WasWatching reviews the botched popup that made the Orioles blowout a slightly larger blowout.

In the YES replays, you clearly see Jeter moving his mouth when the pop is in the air. It appears that he's saying "I got it!" a few times. In the same replays, you never see A-Rod open his mouth, at all.

Rodriguez was clearly planted under the ball. He was in perfect position to catch it. Jeter had to range to his right to get towards the ball. I would offer that Derek had to move around 10 feet, away from his position on the pitch, towards the foul line, to get to where the ball was going to land.

Jeter went behind A-Rod and their gloves bumped as they both reached up for the ball. That appeared to be the only serious contact between the two players. It seemed as if their gloves met just as the ball was going into the pocket of A-Rod's mitt - and that knocked the ball loose.

The rule on the Yankees should be that Jeter catches all pop ups, even the ones hit directly at another fielder, to make up for all the ground balls that go through the shortstop position. :-)
