SEATTLE, Wash. -- Early offense helped Arizona State to a 5-4 win against No. 11 Washington (36-14, 7-13 Pac-12) on Sunday. The No. 3 Sun Devils clenched the Pac-12 series sweep, their fourth of the season and most by the team in the Clint Myers era.

In the first inning, ASU (42-5, 14-2 Pac-12) busted open a 3-0 lead with RBI hits by Annie Lockwood, Haley Steele and Amber Freeman. Lockwood, who went 2 for 3, is now sixth all-time at ASU in RBI with 164, 17th in doubles (22) and 20th in hits (170).

Washington answered in the bottom of the inning with two runs brought in by Kylee Lahners, diminishing ASU’s lead to 3-2.

Katelyn Boyd helped the Sun Devil offense continue dealing with a double to left center in the second, pushing the score to 4-2 as Bailey Wigness came home on the play. Her double moves Boyd two away from the top of the ASU career record book where Kaitlin Cochran’s 54 lead the way.

A Bethany Kemp infield single in the fifth helped the Arizona State cause, bumping the score up to 5-2 when Steele scored from second.

In the bottom of the sixth Shawna Wright homered to left center for the Huskies to again chip at ASU’s lead, which dropped to 5-3. UW scored a late run in the bottom of the seventh via a Wright single, but it was not enough as the Sun Devils held on for a one-run victory.

Dallas Escobedo picked up the win and is now 16-4 on the year. Kaitlin Inglesby (18-9) garnered the loss after 1.0 innings in the circle.
