Senior Denny McCarthy, a three-time All-Met and The Post’s Player of the Year last season, shot a 3-under par 69 to win his third consecutive individual title and lead Georgetown Prep to its fifth consecutive Interstate Athletic Conference team championship on Tuesday at Shenandoah Valley Golf Club in Front Royal, Va.

Bailey Patrick of Episcopal finished second after shooting 71, the only other player to break par.

McCarthy said that windy conditions made it difficult to score better, but that he could have shot a few strokes lower. Still, birdies on the final two holes allowed him to pull away.

Of more concern, McCarthy said, was the team championship. The Little Hoyas finished with a team score of 393, just two strokes better than second-place Landon, which was led by the tournament’s third- and fourth-place finishers, Ralph Blasey (73) and Robert Balaban (75).

“I wasn’t really worried about” the individual title, McCarthy said. “I was worried more about how we would do team-wise.”

Sam Spikell and Nate Cohan helped Georgetown Prep by tying for sixth place at 78.

Georgetown Prep and Landon advanced to the Washington Private Schools Championship on May 17 against the top two teams from the Washington Catholic Athletic Conference.

Gonzaga edges DeMatha

Sophomores Luke Malanchuk and Addison Coll and senior Max Ruge posted individual victories as Gonzaga edged DeMatha, 5-4, in a Washington Catholic Athletic Conference meeting of undefeated teams on Tuesday at the Country Club of Woodmore in Upper Marlboro.

DeMatha All-Met senior Ben Warnquist beat Gonzaga’s Keegan Boone, 1-up, at No. 1, but Errol Clarke was the Stags’ only other individual winner.

“Every match pretty much went to the last hole in some way, shape or form,” DeMatha Coach Dan Spotts said.

Gonzaga plays Georgetown Prep on Monday.
