In all of Red Sox history spanning over 100 years, this was the first "round the horn triple play" ever turned by the club. In the 20th century, only 60 of this variety - third to second to first - have been completed. It is considered one of the most difficult feats in major league sports.
In a previous post, I wrote that the "straight steal of home," which was accomplished by Jacoby Ellsbury in 2009 against the Yankees, was one of the rarest feats in baseball, but it turns out that the round the horn triple play is even more rare.
