This old guy made a great play to grab Mark Reynolds's second-inning blast in Chicago. He scaled the fence and leaned almost as far over as possible to snag the ball, much to the delight of the folks around him. And, just like his fellow fan from a month ago, in nearly the exact same spot, he knew he had to throw that ball back. Old Man Cubs Fan came prepared.
He didn't have the flare of the spin move to distract people, but he made his move quickly and if you weren't paying close attention, you might not have seen him reach down and grab the dummy ball from the bleachers and throw it back with the real one still in his glove.
Update: Here's a spectacular photo of the catch from the Chicago Tribune:
