The Mets’ power bats were finally cooled off Sunday, but opposing pitching had nothing to do with it. After they played through frigid temperatures and snow on Friday and bitter cold on Saturday, the Mets’ series finale against the Twins was postponed Sunday due to a “wintry mix” of snow and rain in the Twin Cities. The awful weather prevented the Mets from going for their first series sweep of the year, but the end result could be a dream matchup next Friday in Queens. Matt Harvey, who flirted with a no-hitter Saturday in Minnesota, will be given an extra day of rest and is scheduled to start Friday at Citi Field against Stephen Strasburg and the Nationals. It will be a matchup of two of the premier young righties in the game as Harvey is 3-0 with an 0.82 ERA and Strasburg is 1-2, 2.95 after taking a loss Saturday. But first things first: the Mets — who have 15 homers in 11 games and are the only team in baseball to homer in every game this season — will play four games at Coors Field, weather permitting. While the long parade should continue in thin air, three of the games will be started by pitchers not named Jon Niese or Harvey. Dillon Gee, who would’ve started Sunday, will pitch Monday, followed by Aaron Laffey. That will push back Jeremy Hefner to Wednesday and Niese to the series finale. The back of the rotation has struggled so far this season, with Gee and Hefner coming off three-inning starts in Philadelphia where they were pounded. Laffey, a spot starter who was called up to fill in for injured starter Shaun Marcum, could not get out of the fifth in his start against the Marlins on April 7.
