Brian Costabile (Mount Saint Joseph) gave No. 4 Notre Dame the lead for good with 2:06 left in the third quarter and the host Fighting Irish held on to upset No. 1 Maryland, 5-4, in men’s lacrosse Saturday.

The Terps fell to 4-1, and Notre Dame improved to 3-0.

Costabile’s goal gave the Irish a 4-3 lead before Brendan Gleason added his second goal for a 5-3 lead with 12:33 left in the game. Connor Kelly scored with 18 seconds left to bring Maryland within one.

Tough defense resulted in a scoreless first quarter. Only nine shots were taken, six by Notre Dame and three by the Terps.

Dylan Maltz gave Maryland a 1-0 lead with 10:03 left in the second quarter before the Irish responded with goals by Gleason and Mikey Wynne (St. Paul’s) for a 2-1 halftime lead.

No. 11 Loyola Maryland 16, Holy Cross 9: Pat Spencer (Boys’ Latin) broke the Patriot League single-game record with nine assists for the host Greyhounds (3-2, 2-0).

The Crusaders fell to 1-4, 1-1. All 16 of Loyola’s goals were assisted.

Spencer’s nine assists are the school record for a game, matching the output of Gary Hanley in an April 25, 1979, game against Morgan State. The nine assists are a Loyola Division I record, eclipsing the seven Brian Duffy had April 1, 1995, against Towson State.

The total marks the most in NCAA Division I this season and are tied for 10th most ever in an NCAA Division I game. The sophomore also tied his career-high with 10 points in the game.

The previous Patriot League record of eight was held by three players: Tim Pearson (Army, 2002), Chris Cara (Bucknell, 2004) and Jon Brisner (Navy, 2005).

Stevenson 11, Gettysburg 6: Wade Korvin (Arundel) had a hat trick to lead the visiting Mustangs (1-1) past the Bullets (2-2).

Stevenson won 15 of 21 faceoffs and outscored Gettysburg 8-4 in the second half.

No. 1 Maryland 18, Hofstra 7:

Senior midfielder Zoe Stukenberg (Marriotts Ridge) tied her career high with five goals as the Terps (4-0) beat the host Pride (2-2).

“It was really cold and windy, but I think the team found a way to get things going and be effective across the field,” Maryland coach Cathy Reese said.

“Our offense really started rolling in the first half, and Megan Taylor (Glenelg) had another great performance to lead the defense.”

Stukenberg scored on all five of her shots. Junior attackers Megan Whittle (McDonogh) and Taylor Hensh (Marriotts Ridge) each had a hat trick.

Senior attacker Caroline Wannen and sophomore midfielder Jen Giles (Mount Hebron) scored twice.

Taylor made 10 saves while allowing six goals for a .625 save percentage.

Neither team found an offensive rhythm early on, but O’Donnell eventually led Penn State to a 4-2 advantage. After almost nine scoreless minutes, the Nittany Lions scored three-straight goals in a little over two minutes to pull ahead 3-0 at the 19:05 mark.
