NATIONAL SEEDS
SECURE TEAMS: Virginia, Florida, Vanderbilt, South Carolina, Arizona State, Oregon State
ON THE BUBBLE (IN): Florida State, Texas
ON THE BUBBLE (OUT): North Carolina, Georgia Tech, Southern Mississippi, Texas A&M
No change from last week. The Seminoles strengthened their position somewhat with a series win against Central Florida and a midweek win at Stetson. North Carolina and Georgia Tech are nipping at Florida State's heels for the second national seed spot in the ACC. The Yellow Jackets actually have a better conference mark (18-6) than either team, while UNC (16-8) has the same ACC record as FSU and won the head-to-head series against the Seminoles. All three teams are in the top nine in the RPI, and UNC has the best record against the top 100 (30-10, while the other two teams are both 23-12), so this situation is still very fluid. But the Tar Heels have the most difficult remaining schedule of the three, with a series at Georgia Tech and a home set against Virginia. Of course, that schedule also affords UNC an opportunity to solidify itself as a national seed—it controls its own destiny in this discussion, but it's not an easy road. Florida State's 3-1 record against Florida this season remains its trump card, for now at least. It's also possible that three of those teams could land national seeds, especially if one of the three SEC heavyweights falters or if Texas stumbles.
The Longhorns held their ground with a road series win at Nebraska, leaving them a half-game ahead of Texas A&M in the Big 12 (though they technically trail by percentage points). The season-ending series between the two clubs will go a long way toward determining if either is a national seed; that series is a must-win for the Aggies, who have slipped to No. 18 in the RPI and the outside of the national seed discussion in recent weeks.
Southern Miss is the darkhorse. The Golden Eagles shot up seven spots to No. 10 in the RPI after sweeping UAB last weekend, and they still control Conference USA, with a two-game lead over Rice. The Golden Eagles need to win their last two series—at Houston and against Rice—to overtake one of the teams ahead of them for a national seed. Right now the biggest flaw in USM's resume is just an 0-2 record against the top 25 in the RPI, but a series win against the Owls could help remedy that shortcoming.
REGIONAL HOSTS
SECURE TEAMS: The 12 teams listed in the national seeds discussion above
ON THE BUBBLE (IN): Stetson, Arkansas, Oklahoma, Cal State Fullerton
ON THE BUBBLE (OUT): Texas Christian, Clemson, Rice, Oklahoma State, Miami, Stanford, Fresno State
One change from last week: Arkansas replaces Fresno State as a host. After taking two of three from Florida, Arkansas padded its record against the top 25 in the RPI to 10-8, which compares very favorably to other host candidates in its region like Oklahoma (4-8), TCU (4-5) and Rice (3-2). TCU's series win at Oklahoma State, followed by a midweek win against Baylor, improved the Frogs to 10-4 against the Big 12 this season, giving their hosting chances a major boost. But TCU needs Oklahoma to slip up, because the Sooners still own a 2-0 record against TCU and a stronger RPI (No. 15 vs. No. 26).
Rice, meanwhile, climbed nine spots to No. 14 in the RPI after sweeping a series at Houston. If the Owls win their final two series, including a road set at Southern Miss in two weeks, they might be hard to deny. But competition is thick for host spots in that part of the country.
