Well, college baseball nation, it looks as if we were right about the Virginia Cavaliers after all. They made quite an emphatic point by going into one of the toughest environments in our sport and pulling out a series win over Florida State two games to one.

Another big flag was planted in the dirt by Oregon State with its sweep of in-state rival Oregon. The Beavers' starting pitching looks Omaha-ready as they strive to make their sixth trip this June.

Slight hiccups for Louisiana and Cal Poly didn't do huge damage, but let's keep an eye on those two teams that are totally new to this wild success they're having this season. Teams like that tend to wear down in May.

Here are the best of the movers and shakers in this week's Power Rankings.

Of note: Two weeks ago the Pokes had an RPI in the low 80s. After sweeping Kansas on Easter weekend and winning the series at Texas this past weekend, they've made their move up to No. 40. (Hint: They're still better than that.)

9. Florida State (33-11)

12. South Carolina (34-11)

Trending:

Last week: 17

Of note: The Gamecocks gave us a glimpse of how dominant they can be with a pair of 9-3 wins over Alabama on Friday and Sunday. But consistency is still an issue.

18. Florida (30-15)

Trending:

Last week: 13

Of note: Not sure what to make of the Gators. They're still leading the SEC East by three games, but losses to Jacksonville and Florida A&M last week forced them to drop from No. 1 to No. 3 in the RPI.

19. TCU (30-13)

Trending:

Of note: Wow. You know you've played a good schedule when you're five weeks into the Big Ten part of the season and you're still at No. 2 in the RPI. Well done, Hoosiers.
