SPOKANE, Wash. — Gonzaga baseball battled back to tie the score late, but San Diego came up with the timely offense to win 4-2 in a 12-inning affair at Patterson Baseball Complex and Coach Steve Hertz Field.

After Gonzaga (10-12, 3-4) tied the score at 2-2 in the eighth inning, San Diego (18-8, 4-3) mustered two runs in the 12^th for the series-opening win.

Gonzaga was solid on the mound, getting a quality start from Mason Wells with 6.2 innings of work. He allowed just two runs on five hits with six strikeouts and four walks. Taylor Davis threw 1.1 innings of scoreless relief, and Alek Jacob threw the final 4.0 innings. Jacob pitched well, but took the loss despite giving up just two runs on four hits with five strikeouts.

The top three spots in the GU lineup reached base a combined 10 times in the game with eight walks and two hits. Ernie Yake and Guthrie Morrison each earned three walks. Brett Harris and Austin Pinorini each had a hit and an RBI in the game.

The Toreros got on the board first with two runs in the fourth inning and held the Gonzaga offense scoreless until the eighth. USD starter Chris Murphy left the game after seven scoreless innings, and GU got to the bullpen.

Gonzaga drew three walks to start the inning, loading the bases with nobody out. After a strikeout, Austin Pinorini brought home one on a groundout and then Brett Harris hit an infield single to tie the score.

GU threatened again in the ninth, leaving two on base, and again in the 11^th, leaving the bases loaded.
