The NCAA Division I men’s lacrosse tournament could experience a severe case of poison Ivy.

High-scoring Brown, led by junior attack Dylan Molloy of Setauket and St. Anthony’s, the nation’s leading scorer, earned the No. 5 seed and a home game against Johns Hopkins next weekend. Stingy Yale, the No. 4 seed led by senior defenseman Michael Quinn from Port Washington and Chaminade, will host Navy.

Those two Ivy League schools were among the eight seeded teams announced last night on the sport’s Selection Sunday. The other seeds are Maryland (1), defending champ Denver (2), Notre Dame (3), Marquette (6), Loyola (7) and Syracuse (8). All will host first-round games next weekend.

For Brown, that means the possibility of playing two home games in its quest to reach the Final Four for the first time since 1994 because the Providence school was already designated as a host for this bracket’s quarterfinals.

The Bruins rely heavily on the strong, aggressive Molloy, whose totals of 50 assists and 56 goals are tops in the country. “He comes in with a bulldozer approach,” Brown coach Lars Tiffany said. “He wants to be the best lacrosse player in the country and the weight room is his friend.”

If Brown can make it to the Final Four on Memorial Day weekend (May 28-30) at Lincoln Financial Field in Philadelphia, he can challenge the all-time single-season scoring record of 128 points set by Albany’s Lyle Thompson.

Yale, which defeated Harvard on Sunday in the Ivy League final, is the nation’s sixth-best defensive team with Quinn, a first-team all-Ivy selection, as the anchor.

In the men’s Division II tournament, two Long Island schools were named to the eight-team field and will play Saturday in the North Regional quarterfinals. No. 3 LIU Post (12-3) will play at No. 2 Merrimack (14-2) and No. 4 NYIT (13-4) will visit No. 1 and unbeaten Le Moyne (17-0). Limestone (19-0) is the top seed in the South Region. The Division II championship game will be played May 29 at Lincoln Financial Field in Philadelphia.

In the women’s Division II tournament, defending champion Adelphi (19-0) is the No. 1 seed in the North Region and will have a bye in the first week of the 12-team event. Adelphi will host the winner of next weekend’s game between No. 4 Dowling and No. 5 Grand Valley State, which will be played at Adelphi.
