Yelich has a 121 OPS+ which is exactly the same as Turang and Frelick is at 111. The difference between the 3 is far too insignificant to think that one is going to make a marked difference in the number of strikes that the #9 hitter sees. All are massive upgrades over Ortiz offensively, who I’m not sure whether we want to be seeing strikes or not.
I also understand why Roberts has Ohtani leadoff, but I would argue that most managers probably would find that to not be optimal.
