HONOLULU -- Hawaii's Zane Johnson might have located his missing long-range shooting stroke.

Johnson hit six 3-pointers and finished with 27 points as Hawaii beat Clemson, 75-68, on Sunday in the fifth-place game of the Diamond Head Classic.

"Hopefully it can stay like this, and I don't have to go through a slump again," said Johnson, who entered the game 28 of 87 from 3-point range. "Coach Gib (Arnold) always tells us that shooters shoot and to shoot yourself out of a slump. I think I did, and hopefully I can keep playing the way I did today."

Johnson finished 8 of 14 from the field, with four of his 3-pointers coming over the first 13 minutes of the second half.

"When a guy like Zane Johnson is hitting those 3s, all of a sudden I'm a really good coach, everything starts to work," Arnold said. "He was defended on a bunch of them, but we kept running stuff at him."

Vander Joaquim added 14 points and 10 rebounds for Hawaii (7-5).

Andre Young scored 14 points to lead Clemson (7-6).

Most of Johnson's 12 attempts from 3-point range were from the wings as he came off screens.

"They were really setting great screens tonight," Johnson said. "They were down and low, had a wide base, so it was hard for the defender to trail me right off the bat, because they're going to get bumped. And if they do try to shoot the gap, our bigs were recognizing it and sliding just a little bit over and changing positions so I could flare off of it."

The Rainbow Warriors, who trailed 34-28 with 1:45 left in the first half, went on a 9-0 run to start the second half for a 40-34 lead.

Johnson scored eight points, including two 3-pointers, during a 10-3 spurt that put Hawaii up 59-48 with 5:43 remaining.

"Johnson is a really good player, and we didn't do what we were supposed to do in the game guarding him," said Clemson coach Brad Brownell. "We let him get going, and when he plays like that, they're hard to beat."

Hauns Brereton added 10 points and Jeremiah Ostrowski had eight assists for Hawaii, which made 15 of 25 shots in the second half.

"We started moving it around, and that's when we made our big run," Arnold said.

Clemson used full-court pressure late to make it interesting. The Tigers scored six in a row to get within 69-64 with 35 seconds left.

"Nobody wanted to give up," said Clemson guard Rod Hall. "We just wanted to fight till the last minute."

In its two previous tournament games, Hawaii lost to Auburn, 65-62, and beat No. 14 Xavier in overtime, 84-82.

"I always knew that we had some pieces to the puzzle -- we had to twist some and bend some -- but for us to be close against an SEC team, to beat an ACC team that went to the NCAAs last year with most of their starters back and a Top 20 team in Xavier, it was a good week for us," said Arnold.

Clemson played without forward Milton Jennings, who was serving a one-game suspension for arguing with Brownell during the Tigers' 83-75 overtime victory Friday over Southern Illinois.

"We're disappointed with his actions during a timeout against Southern Illinois on Friday," Brownell said of the former Pinewood Prep sandout. "I was proud of how he came out after he cooled off, cheered on his teammates and apologized to the team after the game. But, we certainly don't condone that type of behavior."

Hawaii held a 37-29 rebounding advantage. Joston Thomas and Trevor Wiseman each grabbed six for the Rainbow Warriors.

Devin Booker added 13 points and seven rebounds, and Tanner Smith had 12 points for Clemson, which was 12 of 33 from the field in the second half.
