Last year, because I felt unlucky, I started looking at how many times I lost or won in the 9th inning (or 5th for F5). It was roughly break even on the results over a season. You'll get luckier the next time.
GL today.
Good luck, although I'm gonna be on the opposite side of you with St. Louis waiting for a better price before I hit submit. The market should take it another 10-15 cents favoring Houston by 1st pitch. If not I'm still content with a +150'sh price regardless.
