Today Zverev (odds 48.72) lost half-final not with Nadal (6.35) but with his health. And in few moments we will know the second player for the final, Ruud (43.07) plays against Cilic (76.28, Other!).
Even if Nadal win the main prize, odds >6 make a big win for everyone who placed the bet.
I cannot imagine that Rolland Garros would be won by someone with odds >40, but it would be really really great. 183 people who bet on Ruud or 251 who bet on "Other" will remember it for long.
He's now the big favorite of the final with odds of @1.2 against @5.0 for Casper Ruud on other sportsbooks then I hope he will manage to win his 14th Roland Garros.
