TUCSON, Ariz. -- Johnny Field hit a third-inning grand slam and drove in seven runs as Arizona blitzed Louisville 16-3, and the Wildcats won their NCAA baseball regional Sunday. Arizona, which was the top seed in the regional it played at home, will play a best-of-three Super Regional against St. John's. The Red Storm (39-21) was seeded third in the Chapel Hill region, but it advanced with a win over East Carolina and two victories over host North Carolina. The Cardinals (41-22) had advanced to the Sunday night game by eliminating Missouri 11-3 earlier in the day. The first team eliminated in the Tucson regional was New Mexico State, which lost to Louisville on Friday and to Missouri on Saturday. The Wildcats (40-17) cruised through their first two games, pounding Missouri 15-3 and Louisville 16-4. Field finished 4-for-6 Sunday, and teammate Riley Moore went 4-for-4. James Farris threw a complete game for the Wildcats, allowing three runs (two earned) on 12 hits. He struck out seven and walked one.
