Gotta love Nyjer Morgan. Apparently, he stepped up to plate in the 8th inning with his team winning, hit a double to drive in a run, and then was surprised to see his teammates rushing the field. Turns out that it was actually the ninth inning of a tie game and he just knocked in the winning run.
He continued his wizardry in the post game game interview.

Apparently, he throws up the T because he has an alter ego, Tony Plush.
