Clearly buoyed by the fans behind him, the 20-year-old certain put the Serbian to work with his huge serve causing all sorts of problems.
Shelton, who played American Football as a quarter-back in high school, has already recorded the fastest first serve of the US Open so far this year, reaching 149mph against Tommy Paul.
However he’s now broken another record, with his 143mph effort being the fastest second serve of the tournament as well.
