Wimbledon 2017 Betting Odds: Roger Federer, Rafael Nadal Still In Pursuit Of Andy Murray, Novak Djokovic

Oddsmakers continue to favor the four most notable names in men's tennis as the most likely to capture the 2017 Wimbledon title. But entering the fourth round, No. 3-seeded Roger Federer and No. 4 Rafael Nadal, two players that have looked dominant in 2017, trail No. 1 Andy Murray and No. 2 Novak Djokovic as the favorites to win the Grand Slam.

Before the start of the tournament, Federer was the top favorite at +200, according to betting side Bovada.lv. But the Swiss star, who skipped the French Open, has since moved to third at +500.

Murray and Djokovic saw their odds improve. Murray, the defending champion, is the frontrunner at +250, after beginning the tournament at +350. Djokovic has seen the biggest surge, improving from +600 to +300.

On Friday, Murray needed four sets to hold off No. 28 Fabio Fognini of Italy, 6-2 4-6 6-1 7-5. It was the 10th-straight year that the Scot has advanced to the Round of 16.

Djokovic had little problems in his second-round match against Adam Pavlasek of the Czech Republic, 6-2 6-2 6-1. Djokovic, who last won Wimbledon in 2015, will face Latvian Ernests Gulbis on Saturday.

Both Murray and Djokovic have been dominant at the All-England Club. Murray won Wimbledon in 2013 and 2016, while Djokovic won the tournament in 2011, 2014 and 2015.

Nadal dropped from third (+400) to fourth (+600). The Spaniard, who has been in top form in 2017, cruised to a victory Friday over Russian Karen Khachanov 6-1 6-4 7-6(3) in two hours and 15 minutes. He will face Gilles Muller of Luxembourg on Monday.

There is a big drop off after Nadal. Stan Wawrinka is fifth at +1,200, while Juan Martin Del Potro is sixth at +1,400. They are followed by Nick Kyrgios (+1,600), Milos Raonic (+2,000) and Kei Nishikori (+2,200).
