"I have thought about it a bunch," Harrison said.
Everybody remembers Game 6. The Rangers had a two-run lead in both the ninth and 10th innings and couldn't put the game away. Instead, the Cardinals rallied for a 10-9 victory and forced Game 7.
It wasn't quite as memorable except for Harrison. The Rangers gave him a 2-0 lead in the top of the first and Harrison retired the first two hitters in the bottom of the inning. Then he walked Albert Pujols and Lance Berkman, setting up a game-tying two-run double by David Freese.
"If I could do it over again, I would have been more aggressive instead of trying to make the perfect pitch," Harrison said. "I was nibbling at the corners and it came back to bite me. I got a two-run lead and I gave it right back. The momentum shifted back to them and we never got it back."
The Cardinals won, 6-2, with Chris Carpenter on the mound. Harrison went four innings and also gave up a go-ahead home run to Allen Craig in the third.
"I would love to experience that opportunity again," Harrison said. "Since then, I have had a lot of time to sit back and think about it and relive those moments. At this point, I wouldn't be as nervous. If I was in that situation again, it wouldn't be so nerve-racking."
