Aus Open WC in the bag for Sock
Jack Sock has the USTA's Australian Open wild card in the bag. To surpass the 180 points Sock earned in Paris, another American would have had to win one of the Challengers the last two weeks – plus this week's point-rich event in Houston. There's no chance now. Charlottesville champion Tommy Paul and Knoxville winner Reilly Opelka both are playing Champaign this week. Even if one of them wins it, they can't earn enough ranking points to pass Sock. Sock is close enough to the Melbourne main draw, at No. 106, that playing for second is worth the effort.
