Tearful Isner signs off with US Open loss

John Isner brought the curtain down on his tennis career Thursday in a five-set loss to fellow American Michael Mmoh in the second round at the US Open.

The 38-year-old Isner surrendered a two-set lead as world number 89 Mmoh saved a match point and came back to win 3-6, 4-6, 7-6 (7/3), 6-4, 7-6 (10/7) in just under four hours.

“It’s tough,” said an emotional Isner, who buried his head in his towel while soaking up the adulation of the Grandstand crowd.

“Just like today, to play in front of this crowd, to have the support I have, is pretty special.
