St. Louis, meanwhile, sent Lars Nootbaar to Arizona at the deadline, a move that reads more like a retool than a full sprint at October. That doesn't mean the Cardinals have stopped playing good baseball. It just means the roster in front of Colorado tonight isn't the same one that opened the year.
Feltner's actual season line undersells where he's been lately. Since coming back off the IL in late May, he's turned into arguably Colorado's most dependable arm — a real positive against a Rockies staff that's been gutted by injuries all year. The tradeoff is he's been streaky doing it, with a couple of ugly starts mixed into the stretch, so which version shows up tonight is anyone's guess.
Leahy's numbers are strong, but the Cardinals have quietly been managing his workload — extra rest, capped pitch counts — because he's been vulnerable the third time through a lineup. Colorado's offense has had its moments even during the skid, so if Leahy's still on the mound in the sixth, that's exactly the matchup the Rockies want to see.
