Once again Juan Martin del Potro is on course for a blockbuster encounter during the early stages of a tournament.
This time it is at the Miami Open, where the Argentine could play the formidable Roger Federer in the third round. The encounter will only occur if both players triumph in their second round matches. Del Potro will face either Robin Haase or Elias Ymer. Meanwhile, Federer starts his campaign against America’s Francis Tiafoe.
