Six scoreless minutes after halftime became three Cal State San Marcos goals in seven. Cisco Avila converted a penalty and scored again from open play before Blake Haseyama finished the burst, sending the Cougars past Vanguard 3-0 Thursday in Costa Mesa.
The first half had been balanced and restrained. Each team took four shots, while Vanguard produced the only attempt on target. Neither side scored. CSUSM returned from halftime with the same total as the Lions and no statistical warning that the match was about to separate.
An off-ball foul in the middle of the penalty area supplied the first opening. Avila drove the 48th-minute kick low into the bottom-right corner. The finish was his first goal of the season and changed Vanguard's obligation immediately: the Lions could no longer wait for the match to offer space.
Avila doubled the lead in the 54th. After a CSUSM corner, he collected possession outside the top of the box and shot into the right side. The second goal did not require another penalty or assist. It came from maintaining the attack after the initial restart failed to produce a direct finish.
Just over one minute later, the Cougars struck again. Andrew Valencia sent a long pass from deep in CSUSM territory to Haseyama beyond midfield. Haseyama carried into the box and rolled a low shot into the left side. At 55 minutes, a match that had been 0-0 at 47 was effectively out of Vanguard's reach.
San Marcos took nine second-half shots to Vanguard's four and earned all three corners after the break. For the match, the Cougars led 13-8 in shots, 4-2 in corners and 54%-46% in possession. Vanguard held a 4-3 edge in shots on goal, an unusual line created because every CSUSM attempt on frame became a goal. The Lions placed three attempts on target after halftime, so CSUSM still had to defend once the scoring burst ended. The defense protected the resulting margin.
That perfect conversion is not a rate a team can treat as repeatable. It does show how completely the Cougars used their best stretch. Avila's two goals were his first of the season and raised his CSUSM career total to seven. Haseyama's finish was his second this year and fifth for the program.
The win moved Cal State San Marcos to 2-1 and produced its largest margin in seven meetings with Vanguard dating to 2006. The Cougars took a 4-3 lead in the all-time series and improved to 4-1 against the Lions in Costa Mesa. More important to the current season, they paired the scoring burst with their second shutout in three matches.
CSUSM has nine days between the Vanguard result and a Sept. 12 match at Biola. The break offers time to distinguish a productive mechanism from an exceptional outcome. Winning the second ball after a corner and sending an early pass into Haseyama's path can be trained and repeated. Scoring on all three shots on goal cannot be assumed. For seven minutes Thursday, both aligned.
