Clovis High's boys water polo team showed off its resolve Wednesday.
The Cougar girls, meanwhile, displayed the dominance that has produced consecutive championship seasons.
Both are headed to the Central Section Division I finals.
Connor Cookingham's goal on the first possession of sudden victory gave the second-seeded Clovis boys an 11-10 win over No. 3 Clovis North.
The Cougars face top-seeded Buchanan at 11 a.m. Saturday at Clovis West for the title.
"This is huge," Cookingham said. "We're one more step from that championship. It was a rough game, but we pushed through."
The top-seeded Clovis girls followed that by riding Hannah Harvey's five goals to a 16-10 victory against No. 5 Clovis North, setting up a rematch of the past two finals with No. 2 Clovis West at 1 p.m. Saturday at the Cougars' pool.
"This is our reward for how hard we've worked this year," Harvey said.
In one of the most riveting boys games of the season, Clovis North (24-9) forced the sudden-victory period when Carson Ivancovich scored off a quick pass from Colton Privett as time expired in the second overtime.
Ryan Perry won the ensuing sprint to give Clovis (24-7) the ball first.
The Cougars didn't give the ball back, drawing two ejections on its possession, with Cookingham taking advantage of the second man-up situation by firing the winner past Broncos goalkeeper Andrew Wettstead.
"The first kickout didn't go so well, but thankfully we drew another one," said Cookingham, who finished with a game-leading four goals. "I had an open shot, so I took it. There was no one on me."
Clovis -- which had defeated Clovis North twice previously -- faced a four-goal deficit early in the third quarter. But after switching from a drop to a pressing man-to-man defense, the Cougars got three steals from Perry as they cut the gap to 7-6 entering the fourth.
"That shocked them a little bit," Perry said. "They had to change their game."
Clovis took its first lead of the game on Cookingham's 5-meter penalty with 2:20 left in the first overtime.
Clovis North countered on Austin Radke's goal. The Cougars again went ahead first in the second overtime on Nick Alexander's only goal of the game, a score matched at the buzzer by Ivancovich.
"We all rallied together," Perry said. "We're exhausted, but it's worth it to get to Saturday."
Clovis North also held a halftime lead -- 6-5 -- in the girls game against the two-time defending D-I champions.
But Clovis (26-4) exploded for 11 second-half goals to pull away.
"It's never easy when you get this far along in the season," Cougars co-coach Evan Baird said. "Teams you have beaten play up because it's potentially their last game."
After missing six of eight shots in the second quarter, Clovis responded to Baird's halftime pep talk by making 7 of 9 shots in the third.
Catie Mahnke's goal with 3:59 left put the Cougars ahead for good.
"Our team always has its troubles shooting," said Harvey, who had one of the third-quarter scores. "Once we miss a couple, we are mentally unstable. It takes our coach talking us back into the game. And once we start making shots, our defense gets motivated to make steals so we can score more. It's definitely a team effort."
Clovis North (23-11) got within 14-10 following Katelyn Fairchild's sixth goal of the game in the fourth quarter, but that's as close as the Broncos would get.
"We weren't finishing our shots early on," Baird said. "And because of that, we weren't transitioning well. After halftime, they started finishing their shots and had fun."
Boys: Buchanan 15, Clovis West 6
Bears' goalkeeper Taylor Smith shut down the two-time defending champion Golden Eagles with 14 saves in a rematch of last year's D-I final.
Buchanan (27-4) jumped out to a 3-0 lead in the first and never looked back. The Bears essentially put the game away in the third by outscoring Clovis West 5-0.
Brent Teraoka led Buchanan with four goals. Adam Palecek and Max Cusator scored three times each for the Bears.
Ting Williams had four goals to lead fourth-seeded Clovis West (9-22).
Girls: Clovis West 13, Sanger 3
Mary Brooks outscored the sixth-seeded Apaches all by herself with six goals to power the Golden Eagles into the finals for the 16th time.
Clovis West (23-5) also received two goals apiece from McKenna Fife, Charlee Starkweather and Sarah Snyder, and eight saves from Michelle Reed.
Sanger (25-8) got two goals from Jillian Hatch.
