The Warriors have set a team record with three grand slams in the 2011 season. Matt LeVigne, Tyler Dempsey and Rick Sisco have each hit a grand slam this season. The all-time Major League leader in grand slams is Lou Gehrig--who hit an astounding 23 grand slams in his career. That record has stood for many decades.
I captured this photo of Lou Gehrig's Hall of Fame plaque while visiting Cooperstown a couple of years ago. You can click within the image for a larger view:
