Beck was marvelous in his stint, scattering five hits and striking out five to earn his fourth win of the season against a pair of losses. Beck made way for Jack Little in the eighth, who earned his Pac-12-leading 11th save of the season. Little surrendered his first run of the season in the eighth, pitching out of a jam with runners on second and third with one out.

"Tristan really battled tonight, and you saw what kind of pitcher he is once he settled in a little bit," said Stanford coach David Esquer. "I thought Tristan and Nico Hoerner really stepped up tonight, and once again Stowers continues to be a big bat in the middle of the order for us."

Stowers gave the Cardinal (25-5, 7-3) a 1-0 lead in the second inning. Stowers hit the first pitch he saw over the fence in right field for his fifth home run in eight games.

Tristan Beck threw seven shutout innings, Kyle Stowers hit his seventh home run of the season and it was good enough for host Stanford to beat Arizona State, 3-1, in a Pac-12 Conference baseball contest Friday night.

Aria Fischer had two goals and No. 1 Stanford was within one midway through the third quarter, but No. 2 USC scored three unanswered to pull away and beat the Cardinal 8-5 at Avery Aquatic Center on Friday night.

The Cardinal plated an insurance run in the bottom of the seventh with Beau Branton scoring on a bases-loaded wild pitch. Tim Tawa reached base three times, and Branton, Andrew Daschbach and Maverick Handley each had one hit.

Stanford doubled its lead in the third. Nico Hoerner's triple down the right-field line scored Tim Tawa from second. Hoerner was outstanding at shortstop, making several highlight-reel plays, including a tricky 6-4-3 double play in the sixth.

"You know it had to happen at some point," said Esquer of his closer, who pitched his first 21 1/3 innings of the season without allowing a run. "We've thrown Jack into a lot of different situations and tonight was another example of what a great pitcher he is."

Klass was kicked out with the clock winding down in the third period and USC called a 30-second timeout to set up a play which resulted in a goal from Brianna Daboub with four seconds on the clock.

The Cardinal would go cold down the stretch, unable to find a goal until Fischer fired one in with just 12 seconds left and the game already in hand for USC.

Hayley McKelvey answered right back for USC on its next trip down the pool to end a more than 13-minute scoreless drought for the Trojans and Aria Fischer rattled the cage on Stanford's ensuing possession to make it 5-4 with 6:27 on the clock in the third.

The Trojans (18-1, 3-0 MPSF) scored the game's first three goals and raced out to a 4-1 lead before Stanford (14-1, 1-2 MPSF) started to surge back. The Cardinal's sixth power play resulted in its second goal late in the second quarter on a skip shot to the near post from Kat Klass to make it 4-2. USC was whistled for a common foul early in the third and with three seconds on the shot clock Makenzie Fischer fired off a shot from beyond five meters on the restart to pull the Cardinal within a goal.

Freshman Ali Baiocco had five ground balls, while Allie DaCar made seven saves and scooped up a team-high eight ground balls.

Both teams had several chances in overtime before the Buffaloes ended it. The loss snapped an eight-game winning streak for the Cardinal, dating back to a March 9 defeat at Colorado.

The visiting Buffaloes scored the game-winner with 11 seconds remaining in the first overtime to move into sole possession of first place in the Pac-12. Colorado (10-4, 7-1 Pac-12) is now one game ahead of Stanford (11-4, 6-2) in the conference standings with two games remaining.
