May 9, 1961: Baltimore Orioles first baseman Jim Gentile hits two grand slams in consecutive innings.
Gentile launched the two home runs in the first and second innings of the Orioles' 13-5 win over the Minnesota Twins. It was the first time in major league history a player hit grand slams in two straight innings.
Gentile finished that season with a .302 batting average and 46 home runs, but was overshadowed by one of the most exciting home run races in baseball history.
