1. (1) Nicolas Mahut/Pierre-Hugues Herbert (FRA) vs. Rober Farah/Juan-Sebastian Cabal (COL):
When the number one and two doubles players in the world pair up, you can't expect anything less than domination. The 2016 Wimbledon doubles champions are looking to win gold at this year's Olympics, and with the way they've been playing this year, I would expect nothing else.
2. Jack Sock/Steve Johnson (USA) vs. Julio Peralta/Hans Podlipnik-Castillo (CHI):
With the Bryan Brothers out of the doubles draw, the next best men's american doubles team is Sock/Johnson. Sock has had a decent amount of success in doubles, winning the 2011 US Open Mixed Doubles title with Melanie Oudin, and the 2014 Wimbledon Men's Doubles title with Vasek Pospisil. Sock/Johnson are capable of upsetting some big dogs, which they will have to do in order to go far in this Olympic draw.
3. (3) Bruno Soares/Marcelo Melo (BRA) vs. Sanchai Ratiwatana/Sonchat Ratiwatana (THI):
The number eight doubles player in the world, who typically partners with Jamie Murray in the grand slams, is bringing his doubles expertise to this Brazilian team. I see them going far in the draw, and getting through this first round no problem.
4. (6) Rafael Nadal/Marc Lopez (ESP) vs. Robin Haase/Jean-Julian Rojer (NED):
All eyes will be on Nadal in this matchup to gage how his health progresses since he is playing three events in Rio. Haase/Rojer is not a team to take lightly, and getting through this section of the draw will be tough for either team. I'll pick Nada/Lopez, but it'll be close two set win.
5. (4) Gael Monfils/Jo-Wilfried Tsonga (FRA) vs. Brian Baker/Rajeev Ram (USA):
No one on this court is a rookie. The French team of Tsonga/Monfils is the most entertaining team in the draw, and I'm looking forward to watching their big personalities together on court. The veteran team of Baker/Ram are the underdogs in this match, but they'll put up a good fight. I'm taking Monfils/Tsonga in three.
6. (2) Andy Murray/Jamie Murray (GBR) vs. Thomas Bellucci/Andre Sa (BRA):
It's time for the Murray Brothers to shine! Although they had a disappointing loss in 2012 at London, I think they've both matured and will come together to be a dominating force in Rio. I don't see them having any trouble in this first round match, and expect them to go far.
