Sophomore Steve Moundou-Missi drives to the basket during the Harvard men's basketball team's matchup against St. Mary's. At the half, the Crimson leads, 35-21.

MORAGA, Calif.— Trailing the Harvard men’s basketball team, 69-68, with 1.1 seconds remaining in Monday night’s contest, St. Mary’s forward Mitchell Young found himself at the free throw line shooting one-and-one. And the senior—whose team closed the second half on a 12-1 run—came through in the clutch for the Gaels, knocking down both attempts to give his team its first lead of the contest.

After a Crimson timeout, sophomore Steve Moundou-Missi launched a desperation pass toward the other end of the court but Harvard—which led by as many as 18 points on New Year’s Eve—didn’t connect in the final second, falling to the heavily favored St. Mary’s squad, 70-69, at McKeon Pavilion.

“[I’m] incredibly disappointed,” Harvard coach Tommy Amaker said. “We felt we outplayed them for the majority of the game.”

With 3:56 to play, sophomore Jonah Travis—who ended the contest with a game-high 19 points—dunked the ball to push Harvard’s then-dwindling lead to 10. But from there, it was all St. Mary’s. The Crimson (7-5) added just one more point to its total—a single free throw with 1:30 to play from co-captain Christian Webster—as the Gaels (11-3) closed the gap.

“It was one of those dream stories, and fortunately we were on the positive end of it,” said St. Mary’s coach Randy Bennett.

Young converted a layup and four free throws in the final 3:36 of the game to end the contest with a team-high 16 points. On the other end, Harvard turned the ball over three times and missed two free throws during that final stretch.

“We made too many critical mistakes with handling the basketball, not making foul shots,” Amaker said. “We couldn’t come up with a defensive rebound, a critical one, to see if we could seal this game.”

St. Mary’s earned a total of 16 offensive boards to Harvard’s six over the course of the game, though both teams ended the contest with 21 rebounds on defense.

“I’m really disappointed for our kids because I thought we played incredibly well,” Amaker said. “We gave up too many offensive rebounds and that’s a formula for disaster.”

Despite entering the second game of its West Coast swing as 12-point underdogs, Harvard held a commanding 35-21 lead over St. Mary’s at halftime.

But the Gaels crawled back into the contest, thanks in part to an impressive second-half effort from deep. After shooting just over 11 percent from three-point range in the first half, the Gaels knocked down their first five attempts in the second, pulling within 10 points of the Crimson with 16:40 remaining.

“We got a little too comfortable after halftime,” Travis said. “That gave them the perfect opportunity to hang in there and get the W. That just shows [that] it’s not how you start, it’s how you finish.”

But sharpshooting from the Harvard guards—Chambers and Rivard were a combined 8 for 9 from three-point range on the game—helped the Crimson maintain a lead for all but one second of the second half.

Harvard came out strong at the start of the contest, claiming a 9-3 advantage in less than four minutes of play—headed by a six-point effort from Travis—and did not relinquish the advantage at any point in the opening frame.

“It was amazing,” said Amaker of Travis’ performance Monday night. “I thought he played his butt off. We missed not having him in there with foul trouble and then we fouled out at the end.”

St. Mary’s cut the Crimson lead to two points at 11:56, as Gaels’ forward Brad Waldow knocked down one-of-two free throws to make it 14-12. But an 18-2 Harvard run in the ensuing 8:51 pushed the Crimson to an 18-point lead with 2:35 remaining in the contest.

Moundou-Missi and freshman point guard Siyani Chambers led the way for the Crimson during that stretch, with six points apiece. Moundou-Missi converted an and-one layup and followed up with his first three pointer of the season, while the rookie knocked down back-to-back threes.

With 51.9 seconds to play in the period, St. Mary’s guard and leading scorer Matthew Dellavedova scored his only two points of the half on a pair of free throws, and he finished the game with a season-low four points. Sophomore Wesley Saunders was tasked with defending the guard for a majority of Monday night’s contest.

“That’s a lot to ask of person but he’s definitely stepped up to the challenge,” said Travis of Saunders’ defensive effort. “He’s definitely a big reason why we’ve had the success that we’ve had.”

Though the Gaels struggled from the field in the first frame, shooting just 22.6 percent from the field and one of nine from three-point range, St. Mary’s staged a comeback with an impressive 17 for 26 shooting effort in the second.

“They made all the plays necessary down the stretch to win it, and I think to steal it, to be very honest,” Amaker said.
