Banwart (10-5) dominated the Arizona batting order over 7 2/3 innings, allowing just a base hit in the fifth and one in the sixth. He retired the side in order in each of the first four innings and at one point struck out six of seven batters.
Krol, who entered with two outs in the eighth inning, struck out all four UA batters he faced to seal WSU's first-ever trip to a super regional and record his 12 save of the year.
Offensively, the Shockers exploded for all three runs in the fifth inning, with Tyler Weber snapping a scoreless tie with a solo home run to lead off the frame and regional MVP Derek Schermerhorn adding a RBI single.
The Arizona softball team lost, 3-0, to Tennessee in the first game of the best-of-three WCWS Championship Series on Monday night.
Taryne Mowatt (40-12) drew the loss after tossing yet another complete game. The junior All-American has pitched every inning in UA's 2007 postseason. She allowed three runs on six hits with six strikeouts. Mowatt's final strikeout of the game was her 500th of the year – marking just the second time an Arizona pitcher has reached that plateau in a single season.
Monica Abbott (50-3) earned the win with a three-hit shutout in which she struck out eight Wildcat hitters.
With two outs in the top of the second, UT's Alexia Clay homered over the outfield wall – just out of the reach of Arizona's center fielder Caitlin Lowe. Clay's fourth home run of 2007 came in Clay's second at-bat of the WCWS.
Arizona's season record moved to 48-14-1 with the loss, while Tennessee improved to 63-6.
