The Trojans struck first, securing the doubles point in a battle that went to a tiebreaker. Stanford and USC traded wins at No. 1 and No. 2, with Tom Fawcett and Axel Geller getting the win for the Cardinal. USC's Daniel Cukierman and Tanner Smith sealed the point at No. 3, with a 10-8 win in the tiebreaker.

The win improved the Cardinal to 16-2 overall, matching its best start in 16 seasons. It's Stanford's first win in Los Angeles against either USC or UCLA since 2010 and the Cardinal's first win against the Trojans in Los Angeles since 2009. Stanford is now 3-1 in Pac-12. USC moves to 12-6 overall and 3-1 in the conference.

Fomba, who also clinched a 4-3 victory at No. 20 Arizona State earlier this month, recorded his third clincher of the season. All three have come against top-20 opponents as the graduate student also lifted the Cardinal to the win over No. 12 Baylor in the ITA National Indoor Championships.

Stanford erased a 2-0 deficit and was on the doorstep of a fifth straight win as David Wilczynski had match point when Fomba clinched it.

Graduate student Eric Fomba delivered his second clincher in Stanford's four Pac-12 matches as the Cardinal rebounded from losing the doubles point with four wins in singles to down No. 14 USC, 4-2, Saturday afternoon at Marks Stadium in Los Angeles.

The win for the Cardinal was its second over USC this season. Stanford defeated the Trojans, 6-1, in February on The Farm.

All eyes went to the No. 4 and No. 5 matches. Fomba (No. 4) and Wilczynski (No. 5) both dropped the first set of their matches, but each stormed back with second-set wins. They continued their momentum with multiple-game leads in the third set. Fomba sealed it first with the 6-2 victory in the third set. Wilczynski was up 5-1 in the third set with match point coming up when Fomba clinched it.

In a top-10 matchup, Fawcett, ranked No. 10, and No. 9 Brandon Holt of USC staged a three-set battle. The Cardinal senior rebounded from an opening-set defeat with a pair of 6-3 frames to win it and push Stanford ahead for the first time in the match.

Geller got it started with a straight-set win at No. 2 and Sameer Kumar followed moments later with a straight-set victory at No. 3.

The Cardinal, which has not lost since Feb. 24, continued its dominance in Pac-12 play by recording its third shutout against conference competition.

Stanford (11-3, 5-0 Pac-12) quickly dispatched of Arizona (9-10, 0-5 Pac-12), securing the doubles point before racking up four convincing singles victories, the final two of which finished simultaneously.

Stanford powered its way to a seventh straight win and third consecutive shutout, blanking Arizona 5-0 on Saturday to sweep its desert road trip.

The clincher came from Emily Arbuthnott, who won 6-1, 6-0 at the No. 4 spot. During the clincher, Michaela Gordon had match point in progress and coasted to a 6-2, 6-1 win at the top spot of the lineup.

Competing in her third match since returning from injury, Melissa Lord contributed a 6-1, 6-3 victory at the No. 2 spot.

For the second straight day, Stanford captured the doubles point on the strength of wins at Nos. 2 and 3.
