK, unless they wanted to split the lefties up or just continue using Merrifield at 2b instead of Biggio. I think they’ll probably run with Biggio initially though to see if the shift restrictions ends up being a boon for him. If they do they probably drop Jansen one place and move Varsho to 6th.
