NEW YORK (AP) _ Rain forced postponement of Saturday's game between the Florida Marlins and New York Mets and a matchup of left-handers Dontrelle Willis and Tom Glavine.

The game was rescheduled as part of a July 8 doubleheader. The rainout pushed the two lefties back a day, and they now are scheduled to pitch on Sunday.

Willis has been baseball's most dominant April pitcher since coming to the majors in 2003. He is 8-0 with a 1.76 ERA and three complete games in 11 career starts during the season's first month. He is the only pitcher since 1960 with 10 or more starts in April who is undefeated in the month.

Willis (0-0) was the Marlins' opening day pitcher and pitched five shutout innings, allowing just one hit at Houston. He came out after 104 pitches in a game the Marlins lost 1-0.

Glavine (1-0) also pitched on opening day, working six innings against Washington and gaining credit for a 3-2 victory. It was the 276th win of his career.
