IRVINE - Junior Zoe Katz gave reason to believe Campbell Hall's girls tennis team would avenge its earlier loss this season to University High of Irvine in the postseason rematch Thursday with the Trojans. The Vikings' top singles player missed that contest, won by University on games, because of an injured wrist. She was back in the lineup for the Southern Section Div. I semifinal showdown, but it didn't prevent the hosts from another streak-stopping performance. The fourth-seeded Trojans upset No. 1 Campbell Hall 11-7 to reach their first Div. I girls' tennis final. The loss ended two-time defending Div. I champion Campbell Hall's playoff winning streak at 13 matches and prevented the Vikings from reaching their sixth final in nine seasons. Campbell Hall's last playoff loss came to Peninsula 10-8 in a Div. 1 quarterfinal match Nov. 18, 2008. University's Sept. 20 victory over Campbell Hall (16-2) ended the Vikings' 38-match winning streak. Since it came on games and without Katz playing, it gave Campbell Hall the opportunity to payback the Trojans on Thursday. The chance was all but over by the time the second round ended. University (20-2) held an 8-4 advantage, sweeping all six doubles sets. The Trojans ended up winning all nine. The trip to University was Campbell Hall's third one to Orange County in four days. On Monday, the Vikings visited Santa Margarita and on Tuesday were at San Clemente. "We felt good about it," Campbell Hall coach Steve Kuechel said. "Maybe we were tired from all the bus rides. They outplayed us and deserved to win. When you don't get any doubles, you're not going to win any match." Valerie Thong and Conner Calabro hadn't lost all season at No. 1 doubles. The pair rallied back in the opening round in the first meeting with University to win, but they couldn't overcome a large deficit this time and fell to Krystal Lai and Kyla Scott, 6-2. When Yuki Asami beat Alyza Benotto, 6-4, it gave University a 4-2 lead after the first round. Kyra Scott, who played doubles in the first meeting but was moved to No. 1 singles Thursday, recorded a key win in the second round when she beat Alexis Pereira 6-2. That put the Trojans ahead 8-4 and essentially sealed the victory. University was up by 15 games at the time. "I didn't think we were winning today," University coach John Kessler said. "Not with them having Zoe back and with how we played the last time. I know the trips had to take a wear and tear on them, but this is the biggest win in University girls' history." Katz ended up sweeping her sets, 6-2, 6-1, 6-2. She's one on of seven underclassmen returning next season as only seniors Valerie Thong and Priya Amritraj leave. The others returners include Benotto, Pereira, Calabro, Caroline Hull, Joy Kim and Ifeoma Kuchler. "It's hard to three-peat, especially when you lose girls like Sarah Lee and Sabrina Santamaria," Kuechel said. "It was disappointing because I thought we had a good chance at winning, but it wasn't meant to be."
