It’s now Day 5 of the 2015 Miami Open Masters, and Rafael Nadal is looking to break Novak Djokovic winning streak at this open and take his first trophy from here. He’ll be going up against fellow Spaniard Fernando Verdasco, and all eyes will be watching to see if he can get back on track this year. Yes, I know he’s at number 3, but it’s been a struggle over the past couple years with injuries, and we know that tennis is very much a mental game that can take you out before you even know it. It’s had it’s ups and downs for Nadal, but he’s pulled through before, and he’s that one you just push for. He reminds me of the days when Andre Agassi was on a winning streak and then suddenly losing matches surprising everyone but then rebounding again.
Four of the world’s Top 10 players feature on Day 5 of the Miami Open: No. 3 Rafael Nadal, No. 4 Andy Murray, No. 8 Stan Wawrinka and No. 9 Tomas Berdych. Nadal continues his push for a maiden title against compatriot Fernando Verdasco; two-time champion Murray takes on Santiago Giraldo; Wawrinka clashes with the in-form Adrian Mannarino; and Berdych faces off against a resurgent Bernard Tomic.
NADAL CHASING A FIRST: Nadal is visiting Miami for the 11th time, but is still chasing his first title here. He is a four-time runner-up: 2005 (l. to Federer), 2008 (l. to Davydenko), 2011 and 2014 (l. to Djokovic in both). This is the only tournament he has not won with this many attempts.
CLOSING IN ON 500: Murray is closing in on a significant landmark. The Scot needs just two more victories to join the ‘500 Wins Club’ (498-155). He would become the ninth active player and the 46th man in the Open Era to achieve the feat. Murray surpassed Tim Henman’s haul of 496 career match wins with his QF victory over Feliciano Lopez in Indian Wells last week, taking sole ownership of Britain’s Open Era match-win record.
CARRYING THE FLAG: Jack Sock is one of two American men in the 3R (also John Isner) and the only one on today’s order of play. The world No. 45 returned to competitive action at Indian Wells for the first time since undergoing hip surgery in mid-December. In the Californian desert, Sock reached the 4R at an ATP Masters 1000 event for the first time and he will be looking to replicate the feat when he takes on Dominic Thiem today.
RANKING RISERS: Viktor Troicki, Bernard Tomic and Juan Monaco are all into the 3R, with the latter two in action today. They are among the biggest ranking risers in the Top 50 this year. Tomic’s jump of 27 spots in the Emirates ATP Rankings puts him at World No. 29, while Monaco’s leap of 16 spots places him at World No. 46.
