Jack Sock sweated out a five-set win over Robin Haase. Had rain not pushed the conclusion to a second day, he might already be on a flight out of Paris. As it was, Sock did not exactly endear himself to the French fans when, according to, he screamed out at Haase and then put his fingers on his lips to respond to the fans’ boos.

Sock might regret not having better support over the next match or two, or he might use this as motivation to be more focused. Regardless, he’s going to need to back up his serve and big forehand with better defense and patience.

Last year, Sock proved he could play at Roland Garros when he won his first three matches, including wins over Grigor Dimitrov and Borna Coric. He took a fourth-round set from Rafael Nadal before bowing out.

The road to Week 2 is easier this week. He should be able to overpower charismatic athlete Dustin Brown and then outlast one of the many pesky clay-courters from either Spain or Argentina. As long as he doesn’t self-destruct, Sock will be in. Maybe he will tone down the emotion and show more deference to the French fans. It could help.

Sock is the only ATP player selected for this article. I don’t like John Isner’s chances to play roulette with his serve on clay and against No. 19 seed and Frenchman Benoit Paire in the third round, that is if he gets by Kyle Edmund in the second round.
