If Yelich couldn’t go in the playoffs lineup would probably be Canha, Frelick, Taylor in the OF with Santana, Turang, Adames, Monasterio around the IF, Contreras catching and Donaldson at DH.
If one of those three OF went down in addition to Yelich, it appears Perkins is the next man up as of now.
Would pretty much need three OF to go down at this point before Wiemer’s name comes up in the starting lineup.
And even then, Mitchell could pass him in the interim.
