Yeah he's locked up the 7 spot in my opinion, so we've got (in no lineup order per se):
Houston, Tellier, Kurtz, King, Rhino, Winnay, Morales in there moving forward who should be locked in starters in any meaningful game (most of them from here on out).
That leaves two spots left in the lineup, and obviously one of the nine spots goes to whoever is catching, and that's a bit of a lost cause. I like what Walter has been doing there with pinch hitting Nelson the 3rd time through the order, but at some point we may just need to accept Gill may not hit, but he's coming long VERY nicely defensively the last few games and just bite the bullet there.
Javar has struggled a bit lately, so we may need to keep trying to work in Willson/Nelson there. Not sure what happened with Salvino, and we haven't seen Jeter at all lately. Guessing that will continue to just be by committee, but damn it would be nice if somebody could pop a bit, otherwise just ride the hot hand.
