TEMPE, Ariz. - The CSUB softball team lost a pair of games Thursday as it opened its first season of active NCAA Division I membership on day one of the Arizona State Kajikawa Classic.

The Roadrunners dropped a heart-breaker in their first game as North Texas scored seven unanswered runs, including four in the top of the 11^th, to take an 8-4 decision. In the nightcap, No. 9 Oklahoma proved every bit the national title contender with an 11-2 win.

CSUB got RBI singles in the opener from Ryane Petersen (Fresno/Fresno State), freshman Jazmine Lee (Garden Grove/Los Alamitos HS) and Kasie Muro (Tehachapi/Santa Barbara CC) to jump to a 4-1 lead, but North Texas scored three in the fourth to tie the game.

CSUB starter Sammy Rodriguez (Salinas HS) slammed the door for the next six innings, fanning 10 batters to keep CSUB in the game, but North Texas starter Brittany Simmons blanked CSUB over the final eight frames. Finally, in the 11^th, two 'Runner errors and a passed ball opened the floodgates in a four-run inning that decided the affair.

Oklahoma, meanwhile, scored six in the second inning and five more in the third to put its opener away early. CSUB broke up the no-hit and shutout bids in the fifth inning when freshman shortstop Amy Ricciardi (Chino Hills/Ayala HS) followed Lee's leadoff walk by ripping her first collegiate home run to deep left field.
