HANOVER, N.H. - The day after dropping an Ivy League match in the windy conditions at Harvard, the Columbia men's tennis team rebounded to top Dartmouth, 4-1.

The win gave the No. 20 team in the nation a 15-4 overall record, while the Lions move to 4-1 in Ivy League play. With Harvard dropping a 4-1 contest at No. 25 Cornell today, the Lions, Crimson and Big Red are all tied for the lead in the conference.

Columbia came out ahead in the doubles round, stealing the point with wins in the first and third matches. After losing their doubles match the day before, Michal Rolski and Christopher Grant were winners against Ciro Riccardi and Roko Glasnovic, 6-4.

With Victor Pham and Richard Pham dropping the second match, it came down to the No. 89 pair of Shawn Hadavi and Jackie Tang to clinch. The senior and the rookie did just that, giving the Lions a 1-0 edge with a 7-5 victory.

Only two of the singles matches went down in straight sets, as the Big Green and the Lions had to fight the rest of the match out.

Hadavi was one of those two-set winners, taking the top match against Charlie Broom, 6-1, 7-5. The No. 96 player in the country improved to 4-0 in Ivy League contests, with one unfinished match this spring.

The other quick match went to Dartmouth's George Wall, who knocked off Alex Keyser in the No. 4 match, 7-6, 6-2.

Jackie Tang picked up a three-set victory against Max Fleigner in the third match, coming out on top, 6-2, 2-6, 6-1. The fifth match went to Adam Ambrozy who came through with a 6-4, 5-7, 6-3 win, helping the Lions to the team triumph.

Columbia retuns to the Dick Savitt Tennis Center next weekend, with the final two Ivy League duals on deck. The Lions battle Brown (11-9, 0-5) on Saturday at 1 p.m., before hosting Yale (16-7, 2-3) on Sunday at the same time. With a pair of wins, Columbia could guarantee at least a share of the Ivy League title for the fourth consecutive season.
