Patmon, who scored the game-tying run after a leadoff triple in the sixth, crushed the first pitch she saw in the seventh to send the Np. 16 seed Ducks to a 10-7 comeback win over Stanford in the Eugene Regional final Sunday night at Jane Sanders Stadium.

Stanford was held to just two hits after Economides’ second home run as Oregon left-hander Staci Chambers relieved starter Lyndsey Greir and threw 4 1/3 scoreless innings. Elise Sokolsky recorded the final out in the top of the seventh inning.

The Ducks defeated Stanford, 15-5, to force a winner-take-all finale at the Eugene Regional at Jane Sanders Stadium.

The Ducks (48-8) lost for the first time in Regional play at home in the most lopsided loss of the Melyssa Lombardi era. The Cardinal (41-11) advance to Sunday’s regional final at 3:30 p.m. Oregon plays the winner of Weber State and Binghamton in an elimination game at 6 p.m., with the winner advancing to the Regional final.

Cardinal sets a postseason school record with four homers in a game as Joie Economides, Allie Clements, River Mahler and Jade Berry go deep.
