If the roster had to be put together tomorrow I would go with something like this:
Bench of: Cervelli, Flowers, Hamilton, Joyce, Camargo
This assumes the return of Muk and Ender.
Starting pitchers: Soroka, Keuchel, Teheran, Fried
Bullpen: Melancon, Greene, Jackson, Martin, Folty, Tomlin, Newk, Blevins
Some key decisions:
1) Do we carry Hamilton? I think the answer is yes given his value as a pinch runner and defensive replacement in a high leverage situation.
2) Do we carry 3 catchers? I think the answer is yes given the increased flexibility this gives Snit to pinch run for them and also use them as pinch hitters.
3) Who do we carry of Hech, Culberson and Camargo? I think we carry just one. You need a backup infielder. But you don't need more than one given the strength of our regular infield crew. You carry the one who can help you most as a pinch hitter.
4) Do we carry Duvall and/or Riley. I think the choice is between one of those two versus the catchers. Going with two catchers reduces your flexibility. But if one of Duvall or Riley is swinging a hot bat, I could see a case for carrying one of them over carrying three catchers.
5) As far as the relievers go, I think Swarzak, Sobotka, O'Day, Minter and Dayton (and maybe others) still have a chance to make their cases. The guys on the bubble in the pen are Tomlin and Blevins. Ideally, we would carry 3 lefties against an opponent with good lefty hitters (such as the Dodgers or Cubs). But if there are only 2 lefty relievers we have confidence in, so be it.
