Pablo Carreno Busta (ESP) vs Diego Schwartzman (ARG) – An all-Argentine and an all-Spanish final is possible. I have doubted Schwartzman at every turn so in a kiss of death, I am picking him to win this match.
 Sam Querrey (USA) vs  Kevin Anderson (RSA) – Querey won in Mexico after reaching the Wimbledon semifinal round. Querrey was up a break in the 4th set vs. Cilic at Wimbledon. It looked like he might be one set from a major final. Now, Querrey is 6 sets away from a major final. He looks to be the form horse of these 4 quarter finalists and is the only one of them to reach a major semifinal. Anderson can win this match and did beat Andy Murray at the US Open in 2015. I don’t think Anderson will be overawed by the opportunity ahead of him. I expect a lot of service holds from each man, but as I stated earlier, Querrey has a lot of good wind at his back.
A dominant Sam Querrey is into the #USOpen last eight.
