Hammel will start Game 4 of the NLCS against the Mets on Wednesday, Jess Rogers of ESPN Chicago reports.

EDGE Analysis

Hammel had already been considered the likely option rather than Jon Lester on short rest, but the Cubs have now made the decision official. He'll either be looking to keep the Cubs' season alive or try to knot up the series at 2-2 depending on the result of Tuesday's Game 3.
