In his final postseason performance, Halladay lost to Chris Carpenter and the Cardinals 1-0 in the decisive Game 5 of that 2011 matchup. Earlier in the series, the Cardinals were spurred when a Rally Squirrel scampered on the field.
"I think the one thing I took away from that is you can have the best team on paper, you can have the guys who want it the most," Halladay said. "But when the squirrel runs across home plate while your team is trying to pitch, there is nothing you can do about that. So you really start to realize there are a lot of things out of your control. It takes more than nine guys. It takes nine guys, and it takes the 25 on the roster. It takes the coaches, the staff, and it takes a lot of luck."
