The No. 25 Harvard men's tennis team (6-0) overcame experimental rules and a pesky Kansas team to win 6-2 on Friday at the Murr Center.

Senior John Doran held off Rodrigo Echagaray in a tiebreaker at No. 1 singles after splitting sets. His cousin, senior Joe Green, won 6-4, 6-3 at No. 3 singles.

Also victorious in singles were sophomore William Lee at No. 4 and junior Mike Rich at No. 6. Lee won 10-6 in a tiebreaker that served as a deciding set against Pete Stroer, and Rich won 7-6, 6-4 over Sebastian Libertino.

Harvard swept the doubles matches, earning two points under the experimental rules.

Green and freshman Dave Lingman took an 8-6 win at No. 1 doubles. Doran and sophomore Cillie Swart won 8-5 at No. 2, and junior Anthony Barker and Rich won 8-6 at No. 3.

The new rules changes, which are not permanent, stipulated that the doubles matches be played immediately after the player introductions and before the teams have a chance to warm up against each other on the court. A team that sweeps the three doubles matches earns two points instead of one.

Just five minutes after the last doubles match, singles play begins, again without a warm-up. In addition, if the singles players split the first two sets, they play a 10-point tiebreaker to determine the winner.

The new system could end the team match in a tie, in which case the doubles teams would take to the court again for 10-point tiebreakers.
