Defending champion Gunn completed the first half of the SCVAL De Anza Division schedule undefeated following a 16-12 victory over rival Palo Alto on Tuesday in boys' water polo action.
"That was a big win for us," said Gunn coach Matt Johnson, who guided the Titans to the regular-season and division playoff title last season while beating his twin brother and Paly coach, Brandon, three times.
Calder Hilde-Jones paced the Titans (6-0, 8-5) with a season-high seven goals, many coming from his two-meter position. Fellow senior Christian Znidarsic, another holdover from last year's championship team, added four goals for Gunn.
The Titans overcame a slow start and a 5-3 deficit in the first period, taking the lead for good in the second half at 7-6 following a goal by Hamilton. The Titans pulled away for good in the third period with a 5-1 scoring splurge.
"The guys stuck to the game plan, even though things weren't going our way early," Johnson said. "We just stepped up the defense."
Lucas Novak paced the Vikings (4-2, 5-10) with three goals. Ray Zhao, Kevin Bowers, Winston Rosati and Andrew Josefov all tallied twice for Paly.
Gunn holds a one-game lead over second-place Mountain View (5-1), which handed Homestead a 14-9 loss on Tuesday. The Titans handed the Spartans their only loss.
In Concord, Menlo School won for the 11th time in 12 matches as senior Nick Bisconti poured in seven goals in a 17-11 nonleague victory over host De La Salle on Tuesday. Spencer Witte came up with 12 saves in goal for the Knights while Andreas Katsis added four goals.

Gunn wrapped up the first half of the SCVAL De Anza Division season with a 7-5 victory over visiting Palo Alto on Tuesday night.
The defending champion Titans moved to 6-0 in league (11-3 overall) while the Vikings fell to 4-2 (7-7) despite three goals from senior Tess van Hulsen.
Gunn pulled away to a 5-2 halftime lead before Paly put on a furious rally in the second half and got to within one goal after van Hulsen scored her third goal late in the fourth period. Bianca Batista, Zoe Banks and Nia Gardner all scored twice for the Titans while goalie Sam Acker was solid in the cage.
