Sixteen regionals. Four days. Seven hosts eliminated, two No. 4 seeds through, and the No. 1 overall seed gone before the bracket had settled into a rhythm. The committee's bracket and the bracket that actually played out are not the same thing.

Los Angeles — Cal Poly

Saint Mary's beat UCLA 3-2 on opening night. Virginia Tech followed the Bruins out the back door. Cal Poly, the No. 3 seed, won three straight — including a 5-2 regional final over the Gaels on Sunday — and became the first team in the field to eliminate both of a regional's top two seeds. The No. 1 overall seed produced zero wins in its own building.

Hattiesburg — Little Rock

Little Rock opened with a 7-4 takedown of No. 9 national seed Southern Miss, then beat Jacksonville State twice — 8-6 in the winners' bracket and 6-3 in the regional final. A Sun Belt No. 4 seed is going to Super Regional weekend. Southern Miss and Virginia, the two highest seeds in the pod, both went home early.

Tallahassee — St. John's

St. John's beat Florida State 6-5 on Friday and never lost. The Seminoles clawed back through three elimination games — Coastal Carolina, Northern Illinois twice, including a 10-inning win — and forced a regional final on Monday. St. John's closed it out 5-4. Another No. 4 seed through the door.

Gainesville — Troy

Florida handled the early part of the weekend, then Troy found its footing. The Trojans beat Miami 9-6 in loser's-bracket play Sunday, knocked off the Gators 16-11 in the regional final opener, and finished the job Monday with a 10-2 rout. A Sun Belt No. 3 seed is heading to the supers. Host Florida is not.

Atlanta — Oklahoma

Georgia Tech opened with a 22-run statement and looked like the No. 2 national seed the bracket expected. Oklahoma came up through the loser's bracket, beat the Jackets 15-8 on Sunday to force a winner-take-all final, and won Monday's regional championship 8-7. The No. 2 seed is out. The Sooners are not.

College Station — USC

Texas State beat USC 5-4 on opening night and made the Trojans look like an afterthought. USC spent the rest of the weekend in the loser's bracket — 19-6 over Lamar, 15-4 over Texas State, 14-3 over Texas A&M on Sunday — and closed the regional Monday with a 7-1 win over the Aggies. Seven games, one regional, and a double-dip at the end.

Lincoln — Ole Miss

This was the regional everyone circled on the schedule. Ole Miss beat Arizona State 7-6 in 14 innings on Friday, handled Nebraska on Saturday, and beat the Sun Devils again 5-4 in 10 on Sunday to advance. The subplot: Landon Hairston was ejected during ASU's elimination win over Nebraska on Sunday afternoon — bat flip, called third strike — and missed the regional final under NCAA suspension rules. Arizona State went home without its best hitter in the game that mattered most.

Auburn — Auburn

Milwaukee's 13-8 opening-night win looked like the upset of the weekend. Auburn dropped into the loser's bracket, beat NC State 17-13 and UCF 9-3, beat the Panthers 8-1 on Sunday to even the regional, and took the winner-take-all final 8-3 on Monday. The No. 4 national seed survived its own building by the thinnest margin.

Morgantown — West Virginia

Kentucky won the 2-3 game and the winners' bracket final, then dropped two straight to West Virginia — 11-9 on Sunday, 6-5 on Monday — to send the No. 16 national seed through. The Mountaineers won four elimination games across the weekend. The last No. 16 seed standing did not go quietly.

Chapel Hill — North Carolina

UNC was never in real danger of going home, but East Carolina made them work. The Pirates beat Tennessee 7-3 in 14 innings on opening night, pushed the Tar Heels to 7-5 on Saturday, and lost the regional final 9-3 on Sunday. Chapel Hill's path was cleaner than the scoreboard suggested.

Tuscaloosa — Alabama

Alabama's regional went to an 11-inning regional final — 9-7 over Oklahoma State on Sunday — after the Cowboys came through the loser's bracket. The Crimson Tide were not dominant, but they were good enough when it counted.

Lawrence — Kansas

Kansas beat Northeastern, took the winners' bracket final over Arkansas 5-3 on Saturday, and closed the regional 13-10 on Sunday. The Jayhawks looked sharp all weekend in their first home regional. This one did not reach a Monday Game 7 — Arkansas ran out of runway in a shootout on Sunday night.

The Ones That Rolled

Four hosts did what the top of the bracket is supposed to do.

Texas (Austin) ran through the pod — 19-1 over Holy Cross, 16-2 over Tarleton State, 6-4 over UC Santa Barbara in the regional final. UCSB pushed back in the last game. Otherwise, the Longhorns barely broke a sweat.

Georgia (Athens) handled a weather-suspended opener against LIU, then beat Liberty twice — 6-2 and 6-1 — to advance without drama.

Mississippi State (Starkville) beat Lipscomb 10-1, dropped Cincinnati 10-5, and finished Louisiana 19-5 on the back end.

Oregon (Eugene) closed out an in-state rival weekend with a 4-1 regional final win over Oregon State after handling Yale and Washington State earlier in the pod.

Sixteen teams. Nine hosts survived. Two No. 4 seeds and a handful of lower seeds among the non-host winners. The supers are set. The bracket has been rewritten.
