SURPRISE, Ariz. -- Hawai`i Hilo advanced to the quarterfinals for the first time since 2012 and earned its first win in the winners' bracket since 2009 by upsetting No. 8 seed Concordia 4-1 on Wednesday afternoon at the Surprise Tennis & Racquet Club, while Fresno Pacific, Academy of Art and Cal State LA all advanced with wins as well in the first round.

The Vulcans' lower half of the lineup was dominant on the afternoon with Hikari Osaki, Nanami Okamoto and Hannah Highsmith all winning in straight sets in singles. Highsmith was the one to clinch the victory with a 6-2, 7-5 win at No. 6 singles. 

Julia Barden also played a key role in winning the doubles point alongside her partner Okamoto. The Vulcans' No. 1 duo was locked in a tight battle long after the other two doubles sets had been split, and Okamoto and Barden came through with a 7-5 win to earn the first point of the day. Maya Arksey won the lone point for the Eagles, winning 6-3, 6-1 at No. 2 singels, while the Eagles had won the first set in each of the unfinished matches.

Cal State LA won its match 4-2 with Chelsey Ruiz providing the clinching win against Dominican. This was a rematch from the 2018 PacWest Championships, where Dominican pulled off a historic 5-4 upset as the No. 11 seed against No. 6 Cal State LA. The Penguins put pressure on the Golden Eagles, but Ruiz's 6-1, 6-4 win sealed the victory.

The Golden Eagles earned the doubles point quickly and had a fast start in singles with Noa Davica and Berta Acero each winning 6-1, 6-0 at No. 2 and 3 singles, respectively. That quickly gave Cal State LA a 3-0 lead, but the Penguins fought back with Julia Rydel winning at No. 4 singles, 6-4, 6-4, while Ghada Alajeely won at No. 6 singles 6-1, 6-1. The unfinished match at No. 1 singles was locked in a tiebreaker at 7-7 in the second set when the match was clinched. Audrey Rafols won her first set, 6-1.

No. 5 seed Fresno Pacific had to work hard to get its spot in the quarterfinals against No. 12 Colorado Mesa. Sanne Brull clinched the match for the Sunbirds, 6-0, 6-3 at No. 5 singles after Leah Falentin and Alice Di Matteo won at No. 2 and No. 3 singles. All three unfinished matches remained close, including Macy Richards winning the lone set for the Mavericks.

Maria Casucci played arguably her best match of the season for the Urban Knights, winning 6-3, 6-2 at No. 2 singles to help Academy of Art advance against an injury-depleted MSU Denver team. Julia Ortega completed the victory with her 6-1, 6-0 win at No. 4 singles. At No. 1 singles, Isabel Heras took a set off Sofia Ragona, but the Urban Knights' No. 1 was in the lead late in the second set when the match was called.
