Ivan DODIG & Franko SKUGOR
VS
Leonardo MAYER & Guido PELLA
This match is likely to decide the winner. I could see Croatia sweeping the Day 3 singles matches, but Argentina almost certainly needs this point. I rarely predict doubles matches due to not knowing enough to say X is more likely than Y with any confidence. It is possible each captain could substitute players into this match as well. That makes a prediction quite difficult.
My prediction will be quite simple. I think Croatia has a favorable crowd and a surface that was hand picked. This likely gives Croatia a slight edge entering this match. I predict Croatia to win the doubles point in 4 sets and also expect at least one captain to make a move away from the originally slated line-up.
