Miami Open: Del Potro and Djokovic on early collision course

Miami, March 20: Juan Martin del Potro and Novak Djokovic are on course for a blockbuster fourth-round meeting at the Miami Open following Monday's draw.

Seeded fifth in Miami, Del Potro will have his work cut out if he is to secure successive victories, facing either Yuichi Sugita or Robin Haase in the second round before a possible last-32 meeting with 2016 runner-up Kei Nishikori.

Six-time champion Djokovic, who holds a 14-4 head-to-head advantage over Del Potro, is looking to surpass Andre Agassi's record by winning a seventh crown, although the Serbian comes into the tournament having suffered a surprise early exit to Taro Daniel at Indian Wells.

Federer and Marin Cilic are the top two seeds, the three-time winner getting his campaign under way against a qualifier while the Croatian will face either Pierre-Hugues Herbert or Taylor Fritz.
