The Portland Pilots came from behind Friday afternoon to stun Pepperdine 7-6 in their West Coast Conference opener at Joe Etzel Field.

UP second baseman Riley Henricks scored on a wild pitch in the bottom of the 10th inning to give the Pilots the victory.

Portland had trailed 5-0 after three innings and was down 6-3 with two out in the bottom of the eighth. Freshman Turner Gill's two-run single scored Henricks and Ben Grubb to pull the Pilots within 6-5. Then pinch runner Sam Westerndorf got to third base on a wild pitch, before scoring the tying run on a double by Matt Mardesich.

The Waves loaded the bases in the ninth, but Portland reliever Chris Dennis ended the inning with a strikeout. Dennis (1-2) worked two scoreless innings and picked up the win.

The Pilots, who had lost five in a row, improved to 11-15 overall.

Pepperdine slipped to 14-15.

The series will conclude Saturday with an 11 a.m. doubleheader.
