For our Sunday roundup, let's run through the Top 25 series, then take a look at some other notable results from around the nation:

• (21) Alabama at (1) Vanderbilt: Curt Casali (2-for-4, 4 RBI) and Mike Yastrzemski (3-for-3, 3 R) powered the Commodores to an 11-6 win against the Crimson Tide, completing the sweep. Casali's three-run homer highlighted Vandy's six-run seventh. Vandy improved to 30-3 overall and kept pace with South Carolina for first place in the SEC East—both are 10-2 heading into next weekend's showdown between the teams in Columbia.

• (2) Virginia at (14) Georgia Tech: The Yellow Jackets avoided a sweep with a 10-8 win Sunday. Buck Farmer (7 IP, 10 H, 7 R, 4 ER, 1 BB, 8 K) wasn't his best for Tech but battled and picked up his sixth straight win, as Jake Davies (4-for-4, 2 2B) led Tech's 14-hit attack. Keith Werman capped his big weekend by going 2-for-3 with three RBIs for Virginia.

• (4) Florida at Mississippi State: Preston Tucker's two-run single broke a 1-1 tie in the seventh and provelled Florida to a series-clinching 3-1 win. Karsten Whitson (5.1 IP, 5 H, 1 ER) was solid in a no-decision for the Gators, who mixed and matched on the mound thereafter.

• (5) Arizona State at (19) Oregon State: The Beavers beat ASU 9-6 to complete their first sweep of the Sun Devils since 1966. Oregon State jumped on ASU starter Jake Barrett (2.1 IP, 6 H, 7 ER, 2 BB, 4 K) early on, with shortstop Ryan Dunn (2-for-3, HR, 3 RBI) leading the way. The OSU bullpen shut out the Sun Devils over the final six innings. The Beavers improved to 5-1 in the Pac-10 and put themselves squarely into regional hosting position, as well as the national seed discussion. They also won a road series at Arizona last week.

• (6) Texas A&M at Texas Tech: The Aggies pounded out 21 hits in a 14-8 win Sunday to take a road series in Lubbock. Seven Aggies recorded multiple hits and 10 Aggies got into the hit column, helping Ross Stripling (6 IP, 10 H, 7 R, 4 ER, 0 BB, 9 K) improve to 6-2.

• (16) North Carolina at (7) Florida State: Colin Moran (3-for-4) hit a two-run single to highlight North Carolina's seven-run third inning, propelling the Tar Heels to a 7-6 win in the rubber game in Tallahassee. Chris Munnelly (0 H, 1 ER, 3 BB) failed to get an out in the first inning, but the UNC bullpen came up big, led by Greg Holt (4.2 IP, 8 H, 3 ER) and Michael Morin (3 IP, 2 H, 0 R, 0 BB, 5 K). It was UNC's first series win in Tallahassee since 1995, and it improved the Tar Heels to 12-3 in the ACC. North Carolina is now in the driver's seat for a national seed. Sunday's game also snapped Florida State's streak of 25 consecutive wins on Sundays.

• (8) Texas at/at/vs. Baylor: The Longhorns won their rubber game against Baylor, 5-2, to remain tied with Texas A&M atop the Big 12. Texas broke a 2-2 tie with three runs in the seventh, highlighted by Tant Shepherd's two-run double. Cole Green (6 IP, 2 H, 2 ER, 3 BB, 9 K) was strong in a no-decision, and Corey Knebel worked two perfect innings for his eighth save.

• (9) Fresno State at San Jose State: The Bulldogs salvaged a four-game split at San Jose State with a 5-3 win Sunday. Tom Harlan (5.1 IP, 8 H, 2 ER) was solid in a no-decision for Fresno, which broke a 2-2 tie on Jordan Ribera's three-run homer in the seventh. That's a potentially huge development for the Bulldogs, who need to get Ribera going. Last year's national home run champ has just two so far in 2011.

• (10) Oklahoma at Kansas State: The Wildcats got to OU starter Dillon Overton (4.2 IP, 2 H, 5 R, 0 ER, 4 BB, 5 K) for five unearned runs in the fifth inning, en route to a 6-2 upset and a series victory. Evan Marshall (3.2 IP, 1 H, 0 R) picked up the win in relief for Kansas State, which got 6.2 innings of scoreless, two-hit work from four relievers. The Wildcats have survived their brutal first four weeks of Big 12 play (at Texas, at Baylor, vs. Texas A&M, vs. Oklahoma) with a 4-8 record, and this series breathes life into their NCAA tournament hopes.

• (11) Stanford at Southern California: The Trojans stunned Stanford for the second straight day, winning 6-2 to take the series. Logan Odom (7 IP, 6 H, 5 BB, 8 K) kept the Cardinal offense at bay, and Dean McArdle (2 IP, 4 H, 4 ER) took his first loss of the season for Stanford. Ricky Oropesa had two RBIs to lead the USC offense. After watching Stanford look great in demolishing the Trojans on Friday, I'm frankly shocked that USC bounced back to win this series. Frank Cruz's team improved to 13-19 overall, 4-5 in the Pac-10.

• UC Irvine at (12) Cal State Fullerton: The Titans topped rival Irvine 10-4 to win the series and take control of the Big West. Michael Lorenzen's three-run triple in the fourth put the Titans ahead for good, and Dylan Floro (4.2 IP, 3 H, 0 R) picked up the win with stellar relief work.

• (13) California at (22) Arizona: The Golden Bears and Wildcats split a doubleheader Sunday, but Arizona's win in the first game of the twin bill gave it the series victory. Arizona's Josh Garcia and Robert Refsnyder each homered and combined for seven hits and six RBIs in the Game One slugfest, helping Kyle Simon (7 IP, 14 H, 7 R, 6 ER) pick up the win despite surrendering 14 hits. Tony Renda had four hits in each game for Cal, and he also drove in three runs in the nightcap, as the Bears broke open a 9-7 game with six runs in the eighth.

• New Mexico at (15) Texas Christian: All nine TCU starters recorded hits in support of Steven Maxwell (9 IP, 9 H, 2 ER, 0 BB, 8 K), as the Horned Frogs beat New Mexico 6-2 in Sunday's rubber game. It was Maxwell's first career complete game.

• (17) Louisiana State at Arkansas: The Hogs beat LSU in walk-off fashion for the second straight day, 5-4, to sweep the Tigers for the first time since 2004. Austin Nola's grand slam put LSU ahead 4-3 in the sixth, but Arkansas answered with a run in the bottom of the frame, then broke the tie on Kyle Robinson's game-winning sacrifice fly in the ninth. Both teams have lost three of their first four SEC series, but LSU has been swept twice to fall into the basement, while Arkansas has climbed to 6-6.

• (18) Southern Mississippi at Memphis: The Golden Eagles avoided a sweep with an 8-5 win Sunday. Memphis took advantage of four USM errors to score five unearned runs against Jonathan Thompson over the first two innings, but Adam Doleac's grand slam in the seventh tied it up, and B.A. Vollmuth's two-run shot in the eighth put Southern Miss ahead for good.

• Florida International at (20) Troy: Rudy Flores (3-for-5, 2 R, 4 RBI, 2 2B, HR) led FIU's 15-hit attack, as the Panthers beat Troy 12-4 to avoid a sweep. The Trojans still lead the Sun Belt Conference by two games over Western Kentucky, which also dropped its series finale against Louisiana-Lafayette.

• Missouri at (23) Oklahoma State: Dane Phillips (2-for-4, 2 R, 4 RBI, HR) hit a two-run single to highlight OSU's five-run fourth inning, leading the Cowboys to a 7-3 win and a series sweep of Missouri. Andrew Heaney (2.2 IP, 3 H, 1 R, 0 ER) lost his starting spot but picked up the win in relief of Randy McCurry (2.1 IP, 4 H, 2 ER). The Cowboys have won three straight series since opening Big 12 play with a series loss at Kansas.

• (24) UCLA at Washington State: With Adam Plutko (8 IP, 2 H, 1 ER, 1 BB, 7 K) dealing, the Bruins took a 2-0 lead into the ninth and appeared on the verge of a big sweep, but Washington State rallied with three in the ninth to salvage a win. Taylor Ard's two-run single tied the game, and Jason Monda won it with a walk-off RBI single against Mitchell Beacom. The Cougars desperately needed the win; they improved to 2-7 in Pac-10 play, while UCLA fell to 7-2.

• Kennesaw State at (25) Stetson: Kurt Schluter (6 IP, 4 H, 1 ER, 4 BB, 5 K) improved to 6-0 in Stetson's 4-3 win against Kennesaw State, completing a sweep. The first-place Hatters improved to 12-3 in the A-Sun.
