Dillon Gee will start tonight, followed by Aaron Laffey tomorrow, Jeremy Hefner on Wednesday, and Jon Niese on Thursday.
Matt Harvey is scheduled to start Friday's game against Stephen Strasburg and the Nationals at Citi Field.
Laffey starting tomorrow could depend on whether or not tonight's game (or other games in this series) gets played. Currently, the forecast is calling for 3-5 inches of snow in Denver tonight, and so it's very possible tonight's game gets moved to another date. If the Mets have to play one doubleheader this week, the Mets could conceivably move Laffey into the bullpen and skip his turn in the rotation. However, the snow and cold could play a role in the rest of the series as well, which could further impact the rotation for the remainder of the week.
