SOUTH BEND, Ind. —Colin Igoe scored three goals and Notre Dame recovered after a slow start to beat Penn 13-6 on Saturday in the first round of the lacrosse tournament.

Nicholas Beattie, Westy Hopkins, Zach Brenneman and Pat Cotter each scored twice for the Irish, who won their first 10 games this season before losing their previous two.

Notre Dame scored four times in the first nine minutes before the Quakers  rallied to within 8-5 at halftime. Notre Dame shut down Penn for more than 27 minutes to put the game away.

Notre Dame -- which spent a few weeks toward the end of the season ranked No. 1 nationally -- advances to next weekend's quarterfinal round. The Quakers, meanwhile, finish the 2011 season 8-7 and will look to build on their best Ivy League finish since 1989 and their first NCAA appearance since 2006.

Notre Dame outshot Penn 41-24 and won 17 of the game's 23 faceoffs to keep possession most of the day. Only a standout performance by the Quakers' freshman goalie, Brian Feeney, kept this game from getting completely out of hand. He had eight saves alone in the second quarter, and finished the game with 14.
