They’ve only played singles four times — not often given that Serena Williams is 34 and Roberta Vinci is 32. But the last of those matches was just last month when Serena Williams beat Roberta Vinci 6-4, 6-3 in Toronto. Closer than you might expect, right? Well it was closer than Williams expected too: she admitted as much, saying “[Vinci] played me really tough… she knows what to do.”
But oddsmakers make Williams a favorite by an extraordinary margin: the moneyline on the match for those wagering on Williams is -2000. That means you’d have to bet $2,000 on Serena Williams to win just $100. If you’re really in a gambling mood you can put $100 on Vinci; if she wins it’ll pay you $1100.
