BALTIMORE — Perhaps it wasn’t a perfect afternoon for Louis Perfetto and the Boston University men’s lacrosse team.

Still, it was close enough.

Perfetto set career highs in assists (six) and points (eight) as the Terriers shook off a pair of nonconference losses, upending Loyola 14-9 to remain undefeated in Patriot League play.

Vince D’Alto and Timmy Ley both scored three times for the Terriers (9-3, 6-0 Patriot), who won at the Ridley Athletic Complex for the first time in five tries against Loyola. Boston University was 0-7 in the facility all-time including neutral-site Patriot League tournament games.

“The tendency in this program’s history is that when we get late in the year, we kind of falter,” said coach Ryan Polley, whose team fell to both Yale and Princeton last week. “To be able to play our best lacrosse and our best game of the year against a quality opponent was a great thing.”

Kevin Lindley had three goals, Aidan Olmstead had three assists and fifth-year defensive midfielder Matthew Benus had his first three career points (one goal, two assists) for the Greyhounds (5-6, 4-2).

The Terriers are adapting to injuries at both ends of the field, and their ability to do so against Loyola was encouraging. Junior defenseman Patrick Morrison missed his third consecutive game, leaving Boston University without its quarterback at that end of the field.

While Morrison is expected back later in the season, senior midfielder Jake Cates is not. Saturday was the Terriers’ first since Cates (21 goals, eight assists) was lost for the year, but it also illustrated just how much offensive depth Polley’s team enjoys.

Boston University made its push in the third quarter after Loyola took a brief 6-5 lead. Ley tied it with his 100th career goal after a behind-the-back feed from D’Alto, and from there Perfetto made things miserable for the Greyhounds.

It was his skip pass to Matt Baugher that gave the Terriers the lead for good with 6:30 left in the third quarter. Within the next two minutes, he had a goal and another assist, and Boston eventually pushed its advantage to 13-7 on a Ley-from-Perfetto goal early in the fourth quarter.

“I know we rode really hard, causing a lot of turnovers and getting a lot of ground balls back,” Perfetto said. “Every time we get the ball back, it’s a new shot clock and more time to wear them down. The big/little from behind was fantastic for us, and my teammates did a fantastic job.”

The Terriers’ 7-1 run chased Loyola goalie Sam Shafer, who made five of his 11 saves in the first quarter. Coach Charley Toomey didn’t think Shafer played poorly, but there were certainly other issues for the Greyhounds to address prior to their final three regular-season games.

Loyola committed 17 turnovers, including 12 after the break as part of its second-half unraveling.

“If we continue to give up four- and five-goal runs, it’s going to be a short season,” Toomey said. “We have to learn how to dig in and get the next tough ground ball. Because I think in that run, the ball hit the ground a few times and they outbattled us to pick it up and throw it over the top of our defense for a shot.”
