Darien won all five singles matches, with three of the matches decided in three sets.

At first singles, Bobby Nuener avenged a straight-set loss to Wilton’s Nick Condos in the regular-season match by rallying for a three-set win, 3-6, 6-1, 6-4.

Russell Mahoney, at fifth singles, had lost to Jay Cassone last time out, but on Thursday rallied from a set down to win in three sets, 4-6, 6-2, 6-1.

At fourth singles, Darien’s Luke Uhlman also went to three sets against Alex Hattenbach, prevailing by the score of 6-3, 4-6, 6-2.

Tim Derby at second singles and Michael Karr at third singles both won in straight sets.

The Warriors swept the two doubles matches, with Jordan Lord and Henry Murphy continuing their impressive season at first doubles with a straight-set victory.
