With the win -- top-seeded Mississippi State (38-22) advances to tomorrow's N-C-A-A regional championship at Bill Davis Stadium in Columbus, Ohio. Third-seeded Delaware (45-14) will meet Kent State -- a 9-to-8 winner over host Ohio State in the losers' bracket final -- in this evening's losers' bracket final. Delaware starter Vic Sage (11-3) picked up the win with one-and-a-third innings of relief in the Blue Hens' 5-to-4 first-round win in 10 innings over Ohio State on Friday night. He then came back to go the distance -- throwing 137 pitches -- against Mississippi State. Sage's only mistakes came against Brinson. The 6-foot-5 freshman led off the second inning with a solo shot that tied the score at 1-1.
