Unfortunately, the most recent data I could find was for the 2008 MLB season. In 2008, 124 grand slams were hit (72 in the AL and 52 in the NL) in 2428 total games for an average of 1 grand slam every 19.58 games. The most grand slams hit in an MLB season is 176 (89 in the AL and 87 in the NL) in 2429 games in the 2000 season for an average of 1 grand slam every 13.80 games.
