Friday’s ATP Finals tips: Cilic, Isner and Zverev eye semi-final spot

Preview and odds for today’s matches

The final batch of ATP Finals group matches take place today, with three players fighting over the remaining semi-final spot.

Novak Djokovic is already through in the Gustavo Kuerten group, after winning his opening two matches.

He plays Marin Cilic tonight, with the Croatian needing a win to go through. But if Alexander Zverev defeats John Isner in straight sets, Cilic’s hopes will be over.

Alexander Zverev v John Isner

German youngster Zverev is 2/5 to defeat John Isner, and with good reason too.

The 21-year-old has won four of his last five meetings with the American, so he isn’t fazed by Isner’s famed serve.

Isner is 2/1, and could yet go through if he wins well and Djokovic then beats Cilic. But Zverev was impressive against the similarly-heavy hitting Cilic earlier this week, and should have the edge again today.

There’s 11/10 about Zverev to grab the straight sets win he needs to progress. But Isner is sure to take a few games on his own serve. It’s 4/1 for the first set to end 6-4 in Zverev’s favour.

Novak Djokovic v Marin Cilic

Novak Djokovic is already through, but the Serbian has been playing superbly in London this week, and is unlikely to ease off and risk losing momentum.
