Rafael Nadal has been cut to 9/4 to win the French Open after winning his 9th ATP Barcelona title on Sunday.
The Spaniard's 6-4 7-5 victory over Kei Nishikori made it back-to-back titles following last week's triumph in Monte Carlo and suggests the Spaniard is back to form ahead of his bid for an unpredented 10th French Open crown in Paris next month.
Nadal is the second favourite to triumph at Roland Garros, where Novak Djokovic will be the favourite but the world number one is now 41/50 after his early exit at the hands of Jiri Vesely in Monte Carlo.
Victory capped a stunning fortnight for Nadal, who has struggled for form since taking seven months out because of a knee injury, and withdrew from last month's Miami Open due to a virus.
"I'm very happy because besides this being one of the most important tournaments that I have won, this is another week that I am playing very well," Nadal said. "These have been two fantastic weeks, weeks I have been striving for for a long time."
Nadal is the 4/5 favourite to secure back-to-back titles when the ATP Tour moves on to Barcelona this week. With Djokovic not competing, Nadal will be the man to beat but Kei Nishikori, second in the betting at 13/5, is looking to complete a hat-trick of titles in this event.
His 2014 success ended home dominance of the tournament, with a Spaniard having won the 11 previous events stretching back to Carlos Moya in 2003. Nadal won eight of the nine Barcelona Opens between 2005 and 2013.
