World No. 1 Novak Djokovic can move one step closer to the Golden Slam on Thursday when he takes on Kei Nishikori in a men's quarterfinal match of the 2020 Tokyo Olympics at Centre Court of Ariake Tennis Park. Djokovic, 34, already has won the first three grand slam tournaments of the year and with a gold medal at the Olympics and a win in the final major, the U.S. Open, he would become just the second player, and first male, to win all four grand slams and a gold medal in the same year. (Steffi Graf pulled off the feat in 1988.) 

The match will start after the conclusion of the first match on Centre Court, which is set to begin at 2 a.m. ET. William Hill Sportsbook lists Djokovic as a -1400 (risk $1400 to win $100) favorite in the latest Djokovic vs. Nishikori odds, with Nishikori listed at +700 as the underdog. Before making any Nishikori vs. Djokovic picks, you need to see the Olympics 2020 picks and predictions from tennis handicapper Sean Calvert.

Calvert is the handicapper who called Stan Wawrinka winning the 2014 Australian Open at 60-1, the last Australian title won by someone other than Djokovic or Federer. In 2019, Calvert took down a huge score on Dominic Thiem winning Indian Wells at 80-1. And earlier this month he nailed both of his bets for the Wimbledon men's singles final: Djokovic to win three sets to one (+275) and Djokovic to win and both players to win a set (+130). Anyone following his picks is way up.

Now, Calvert has analyzed the latest Olympics 2020 odds and released his coveted best bet for Djokovic vs. Nishikori. He's sharing his Olympics picks and tennis analysis only at SportsLine.

Djokovic vs. Nishikori preview

Djokovic has been dominant so far in Tokyo. In three matches at the 2020 Olympics he has not lost a set and has needed just three hours and 37 minutes total to dispatch his opponents. His serve has been broken only once.

In addition, Djokovic has owned the head-to-head matchups against Nishikori. The Serbian is 16-2 against Nishikori and has won 15-straight meetings. Over those 15 matches, Djokovic has dropped just six sets.

But the world No. 1 will face an inspired Nishikori on Thursday. Armed with a devastatingly efficient backhand, the 31-year-old has been excellent in capitalizing on break-point opportunities in the Olympics. In three matches, he has converted on 13-of-23 break-point chances. His 57 percent success rate in Tokyo has far outpaced his rate so far this season on the ATP Tour (38 percent).

In addition, the man from Japan will have the support of the host country behind him. Japanese athletes have excelled so far in the Olympics, winning 13 gold medals (and 22 medals overall). The gold haul already is one more than the team had during the entire 2016 Summer Games in Rio de Janeiro.

How to make Djokovic vs. Nishikori picks

Calvert is leaning over 19.5 total games, but he has an even stronger play, which would pay plus-money. Be sure to check out Calvert's picks and analysis before making your Olympics 2020 picks for the men's quarterfinal.
