On October 4, 2011, in Game 4 of the ALDS against the Tampa Bay Rays, Beltré became the sixth player—the first in a Division Series—to hit three home runs in a Major League playoff game. He added a fourth playoff home run in Game 5 of the 2011 World Series when he went down to one knee chasing an outside curve ball from Chris Carpenter. The St. Louis Cardinals defeated the Rangers in seven games. Beltré finished that postseason with five home runs and nine RBI.
