Maryland erupted for eight goals in the fourth period to score a 16-13 comeback victory over Syracuse yesterday in an NCAA lacrosse quarterfinal at Byrd Stadium.

The Terrapain triumph earned the hosts a 2 p.m. Saturday semifinal data against Navy, which beat Massachusetts, 16-14. Maryland has advanced to the semifinal round of every NCAA tournament in the nine-year history of the national playoffs.

But Syracuse, seeded seventh in the eight-team field, gave Maryland all it could handle for three periods. The Orangemen, who finished 10-5, outhustled the Terps and took the No. 2 seeds out of their offense until the final quarter.

Then Maryland, now 8-1, flexed its offensive muscle behind the shotting of Ron Martinello and Bob Boneillo and the playmaking of John Lamon.

Syracuse led, 10-7, late in the third period but hurt its cause with three penalties. The extra-man situation allowed the Terps to score three consecutive goals and tie the score at 10-10 with 12:57 left in the game.

Martinello gave the Terps at 11-10 lead when he knocked in a rebound off Syracuse goalie Jamie Malloy. Ralph Spinola tied the score 1:03 later with his second goal for Syracuse.

Maryland got a one-hop goal from Lamon and an unassisted score from Nick Manis 46 seconds apart for some breathing room.

The closest Syracuse came after that was when Tim O'Hara took an assist from Kevin Donahue (five goals, three assists) to make it 14-13 with 5:31 left.

Thirty-five seconds later, Bonello scored unassisted.
