This play took place in the same game that the bad calls were made on Swisher.
In the fifth inning, Jorge Posada was on third base and Robinson Cano was on second. Nick Swisher came up to the plate (I guess he does have to do with this one, too).
He hit a ground ball, and Posada was caught in a rundown in-between third base and home plate. Cano ran down to third, assuming that Posada would get out.
Unfortunately, Posada got back to third safely. He knew that he would be out, so he stepped off the base to let Cano be the safe runner. Cano seemed to have the same thought, so he stepped off, too. This left two runners off bases and none on.
The catcher had ran Posada back to third, so he quickly tagged both Posada and Cano. Immediately after Cano was tagged, he stepped back onto the base (great timing, right?). The umpire saw Cano's foot on the bag and called him safe, breaking up the double play.
