Through the span of seven months, 20 major league sluggers have combined to produce 25 of the longest home runs recorded during the 2013 season.
Atlanta's Evan Gattis clobbered the longest home run of the regular season with a 486-foot bomb off Phillies ace Cole Hamels early in the second week of September. According to ESPN Home Run Tracker, Gattis' long ball beat the second-farthest home run of the year by 10 feet.
Of the 20 batters, only three were actually participants in the 2013 Home Run Derby -- New York Mets third baseman David Wright, Detroit Tigers star Prince Fielder, and Baltimore Orioles first baseman Chris Davis.
San Francisco's Hunter Pence (2), Los Angeles Angels star Mark Trumbo (2), Blue Jays center fielder Colby Rasmus (2), and Boston's Mike Napoli (3) were each listed multiple times this year in the top 25 longest homers.
