Kerber ousted in New Haven

Second-seeded Angelique Kerber went by way of the upset Tuesday at the New Haven Open, a final U.S. Open tune-up.

Former runner-up Elena Vesnina of Russia upended the left-handed German Kerber in 6-2, 6-4 fashion in second-round action on the hardcourts at the Connecticut Tennis Center at Yale University. Vesnina reached the final here back in 2009.

Also in the second round, Czech veteran Klara Zakopalova topped promising Puerto Rican Monica Puig 6-4, 6-1 to reach the quarters, where she'll meet Vesnina.

The 2013 New Haven titlist will earn $117,000.
