USTA Strength and Conditioning Coach Reshard Langford joins the team to discuss "the bubble" in New York and how players are dealing with it. We also review the first day and a half of US Open action and some of more interesting things going on so far. How are the players doing after not playing Grand Slam tennis since January? There have been many long matches and momentum shifts and we discuss some reasons why. Instagram: @teamusatennis / @johnny_parkes Twitter: @larrylauer / @johnnyparkes1
