The 2018 NCAA women's soccer tournament got underway Friday with Arizona, Stanford, UCLA, USC and Washington State representing the Pac-12 in the postseason. All five teams won in the first night of tourney action, advancing to the second round.

Here's how it all went down:

USC 6, Long Beach State 0

The Trojans wasted no time getting their NCAA Tournament ride off to a fast start. USC built up a 2-0 halftime lead behind goals from Natalie Jacobs and Alea Hyatt. Then, the rout was on. USC scored three times over the first 10 minutes of the second half to bring the lead to 5-0. At night's end, the home team outshot the visiting team 28-8 as the Trojans had to make just two saves over the 90-minute contest.

USC also had six different goal scorers on the day, matching a new season high. The Trojans advance to face either LSU or Boston University on Thursday, Nov. 15.

UCLA 5, San Jose State 0

Don't hurt 'em, Bruins! UCLA began its postseason with a bang Friday night, scoring four goals in the first 31 minutes of the match against the Spartans. Sophomore Ashley Sanchez netted two of those first-half goals, bringing her scoring tally to 10 on the season. The lone second-half goal came via a Marley Canales penalty kick in the 48th minute, marking the sophomore's first strike of the season.

UCLA's second-round match will be Nov. 15 against the Minnesota Gophers, who took down Auburn in the first round, 2-0.

Arizona 3, Denver 0

It was more of a slow boil for the Wildcats, but they sent Denver back home Friday night after an electric second half. Arizona dropped three goals on the Pioneers in a 21-minute span post-halftime, starting with senior Kennedy Kieneker's cross in the 53rd minute to get on the board. Amanda Porter kept things rolling just a few minutes later with this head-snapping free kick:

Arizona is set to play Tennessee in the second round on Thursday, Nov. 15.

Washington State 5, Montana 1

Washington State reached five goals in a game for the first time this season, unleashing the Cougs’ scoring power on the Montana Griz for a first-round win Friday night in Pullman. Their offensive effort was nicely distributed, employing a different scorer for each goal on the night. Check out Hailey Smith’s deal-sealer in the second half to make it 4-0:

Washington State takes on Georgetown or Central Connecticut State on Thursday, Nov. 15.

Stanford 3, Seattle U 0

Civana Kuhlmann did the heavy lifting for the Cardinal Friday night in Palo Alto, scoring two of her team’s three goals on the night. Well, kind of. Kuhlmann definitely nailed this one 13 minutes into the match, giving Stanford the 1-0 lead:

But the second one is up for interpretation. Shortly after halftime, Kuhlmann sent in a shot that ended up deflecting off a Seattle U player and into the net, making it 2-zip off the own goal. Carly Malatskey finished off the Redhawks in the final minute of the match, netting her first goal of the season. Stanford moves onto face Clemson or Ole Miss on Thursday, Nov. 15.
