Good. Despite my constant griping--what else is new?--the defense is better this year and that has to be encouraging to the pitchers.
Right now, I'm fine with Devers at 3b, where he's been for several seasons, and Casas at 1b. Casas's reach comes in handy on those throws to first, and I guess we'll just have to live with his lousy work on grounders. If memory serves, his throws to 2b have been good.
So the problem is in the middle infield and here's my thought. Go for the D. If, for example, Mayer is ready on D, bring him up (after he's played some games in the minors this year). Same goes for anyone else who really is good with the glove and the arm.
And live with two lousy hitters because the other 7--Devers, Casas, O'Neill, Duran, Wong/McGuire, Rafaela, and Yoshida--just might be enough. Indeed, Alex Cora has even used McGuire as a DH, which worked pretty well.
