HONOLULU - Three full days at a beachfront hotel on Waikiki, and Kaleb Tarczewski still hasn't touched the water.

"I look down on it from my balcony, but that's about it," Tarczewski said.

Maybe tonight. Maybe never. It doesn't matter.

Tarczewski and the No. 4 Wildcats are having their fun on the court, cruising to a surprisingly convincing 69-50 win over Miami on Sunday night in the semifinals of the Diamond Head Classic.

Tarczewski had 13 rebounds while UA crushed the Hurricanes on the boards 46-20 to advance to the championship game against No. 18 San Diego State on Tuesday at 7:30. The Wildcats are 11-0.

"We're out here for one reason, and that's to win the championship," Tarczewski said after Sunday's game.

The Wildcats not only dominated on the boards but also hit 8 of 18 three-pointers, with a 6-of-11 performance in the first half, all while negating their usual turnover problems.

Arizona had 16 turnovers, however, continuing a trend in which they had 18 turnovers in a first-round game with East Tennessee State on Saturday.

They had four in the first five minutes Sunday.

Arizona coach Sean Miller had been concerned about ballhandling after the Wildcats coughed up 17 turnovers against Oral Roberts last Tuesday and the 18 against ETSU.

"It's disappointing when you're this far along and in a tournament like this - and we can't play without turning the ball over," Miller said after the Wildcats beat ETSU. "If we keep doing it, we're not going to win. It's amazing that we're 10-0 with our inability to handle the ball. We're averaging 15 a game and that's a lot for a good team.

"Generally, the teams that I coach average 12, and there's a huge difference between 15 turnovers a game and 12."

Miller also said Saturday that "it's difficult to win" when your point guards have nine turnovers, as Mark Lyons and Jordin Mayes did Saturday. But Lyons had just three turnovers to four assists Sunday and Mayes had one turnover.

Besides, the Wildcats found other ways to win. Tarczewski led the way on the boards for Arizona with 13 rebounds while he also had eight points.

Lyons led UA in scoring with 19 points and four assists, while Nick Johnson had 12 points and Kevin Parrom had 11.

Kenny Kadji led Miami with 19 points.

Arizona expanded a 12-point halftime lead to 53-37 eight minutes into the second half after Kevin Parrom answered Shane Larkin's three-pointer with one of his own.

Arizona hit 51.9 percent of its field goals over the first eight minutes of the second half, and the game was not close after that point.

In the first half, Arizona used rebounding and hot three-point shooting to go on a 20-6 run late in the first half and take a 37-25 halftime lead.

The Wildcats made 6 of 11 three-pointers and had at least one from five different players, while making 51.9 percent of their shots overall. They also out-rebounded Miami 21-8 before halftime.

The shooting helped offset eight UA turnovers in the first half, though Lyons had three assists and no turnovers.

Lyons led the Wildcats in first-half scoring with 10 points, making 2 of 4 threes, while Johnson added eight and Parrom had seven.

Big man Kadji led Miami with 13 points.

The Wildcats started the game ominously with four turnovers and four fouls in the first five minutes, with two fouls by Brandon Ashley, the team's best player on Saturday against East Tennessee State.

But UA still led 5-4 at that point and never trailed by more than two points in the first half.
