HARTFORD, Conn. (AP) Villanova Wildcats got off to a slow start in defense of its NCAA championship against a determined, defensive-minded Saint Mary's Gaels team that came in confident after a season-defining win.

But the Wildcats, a No. 6 seed in this NCAA Tournament after an up-and-down season, have one thing no team in the field of 64 has: a pair of leaders who have won two national titles.

Phil Booth scored 20 points, fellow senior Eric Paschell added 14 and Villanova held off 11th-seeded Saint Mary's 61-57 on Thursday night.

''We're growing, our young guys are growing, but we have two seniors who do everything for us, on and off the court,'' coach Jay Wright said. ''We're just so lucky to have them.''

Sophomore Jermaine Sameuls added 12 points for the Wildcats (26-9), who led for almost 33 minutes, but never by more than eight points.

''The tempo was excruciating,'' Wright said. ''We felt going in we were going to have to grind with them.''

The Gaels used the same slow pace to upset Gonzaga in the West Coast Conference Tournament, and it gave them a chance against Villanova (26-9) in a tense opening-round matchup.

Jordan Ford and Malik Fitts each had 13 points for Saint Mary's (22-12). Ford's basket in the lane after a few nifty moves got the Gaels within six points at 61-55 with 34 seconds left.

After Paschell missed a foul shot on the other end, Fitts cut the deficit to four points with a leaner in the lane. The Gaels had two more chances in the final seconds, but Fitts hit the rim on a 3-point attempt and Villanova freshman Saddiq Bey stole the ball from Ford in the final seconds to seal the win.

''We had a few games this year where we put the press on and were able to get back in the game,'' said Ford. ''And if we get a few of those loose balls, or maybe make a three when we were down four, I think it's a different game.''

Saint Mary's led 30-28 at the half, but Booth scored the first five points after intermission during a 12-3 run that put the Wildcats up 40-33. He had 12 points and five of his six assists in the second half.

''We weren't doing that bad, actually,'' Booth said. ''It was more that they were playing very well and we were trying to match how they were bringing it. I think we just had to take it to another level, because they were playing at a high level.''

BIG PICTURE

Villanova: The defending champions are in the tournament for the 14th time in 15 seasons and improved to 14-1 since 2016.

Saint Mary's: The Gaels are 4-6 in opening-round games in the NCAA Tournament and 5-10 overall. Saint Mary's has advanced to the Sweet 16 once in the modern era when it beat the Wildcats in 2010. There's a reminder of that run in the hallway outside the locker room that the players see as they walk out to practice each day in McKeon Pavilion.

EMPTY ARENA

The game tipped to a relatively empty arena, but it wasn't because nobody had bought tickets.

Fans of the Wildcats, many of whom made the 4-hour drive from Philadelphia to Hartford, Connecticut, were lined up along with Gaels fans behind metal detectors as security emptied the arena from the afternoon session.

''You worry about those things, you know?'' Wright said. ''We have a lot of guys in the NCAA Tournament for the first time thinking, `This is the NCAA Tournament?' There's no one in the stands.''

By halftime, the 16,000-seat XL Center was nearing capacity, but some frustrated fans were sill filing in.

FROM DISTANCE

The game was billed as a battle between one of the nation's top 3-point shooting teams in Villanova against some of the nation's best perimeter defenders. In the end, the Wildcats finished 8 of 20 from behind the arc, while Saint Mary's was 8 of 22.

ON THE BOARDS

The taller Gaels won the rebounding battle 33-29 and 10-5 on the offensive end. The Wildcats didn't have an offensive board until the second half and that led to an 11-4 advantage for Saint Mary's in second-chance points. Wright said this year's team was hurt by the transfer of 6-foot-9 Dylan Painter, but is going to have to find a way against taller opponents.

UP NEXT

Villanova will play either No. 3 seed Purdue or 14th-seeded Old Dominion in the second round Saturday.
