PROVO — With a 4A championship on the line, Timpview and East staged the sort of classic head-to-head duel everyone expected.

Ultimately, Timpview had just enough depth to prevail. The T-Birds derailed East's bid for a third straight 4A girls swim title, scoring 367.5 points to take home top honors at BYU on Saturday night.

East finished second with 301 points. Murray placed third with 233 points.

It didn't take long for the 4A meet to evolve into a two-team race.

Isabela Castro scored a pair of second-day victories for Timpview. She won the 500 freestyle with a time of 5:08.46 and took the 100 backstroke in 59.65 seconds. Meagan Stone added another win in the 100 fly, finishing in 57.66 seconds. And the T-Birds claimed top honors in the 400 freestyle relay.

For the Leopards, Winifred Lau claimed the top spot in the 100 freestyle with a time of 54.09 seconds and the 200 freestyle relay team emerged victorious.

In all but one of those races, if Timpview or East claimed first place, the other team took second.

"We knew that coming in, that's exactly how it was going to score out," T-Bird coach Brian Sorensen said. "We knew it was going to go back and forth today."

For Castro, all of those individual and relay titles capped her only season at Timpview in a satisfying manner. But the team title felt equally satisfying after hearing so much undue emphasis put on her and fellow Brazilian Julie Moraes being with the T-Birds.

"This team is not just me and Julia," Castro said. "Every single girl can swim. They're fast. We're a team. Not Brazil. Not anything. We are the Timpview team."

Sorensen hopes this state title will have a long shelf life as he continues to build the T-Bird swimming program. The program numbers aren't quite where he wants them, but Sorensen feels confident he can attract more swimmers who want to be part of a good thing.

"Other kids in the school have got to see the success of the program before they take that jump and want to join the team," Sorensen said.

Mountain Crest's Meghan O'Very was the only swimmer to break through the title stranglehold by East and Timpview. O'Very finished in 1:07.77 to win the 100 breaststroke, edging out Harper who finished in 1:07.77.
