This week’s ATP tennis action is well underway in Miami and all the first round matches involving unseeded players and qualifiers are now settled. The second round action commences this afternoon and the top-30 seeds enter the fray today and tomorrow. Brit Kyle Edmunds faces a baptism of fire against world number one and defending champion Novak Djokovic while second seed Andy Murray gets his campaign up and running against Dennis Istomin.

The returning Roger Federer faces a potential banana skin against former top-10 star Juan Martin Del Potro, who is still attempting to rebuild his career after a troublesome wrist injury kept him off the tour for long periods. Both of our outright selections for this week, David Goffin to win the second quarter (14/1) and Rafael Nadal to win the tournament (18/1), also kick off their campaigns and both should progress without too much drama.

From a match perspective Del Potro at just short of 5/2 has to be given a decent outsiders chance against Federer, who is returning from knee surgery and playing his first competitive match since the Australian Open. Qualifier Taylor Fritz also has to be respected at 2/1 against eighth seed veteran David Ferrer, who has not played since Acapulco last month.
