List of National League annual slugging percentage leaders
List of National League Slugging Percentage Leaders The National League slugging percentage Leader is the Major League Baseball player in the National League who has the highest slugging percentage in a particular season. In baseball statistics, slugging percentage' (abbreviated SLG) is a measure of the power of a hitter. It is calculated as total bases divided by at bats: formula_1 where "AB" is the number of at-bats for a given player, and "1B", "2B", "3B", and "HR" are the number of singles, doubles, triples, and home runs, respectively. Walks are specifically  excluded from this calculation. Currently, a player needs to accrue an average of at least 3.1 plate appearances for each game his team plays in order to qualify for the title. An exception to this qualification rule is that if a player falls short of 3.1 plate appearances per game, but would still have the highest batting average if enough hitless at-bats were added to reach the 3.1 average mark, the player still wins the slugging percentage championship. The latest example of this exception being employed was in 2007, when Ryan Braun had a .634 slugging percentage, but only  492 plate appearances – 10 short of the 502 necessary. The addition of 10 hitless at-bats would have lowered his slugging percentage to a value that was still better than anyone else in the league, so Braun was the National League slugging percentage champion. A similar situation occurred when Tony Gwynn won the NL batting title in 1996.
