The streak is now seven and counting.The Columbia men's swimming team defeated host Bucknell 167-133 at Arthur Kinney, Jr. Natatorium to notch its sixth win of the season and its seventh consecutive dual meet victory since last season. The Lions (6-0, 4-0 Ivy) won 12 of 16 events, taking four of the five freestyle events and sweeping the butterfly, backstroke, and diving events. Junior Tobin White, sophomore Henning Fog, and freshman Hyun Lee each had outstanding performances on Saturday, winning two events apiece.The Bison (2-7) drew first blood with a narrow win in the 200-yard medley relay. But, the Light Blue relay teams wrapped up second and third in that event less than a second behind the Bucknell squad. "The loss was kind of surprising for us," freshman Kevin Wakefield said, noting that the medley relay was traditionally a strong event for the Lions.Columbia roared back in the next event, the 1650 freestyle, as the trio of Fog, junior Jake Abbott, and senior Dave Bazylewicz placed first, second, and third, respectively.Fog's winning time of 16:03.25 was 42 seconds faster than his nearest Bucknell opponent. The Lions took four of the top five places in the next race, the 200-yard freestyle, with Wakefield crossing the finish line 0.63 seconds ahead of Bucknell's Todd Bauer. In the 100-yard backstroke, White raced to a 52.74 first-place finish, barely a quarter of a second ahead of Bison swimmer Mark Kretzer. However, Columbia lost the next battle of the times, as Bucknell's Brad Bennett won the 100-yard breaststroke in 59.16, 0.15 seconds over first-year Zach Glassman. The Lions answered with a win in the 200-yard butterfly by Hyun Lee, only to finish third in the 50-yard freestyle.Sophomore Justin Reardon swept the diving events for the Lions, winning the 1-meter and finishing 50 points ahead of his nearest opponent in the 3-meter.Lee sustained the Lions' momentum in the swimming events, winning the 100-yard freestyle in 46.34 seconds, and White swept the backstroke events with a win in the 200-yard back of 1:55. Glassman avenged his second-place finish in the 100-yard breaststroke with a win in the 200-yard breaststroke. Fog picked up his second win of the day, racing to first place in the 500-yard freestyle with a time of 4:43.Senior Ben Neuwirth completed Columbia's sweep of the butterfly events with a win in the 100-yard fly, and freshman John Dragelin closed out the individual events with a first-place finish in the 200-yard individual medley.The Lions face a short week and a busy weekend, traveling to Rutgers on Friday and returning to league play on Saturday against Cornell at Uris Pool."We lost to both these teams last year," Wakefield said. "It would be great if we could keep the undefeated streak going."
