A renovated Husky Ballpark record crowd of 2,413 saw the Cougars (16-28, 9-16 Pac-12) erase a 3-1 deficit by sending 11 batters to the plate against Noah Bremer and Alex Nesbitt.
The inning began with Ty Johnson reaching safely on an error by Chris Baker. Patrick McGrath singled to put runners at first and second. Mason Cerrillo struck out attempting to sacrifice but then Weston Hatten singled to load the bases and Cameron Frost walked to force home Johnson for a 3-2 score. Jack Strunc drove home McGrath with a single to knot the game at 3.
Matheny batted next and lined a 1-1 pitch to right center to score Hatten and Frost for a 5-3 Cougar lead. Trek Stemp greeted Nesbitt with a run-scoring double and Johnson plated two more runs with a single to right.
Bremer (4-5) got charged for seven runs, five earned, in five and a third innings. He allowed eight hits and walked two while striking out seven.
The Huskies (27-17, 13-9 Pac-12) took a 2-0 lead in the bottom of the second inning.
Joey Morgan and Duncan Hendrickson both walked on four pitches from Damon Jones. John Naff sacrificed the runners up a base. With two outs K.J. Brady beat out an infield hit to score Morgan and A.J. Graffanino followed with a ground single to left to score Hendrickson.
After the Cougars got a run back to make it 2-1 in the top of the third, courtesy of a balk by Bremer, the Huskies made it 3-1 in the fourth when Hendrickson got hit by a pitch, took second on a balk, moved to third on a single by Naff, and scored on a sacrifice fly to center by M.J. Hubbs.
The Cougars completed the scoring in the ninth on a run scoring triple by Matheny, who finished his night 3 for 5 with a run scored and three runs batted in.
Colby Nealy (1-2) retired the only two batters he faced in the bottom of the fifth to get the win.
The to teams continue the Apple Cup of baseball on Saturday at 4 p.m. at Husky Ballpark. The pitching matchup will feature a pair of right handers, Joe DeMers for the home team and Ian Hamilton for the visitors.
