Right now, only one tennis player on the ATP World Tour has a singles and doubles ranking in the Top 20, and that’s Jack Sock.
It’s a well-earned mark of distinction: Since last year’s Summer Olympics—where he won the bronze medal with Steve Johnson in men’s doubles and the gold in mixed with Bethanie Mattek-Sands—until now, Sock has played in seven finals between singles and doubles, and led the U.S. to a runner-up finish at the Hopman Cup to start the season.
He’s established himself as a dual threat, but how much tennis is too much? And could all of that time on the court leave him in a less-than-ideal state for the year’s remaining Grand Slams?
Before this past weekend’s Davis Cup tie against Australia, Sock made the doubles final at the Miami Open with partner Nicholas Monroe. This came after reaching the singles quarterfinals there, where he lost to Rafael Nadal.
