ATLANTA (AP) _ The Atlanta Braves set a major league record with their 12th grand slam of the season Wednesday night against the New York Mets.

Ryan Klesko hit the bases-loaded homer in the first inning off Bobby Jones. The Braves eclipsed the grand slam record set a year ago by both Seattle and Baltimore.

Klesko's homer highlighted a nine-run first, and the Braves missed another slam by only one batter. After loading the bases again with one out, Kenny Lofton hit a sacrifice fly and Jeff Blauser followed with a three-run homer.

Jones didn't retire a batter in the first, leaving the game after being charged with eight runs (four earned) on three hits and four walks.

Chipper Jones has hit three grand slams this season for the Braves, while Klesko and Blauser have two apiece. The others were hit by Javy Lopez, Keith Lockhart, Tim Spehr, Andruw Jones and Eddie Perez.
