Sloane Stephens had her best season ever working under USTA Player Development coach David Nainkin, finishing the year at No. 12 and reaching the second week of every Grand Slam event.
Sloane Stephens just upset 5-time Australian Open winner Serena Williams in a 3-set battle in the quarterfinals down under.
Stephens is a major talent, but she has had a hard time keeping healthy and revealed in Brisbane that at the 2012 US Open she tore an abdominal muscle, so badly so that it bled.
