Sophomore Sam Wollner won two races as the Harvard men's swimming and diving team took first place in the final seven events of the day for a season-opening sweep of Cornell and Dartmouth in a home meet Saturday at Simmons College.

The Crimson (2-0, 2-0 EISL) trailed Cornell (1-1, 1-1 EISL) for much of the afternoon, but its run of seven straight wins turned a 26-point deficit into a 25-point win. Harvard led throughout against the Big Green (0-2, 0-2 EISL) and extended its winning streak to 12 straight dual meets. Cornell defeated Dartmouth, 238-62.

Wollner's first win came in the 200-yard butterfly, as he finished in 1:53.76, followed by freshman Bill Jones. Wollner later took the 500 freestyle in 4:32.96, leading three Crimson swimmers in the top four and pulling Harvard to within a point of Cornell at 113.5-112.5.

Jones then won the next race, the 100 butterfly, in 50.34 to give Harvard its first lead over the Big Red, 124.5-120.5. He was one of two freshmen to register an individual victory in his first collegiate meet. Eric Lynch emerged victorious in his first collegiate race, winning the 1,000 free in 9:29.81.

Senior captain David Cromwell started the run of Crimson wins with his triumph in the 200 back, where he finished in 1:48.42. The other team captain, Bill Cocks followed that performance by taking the 200 breaststroke in 2:08.81, setting up Wollner and Jones to give Harvard the lead for good against Cornell.

Senior Danil Rybalko, sophomore Geoff Rathgeber and a Crimson 200 free relay team finished up the meet with wins. Rybalko won the three-meter diving with 304.6 points, Rathgeber finished in 1:51.72 to take the 200 individual medley, and Harvard took the relay in 1:23.94. Seniors Mark Knepley and Cromwell, freshman David Guernsey and sophomore Pat Quinn made up the winning relay squad.
