CAMBRIDGE, Mass. -- Brown upset No. 21 Harvard 4-2 on Thursday evening, handing the Crimson their first Ivy League loss of the season. The Bears (14-9, 3-3 Ivy) won an extremely tight doubles point and then earned three singles wins to pick up the victory.

Brown's No. 1 doubles team of Daniel Hirschberg and Michael Riechmann opened the match with a 9-8 win against Denis Nguyen and Casey MacMaster, the 71st-ranked team in the country, but the Bears' No. 2 team of Brandon Burke and Sam Fife fell by the same score to Nicky Hu and Andy Nguyen. Brown's third team of Lucas Da Silveira and Justin To rallied from a 6-3 deficit to win 9-7 against Alex Steinroeder and Kelvin Lam, securing the doubles point for the Bears.

Steinroeder quickly righted the ship for Harvard, leveling the match score at 1 with an impressive 6-1, 6-2 victory against Hirschberg on the fourth court. Hu was next up for Harvard, polishing off Burke in straight sets, 6-4, 7-5, to give Harvard a brief 2-1 lead. Brown came back with another match point at No. 6 where Da Silveira took down Lam 6-3, 6-4.

Fife claimed a three-set win, beating Andy Nguyen 7-5, 5-7, 6-2 at No. 3 singles to give the Bears a 3-2 lead, before Riechmann earned a three-set win, 1-6, 7-6, 6-3 against Denis Nguyen, at No. 1 singles to clinch the victory for Brown.

Harvard (17-5, 5-1 Ivy) still can claim the outright league title Saturday at Dartmouth.
