We've got a major upset watch at Arthur Ashe.
Rafael Nadal and wildcard Alun Jones have won a set each after Nadal only squeaked by to take the first, 7-5.
They've both broken in the third set. Nadal is really struggling and there's some mysterious tape below both his knees. Watch for updates here.
UPDATE: Never mind. Nadal won in four sets, blowing out Jones 6-1 in the 4th. Nonetheless, it looked rough for Rafa and he’ll no doubt have something to say about it to the press in a bit.
