The action is underway in the 2020 ATP World Finals, and while outsiders might look at the event and assume that Novak Djokovic and Rafael Nadal might have the glory to themselves, the reality is far from that assumption.

The betting markets don’t fully reflect it, but the ATP World Finals represent a great chance to bet on the underdog in the Men’s Singles festival, with no-one having won the event by winning every match – and gaining a seven-figure prize as a result – for some years.

This year, the two groups have pitched together, as they always do, the strongest eight players in men’s tennis across the year.

In ‘Tokyo 1970’ Group, Novak Djokovic (23/20) and Daniil Medvedev (4/1) are favourites to make it through to the semi-finals, but Germany’s Alexander Zverev is a tempting 33/1 shot. It’s fair to say that this might not be Diego Schwartzman’s year, with his record in losing to Novak Djokovic in straight sets setting him up for a fall, but the Argentinian has come back from worse, and if he can find a way to beat Zverev, those odds will shrink. It really is a tough ask, however, and ‘Djoko’ would still be a good bet at this point, with the world number one sure to be fired up after a mixed year on and off the court.
