LH SP available

[Cardinals]

I have four pretty good lefty SP: Jose Quintana, Pat Corbin, Andrew Heaney, Marco Gonzales.

I'd like to trade one for a righty. Can also add a bat or two to the deal as well if it's an upgrade.

Moved a few pieces. Still looking to make a few moves. Have these guys available:

Gregory Polanco
David Peralta
Jose Martinez
Patrick Corbin
Mike Foltynewicz
Aaron Sanchez
Andrew Heaney
Justin Verlander
Ian Kinsler
Seuly Matias

Trying to either consolidate the bats or upgrade in the rotation. Prospects also welcome depending on who we are talking about.
