UO release - OKLAHOMA CITY — They surrendered the driver's seat in regionals, and needed extra innings to win their Super Regional opener.  This postseason has proven that the Oregon softball team knows how to weather tough battles. The Ducks have another on their hands at the Women's College World Series, after a heartbreaking loss to open the tournament Thursday, 4-2 to UCLA at Devon Park.  The Ducks (53-9) scored the game's first run in the third inning, then tied it back up at 2-2 in the top of the seventh. In the bottom half, the Bruins hit their second two-run homer of the night for a walk-off win that has Oregon one loss away from seeing its season come to an end.  "This group is so good at bouncing back," said senior shortstop Paige Sinicki, who doubled and scored in the seventh to extend the game. "We've shown it all year. And so I'm excited to see what we do tomorrow."  Oregon will play an elimination game against Mississippi on Friday at 6:30 p.m. PT. The winner will earn an off day Saturday before returning to the field Sunday, while the loser will have played its last game of the year.
