Mike Hessman breaks the minor league baseball home run record with the 433rd round-tripper of his nearly 19-year career, a grand slam against the Lehigh Valley Ironpigs in the Mudhens’ 10-8 extra-inning International League (AAA) loss at Toledo’s Fifth Third Field. The 37 year-old first baseman, who played parts of five seasons with the Braves, Tigers, and Mets, surpasses Buzz Arlett, who established the mark in 1936 while playing for the Minneapolis Millers.

Adrian Beltre hits for the cycle for the third time in his career when he gets all four hits by the end of the 5th inning in the Rangers’ 12 – 9 win over the Astros. The last player to hit three cycles was Babe Herman, who hit his third in 1933; Bob Meusel and John Reilly are the only other members of this exclusive club.

Clayton Kershaw strikes out Mike Trout looking with a wicked curveball, marking the first time that reigning MVPs have faced one another in a major league game. The interleague contest between the two LA teams ends with Dodger southpaw keeping the Angel outfielder 0-for-3 while hurling eight innings in the team’s 3-1 victory over the Halos at Chavez Ravine.

2015 – A nine-year-old bat boy is killed when he is struck in the head by a follow-through swing while standing near the on-deck circle at the National Baseball Congress World Series in Wichita, KS.
