(AP) -- R.A. Dickey became the first pitcher in the majors to win 18 games this season, and Ike Davis hit a three-run homer to lift the New York Mets to a 6-2 victory over the St. Louis Cardinals on Wednesday.

The knuckleballer allowed two runs in 6 2-3 innings en route to his 18th win, the first Mets pitcher to reach the mark since Frank Viola (20-12) and Dwight Gooden (19-7) both did it in 1990.

 Dickey (18-4) gave up eight hits and struck out five to help New York salvage a win to close out the three-game series.

The Mets did most of their damage off of Cardinals starter Adam Wainwright (13-12), who allowed five runs and eight hits in five innings.
