Washington (7-19) struck first in the bottom of the fourth inning as Eric Peterson drew a two-out walk and scored on a double by Chase Anselment. Seattle U tied the game at 1-1 in the top of the fifth inning when Jace Sloan hit a two-out double, advanced to third on an error by Washington pitcher Zach Wright, and scored when Wright threw a wild pitch.
Josh Kutz led off the top of the seventh inning with a home run to left field. Sloan followed with his second double of the game, and a Cullen Hendrickson single put runners on first and third with nobody out. After a pitching change, Marcelino Morales laced a single up the middle that drove in Sloan and, after a sacrifice bunt put runners on second and third, Hendrickson scored on a sacrifice fly by Nate Roberts.
The Huskies answered back in the bottom of the seventh inning, as Ty Afenir reached on a throwing error by Kutz, Spencer Rogers singled, and Joe Meggs was hit by a pitch to load the bases. A sacrifice fly by Jacob Lamb drove in Afenir, and Rogers hustled around third and scored on a ground ball hit by Troy Scott to bring Washington within one at 4-3.
Blaine Jones came on in the bottom of the ninth attempting to save the game, but singles by Lamb, Scott, and Peterson allowed the Huskies to pull into a 4-4 tie. Peterson took off for second base and Jones threw to Trent Oleszczuk, who fired a throw home to catch Scott attempting to steal home with the winning run, forcing extra innings.
With one out in the 10th inning, Doug Kincaid walked, and Matt Comer earned an infield single. Michael Tevlin followed with a single through the right side of the infield that scored Kincaid, and Hendrickson drove in Comer with a sacrifice fly for an insurance run. Jones came back out for the 10th inning and gave up a leadoff walk to Brendan Gardner-Young, but B.K. Santy lined into a double play and Reggie Jones popped out to end the game.
Eric Yardley earned the start for Seattle U, pitching 4 1/3 innings and allowing just three hits, two walks, and one run in the longest outing of his career. Conor Spink pitched three innings of one-hit ball before yielding to Bryan Dalton who earned two strikeouts in his brief tenure on the mound.
"We were resilient tonight and did a really good job of preparing for this game," head coach Donny Harrel said. "Eric gave us the start we needed and we got ahead, but they pushed back. What a complement to our club to not allow that ninth inning to get them down and deter us from winning. We came back strong in the 10th and got the inning from Blaine that we needed."
Sloan finished the game 3-for-4 with two runs scored and a walk, while seven other Redhawks earned one hit apiece in the game. Rogers picked up two hits for the Huskies, who left 11 runners stranded on base.
