He and teammate Ian Kinsler each hit three home runs in the 2010 AL Division Series against the Tampa Bay Rays, marking only the second time in Major League history that two teammates each hit three homers in a postseason series of five games or fewer (joining Babe Ruth and Lou Gehrig, who did it in the 1928 World Series). In Game 5 of the 2010 World Series vs. the San Francisco Giants, Cruz hit a home run off of Tim Lincecum in the 7th inning. It was around this time that Cruz began to refer to his baseball bat as a "boomstick."
