PHILADELPHIA -- Robert Rotanz led a potent Duke attack with a career-high five goals as the Duke Blue Devils beat the Colgate Raiders 17-6 in the quarterfinals of the NCAA men's lacrosse tournament on Sunday.
Early on, it looked like the upstart Raiders would give the Blue Devils all they could handle. Colgate (14-4) took a 4-2 lead on freshman Ryan Walsh's goal with 3:58 remaining in the first quarter, but it was all Duke after that.
Rotanz scored four goals during the crucial 13-0 Duke run, which spanned 26:14 of the second and third quarters, turning that deficit into a 15-4 lead. The senior midfielder, who entered the game third on the team in points (40), added one more tally with 2:19 remaining in the third quarter to join sophomore Jordan Wolf as the only Blue Devils with five-goal games this season.
Wolf had two goals of his own, joining Rotanz, Christian Walsh (three goals), David Lawson (two) and Jake Tripucka (two) as the Blue Devils with multi-goal games.
The Raiders never threatened after that demoralizing run, getting just two goals in the entire second half as the Blue Devils ran out the clock. Both of those goals were scored by Ryan Walsh, giving him a hat trick as the only Colgate player with multiple goals.
Duke (15-4) has now won 12 of its last 13 games after getting off to a fairly shaky start to begin the season, losing only once since March 10 (April 27 vs. Denver).
The Blue Devils dominated time of possession, getting opportunity after opportunity against an overmatched Raiders defense.
When Colgate would break through for opportunities, it often found itself turned away by Duke goalkeeper Dan Wigrizer, who made a number of impressive saves to maintain his team's comfortable lead.
Duke, which advances to the national semifinal for the sixth straight season, faces Maryland next Saturday with a chance to earn its second national title game appearance in three years. That last time, the Blue Devils beat Notre Dame 6-5 in overtime to clinch the school's first national championship.
