South High's Whitney Williams is the lone defending champion at this week's Cook Inlet Conference tennis championships, which begin Thursday at The Alaska Club North.
Williams is the top seed in girls singles.
Other top seeds include West's Reed Lekander in boys singles, South's Daniel Frentzel and Justin Wolfe in boys doubles, West's Katie Brown and Alli Haynes in girls singles and South's Palden Flynn and Bryce Foster in mixed doubles.
Lekander was last season's top seed as well, but he lost in the finals to South's Eddie Lewis, who has graduated.
Also back as a top seed is Brown, who was seeded first in girls doubles with a different partner last season but wound up finishing second.
South and West are the defending co-champions. They shared last season's team title with 17 points apiece.
Dimond in front
With less than two weeks remaining until the start of the Cook Inlet Conference flag football playoffs, defending champion Dimond is in good position to secure the top seed.
The Lynx are 10-0 and three games ahead of second-place South, which suffered its second loss to Dimond last weekend. The Wolverines (7-3) did manage to score two touchdowns in the 19-14 loss, more than any other team has scored against Dimond this season.
The Lynx, who have outscored opponents 332-32 and pitched six shutouts, are riding a 27-game winning streak after going 17-0 on their way to a third CIC title last season.
South had won five straight before a pair of losses last week. The Wolverines rebounded from the losses with a win over East on Tuesday and sit two games ahead of Service and West, which are tired for third with 5-5 records.
