Tuesday was chock full of notable upsets and big rivalry games. Here's a rundown:

• Darnell Sweeney's two-run double in the ninth inning propelled Central Florida to a 4-3 upset at No. 4 Florida. It was redemption for Sweeney, who had committed an error at shortstop in the eighth to allow Florida to break a 2-2 tie. Center fielder Ronnie Richardson recorded two strikeouts in a perfect ninth against the heart of Florida's order to pick up the save in his second career mound appearance. In theory, Florida's absurd pitching depth should give it an advantage against everyone in midweek games, but four of the Gators' six losses this season have come in midweek play. UCF, meanwhile, bounced back after being swept at home by Southern Miss to win a midweek road game against a ranked for for the second straight week.

• Arizona State improved to 3-1 this season against rival Arizona with a 10-5 win in Tucson. Deven Marrero had four hits to lead ASU's 12-hit attack. Arizona, which committed four errors in the infield, has lost five of its last eight games.

• In a midweek, nonconference edition of the Bedlam rivalry, No. 10 Oklahoma beat No. 23 Oklahoma State, 8-3. Freshman lefty Dillon Overton (6.1 IP, 4 H, 0 R, 2 BB, 8 K) picked up the win with sterling relief of Jack Mayfield, and Garrett Buechele had four RBIs to lead the Oklahoma offense.

• In another major rivalry game, Louisiana State topped Tulane 7-5 in New Orleans. The Green Wave led 5-4 after six innings, but LSU tied it on a squeeze play in the seventh and went ahead for good with two in the eighth, with JaCoby Jones' RBI single breaking the tie. Tulane has dropped six straight, and it also lost righthander Nick Pepitone with a sore muscle in his right shoulder blade. Pepitone had been slated to move into the weekend rotation this weekend. "I don't know how to react to that; it's the most unprecedented thing I've ever seen in my entire life," Tulane coach Rick Jones told the (New Orleans) Times-Picayune, referring to his team's spate of pitching injuries. "Of our top six pitchers, five are down (two out for the season after elbow surgery). I don't even know what to do." Jones remains stuck on 999 career wins.

• Houston upset No. 6 Texas A&M, 3-2. Codey Morehouse (7.2 IP, 5 H, 2 ER, 2 BB, 6 K) was strong in a no-decision for the Cougars, who broke a 2-2 tie with a run in the ninth on Chase Jensen's RBI single. Houston isn't overly talented, but the Cougars have played hard for first-year coach Todd Whitting, and they have won four straight games (including a sweep at Tulane this past weekend) to improve to 16-14. Houston has played itself into the NCAA tournament bubble discussion.

• Leadoff man Tyger Pederson went 5-for-5 with two RBIs to lead Pacific to a 7-4 upset of No. 13 California. Righty Kevin Miller (4 IP, 6 H, 4 R, 2 ER), who has been a dynamo this year for Cal, took the loss.

• Kennesaw State scored three runs in the ninth against Luke Bard to beat Georgia Tech, 7-6. Ray Anderson delivered a walk-off RBI single for the Owls. Georgia Tech pitchers issued a combined 11 walks, six of them from starter Matt Grimes.

• Jordan Nicholson (6 IP, 7 H, 0 R, 4 BB, 4 K) and two relievers shut out Rice in Louisiana-Lafayette's 2-0 win in Houston. The Owls had 10 hits and drew six walks but left 18 men on base.

• Mississippi State earned a big win at Southern Mississippi, 5-4. Luis Pollorena (5.2 IP, 1 H, 0 R, 0 BB, 6 K) earned the win with stellar relief work, and the Bulldogs surged ahead with two runs in the seventh. Center fielder C.T. Bradford led the MSU offense with three hits and two RBIs. Like UCF, Mississippi State rebounded nicely after getting swept this past weekend (by Georgia).

• No. 21 Alabama mustered just three hits in a 4-2 loss to Samford. Phllip Ervin homered and drove in all four of Samford's runs. That's a huge win for the Bulldogs, who have legitimate at-large aspirations with a 20-11 record and an 8-4 start in Southern Conference play, but need to boost their low-70s RPI.

• No. 20 Troy salvaged a season split with Auburn, bludgeoning the Tigers 14-6. Logan Pierce (4-for-5, 2 2B, HR, 7 RBI), the son of Troy coach Bobby Pierce, went bonkers for the Trojans, leading a 15-hit barrage. Auburn also had 15 hits but left 13 men on base and committed three errors. The Tigers are in a serious rut, having lost eight of their last nine games since winning a series against Arkansas to improve to 14-6. Now they're just a game over .500, with back-to-back road series on the horizon (at Kentucky and LSU).

• Lefthander Sam Stafford threw seven no-hit innings, striking out 11 while walking four, in Texas' 8-1 win against Texas A&M-Corpus Christi. The Islanders did not record their first hit until the ninth inning against Josh Urban.

• Coming into the year, Texas Christian expected Erik Miller to fill its closer role, but the righthander seems to have found his niche as the midweek starter. In his second career start, Miller went seven shutout innings in a 2-0 win against Texas-Pan American. Miller allowed seven hits and no walks while striking out four to improve to 1-5 on the season. Brance Rivera's 27-game hitting streak came to an end for TCU.

• North Carolina's potent offense kept on chugging, rapping out 14 hits in a 12-6 win against Winthrop. Leadoff man Ben Bunting led the way with three hits and two RBIs for the Tar Heels.

• Virginia righty WIll Roberts followed up last week's perfect game with seven innings of three-hit, shutout ball in a 2-0 win against Radford. Roberts did not issue a walk and struck out six to improve to 6-0, 0.96 with 47 strikeouts and three walks in 47 innings.

• Jackie Bradley Jr. sat out with a back injury sustained while lifting weights Monday (he's day-to-day and expected to play this weekend), but South Carolina still erupted for 20 hits in an 18-2 win against South Carolina-Upstate. Christian Walker had a monster day, going 5-for-6 with a homer, a double, four runs and five RBIs.

• Every time you think UCLA is finding its groove, the Bruins take a step back. UC Riverside came from behind with a run in the ninth to force extra innings Tuesday, then beat the Bruins 5-4 in 11. The Highlanders got to Nick Vander Tuig in the 11th for back-to-back doubles by Kyle Boudreau and Bryan Horst.

• Clemson bounced back from a sweep at the hands of North Carolina with a much-needed 5-4 win against Coastal Carolina. The Tigers came from behind with a run in the ninth on Dominic Attanasio's game-tying, pinch-hit RBI double, then won it on Jon McGibbon's walk-off, pinch-hit RBI single in the 10th.

• North Carolina State has righted the ship since starting the season 10-10. The Wolfpack earned a big 4-2 win against East Carolina on Tuesday to improve to 18-12. Pratt Maynard had three hits for the Wolfpack, including a two-run single in N.C. State's decisive three-run seventh.

• Cody Asche and Bryan Peters combined for four hits and five RBIs to lead Nebraska to an 8-5 win against rival Creighton in Lincoln.

• Western Kentucky earned a big win against in-state power Louisville, 15-5. Catcher Matt Rice (2-for-4, 2 R, 3 RBI) led a balanced 16-hit attack for WKU, which improved to 18-11. Both these teams could wind up on the NCAA tournament bubble, so this game could have ramifications down the road. Louisville won the first meeting between the two teams last week.

• Memphis beat Mississippi, 9-2. Memphis shortstop Chad Zurcher, the national batting leader, managed to raise his average from .505 to .521 with a 3-for-3 day, and DH Eli Hynes added two hits and three RBIs. Zurcher's on-base percentage climbed to .624, also the best mark in the nation. Sam Moll (7 IP, 2 H, 0 R, 2 BB, 8 K) was outstanding for the Tigers.

• Washington State, desperate for a win after losing eight of its last 10 games to fall below .500, cooled off Gonzaga, 11-6, in Spokane. All four members of Washington State's starting infield homered in the game.

• Baylor continued to slide, dropping a 3-2 decision at Sam Houston State in 10 innings. The Bearkats came from behind with two in the eighth to tie it, then won it on Braeden Riley's walk-off RBI single in the 10th against Brooks Pinckard. Baylor has lost six of its last eight.
