I know MBB and WBB have had successes in post season previously but in SB you have to play on a host's home field against their home fans to survive and advance. The double elimination nature almost makes forcing the regional finals into an additional elimination game almost like advancing in basketball to a sweet 16. They were really playing at a high level I thought the whole weekend, even the first loss to bama, they had taken a lead twice only to have a bad inning where a series of pitchers struggled to get them out. I don't think there's ever been a post season set up where it more against the odds to have success over a series of games than what our softball women faced.
The regular season was a middle of the pack performance, but the post season run was exceptional, considering the odds and environment.
