The victory in front of a crowd of 959 evened the Mountain West series at 1-1 with the finale on Sunday at noon. The Wolf Pack, which had won three games in a row going into Saturday's game, fell to 6-8 overall and 3-5 in league play San Diego State is now 10-4, 3-2.
The Wolf Pack, though, jumped out to a 2-0 lead after two innings. Kyle Hunt led off the first inning with a home run off Aztecs' starter Bubba Derby and freshman Trenton Brooks led off the second with another home run.
The Pack had hit just two home runs over its first 13 games. The home runs were the first of the season for both Hunt and Brooks. The homer for Hunt was just his second in his three-year Pack career. His other home run came on March 26, 2012 against UC Davis.
Wolf Pack starter Barry Timko, though, ran into trouble in the third inning as the Aztecs scored three times to take a 3-2 lead. Timko, who took the loss to fall to 2-1 on the year, lasted just 3.1 innings and allowed five hits, three walks and four runs.
Timko's relief didn't fare much better. Mark Nowaczewski hit three batters and surrendered seven hits, three walks and four runs in 3.2 innings. Austin Dick gave up three hits and two runs in his one inning of work.
The three Pack pitchers combined to throw just 81 of their 148 pitches for strikes.
Derby earned the victory to improve to 2-0. The former closer went five innings and allowed six hits and three runs. Three Aztec relievers -- Brandon Thomas, Justin Hepner and Michael Cederoth -- combined to no-hit the Pack over the final four innings.
San Diego State's top seven hitters combined to go 14-for-25 with nine runs scored and 10 RBI. All seven of them had at least one RBI with Andrew Brown (3-for-5) leading the way with four.
The Pack added runs in the sixth and eighth innings. Bryce Barger drove in the run in the sixth on a ground out and Jay Anderson did the same in the eighth.
The Wolf Pack did not commit an error for just the second time this season. The Pack, which committed 22 errors in its first 10 games, has made just two errors in its last four games.
The Pack is now 1-4 at Tony Gwynn Stadium since joining the Mountain West last year.
