LATE-NIGHT UPDATE: I don't recall as many seeded teams losing their opening games as happened today:
No. 5 Florida coming up short, 2-1, to Florida Gulf Coast.(It also turns out that three Gator starters were dismissed from the team before the game.)
No. 6 Texas losing, 2-0, to Northwestern.
No. 7 Tennessee falling, 1-0, to Miami of Ohio.
No. 12 UCLA getting pounded, 7-2, by Hofstra.
The regionals round, like all others, is double-elimination. Therefore, today's upset victims still have a chance to advance to the next round.
Play is now underway in the NCAA softball Division I regionals. Here is a link to the NCAA softball page, which includes a scoreboard of all games, brackets, and other information. Select games will be shown on the ESPN family of networks. Because there are so many games, I will typically write only about upsets.
