Five Matches To Watch: Day 2
 Christina McHale vs. Genie Bouchard
Both McHale and Bouchard are known for their capacity to grind out a baseline battle. It will be the first meeting between these two, making the high temperatures and humidity the only sure thing when they take the court at 1:50.
 Kristina Mladenovic vs. Tatjana Maria
Mladenovic, a newly minted top-15 player, holds a 3-1 record over Maria, but the 29-year-old German is experienced and crafty. She could test the big-hitting Frenchwoman, especially as both players are heading out for their first hard-court match of the summer season.
 Alexander Zverev vs. Jordan Thompson
He’s been hailed as the next big thing and, so far, eighth-ranked Zverev has backed up his big-time billing. Thompson, who upset world No. 1 Andy Murray during grass court season, is also in the midst of a career-best season, rising to a rank of No. 63 in the world earlier this year. Expect these two young players to put on a show.
 Grigor Dimitrov vs. Kyle Edmund
Grigor Dimitrov has captured two titles this season, briefly reentering the top-10 after being ranked No. 40 in the world this time last year. At just 22, Edmund is having the best season of his career, reaching two quarterfinals to start 2017 and making a run to the Atlanta semifinals just last week. This should be a fun one.
 Nick Kyrgios vs. Tennys Sandgren
Tennys Sandgren has already won the tennis name game. When he takes the court late on Wednesday night, the question will be whether or not the 26-year-old American can tack another big victory onto his summer hot streak. The world No. 106 will face a hobbled Kyrgios, who has not won a match since reaching the second round at Roland Garros. Even if the Australian’s pesky hip injury has healed, he’ll likely have some rust to shake off as he starts his 2017 hard-court campaign.
