Opossum scurries onto A's field, helps team with walk off win

The Oakland Athletics offense needed a spark Monday night, and it may have come from an unlikely source. It wasn't a player, but an opossum!

The animal scurried along the wall in left field at O.co Coliseum and appeared to give the team the rally they needed to pull off a win in the bottom of the 10th inning. The A's went on to defeat the Tampa Bay Rays 3-2.

The opossum quickly vanished from the field, but he now also has his own Twitter account @rallypossum.
