SPOKANE, Wash. -- For the first 30 minutes of Thursday night's game, Gonzaga and No. 16 Saint Mary's fought basket-for-basket in a showdown of the West Coast Conference leaders.
Then Gonzaga made three 3-pointers in a 2-minute span and cruised to a 73-59 victory.
"Our guys battled for 30 minutes," Saint Mary's coach Randy Bennett said. "We have to play 40 up here.'
"We played probably a C-plus, B-minus game," Bennett said. "That's not going to get it here."
The Gaels shot just 38 percent and were outrebounded 40-26.
Gonzaga's Kevin Pangos scored 27 points.
"I thought he was exceptional," Bennett said of the freshman guard. "He hit every shot."
Gonzaga was blown out last month in its first game against Saint Mary's, and center Rob Sacre said the Bulldogs did not want that to happen again.
"We played our game, our tempo," said Sacre, who added 12 points and nine rebounds.
"We were hungry to get back at them," Sacre said of the 83-62 loss to the Gaels on Jan. 12.
The win kept alive the hopes of Gonzaga (19-4, 9-2) to win its 12th consecutive regular season title, the second-longest streak in Division 1 history after UCLA's 13 straight.
But the Zags will need somebody to beat Saint Mary's (22-3, 11-1), which saw its 12-game winning streak snapped. Their last loss was Dec. 22 to No. 6 Baylor.
"I told them before the game, `Everybody in the building needs to know who the toughest guys were,'" Gonzaga coach Mark Few said. "Our bigs played tough. Our guards played tough."
Gary Bell Jr. scored 12 points and Elias Harris had 10 points and 10 rebounds for Gonzaga, which shot 52 percent.
Few was impressed with the play of Pangos and Bell, freshmen guards who both played more than 30 minutes.
"They have big wills, big hearts," Few said.
The game was a back-and-forth battle until the final 13 minutes, when Gonzaga outscored the Gaels 28-14.
"I think it's always defense," Pangos said of the late rally. "You start runs by getting stops."
Bennett said the rebound difference was a key.
"They were just more aggressive there," Bennett said. "Eventually that paid off big dividends for them."
Matthew Dellavedova had 20 points for Saint Mary's, which was just 5 of 21 from 3-point range.
"For the first 25 minutes, our defense was like good to OK," Dellavedova said. "But we broke down and they were getting lots of penetration and hitting a lot of open 3s."
Gonzaga was 7 of 15 on 3s.
Trailing by three points at halftime, Saint Mary's opened the second half with a 9-4 run to take a 40-38 lead. But consecutive 3-pointers by Pangos and Bell put Gonzaga ahead 44-40.
The teams traded baskets until Pangos hit a 3-pointer with 8 minutes left to extend Gonzaga's lead to 56-49. Bell added another 3 a minute later and Gonzaga led 59-49.
After two free throws by Dellavedova, Pangos hit his fifth 3-pointer in as many attempts for a 62-51 lead with 6 minutes left.
Gonzaga has won or shared the WCC regular season title every year since 2000-01.
Gonzaga is 101-7 in the McCarthey Athletic Center since it opened in 2004
