I'm not ready to put Espinal at the top of the lineup, but he should be batting ahead of Tapia. When the everyone is healthy it SHOULD be (what it will be will reverse slot 2 and 3):
Springer CF
Vladdy 1B
Bo SS
Teo RF
Gurriel LF
Chapman 3B
Kirk DH
Espinal 2B
Jansen C
6 through 9 are mostly fungible on this team maybe even 5-9 depending on how they're playing on any given day. Obviously you'll sub in Biggio/Tapia when they're playing. Hopefully Zimmer is nothing but a late inning defensive replacement/pinch runner.
And before you ask, no, I don't care that it's all right handed. A good hitter is a good hitter, and our best hitters are all right handed.
