William Hill have boosted the odds on Rafa Nadal beating Juan Martin Del Potro 3-1 at the French Open from 13/5 to 10/3 and Delpo’s past record against the Spaniard makes it a particularly appealing wager.

Nadal leads the pair’s career head-to-head 9-5, so you already know his lanky foe has the ability to get a lot more than a set out of him when at his best.

However the undisputed king of the Roland Garros clay has also won each of the pair’s last three best-of-five-sets showdowns by, you guessed it, three sets to one.
