In the battle of the qualifiers, Christopher Eubanks defeated Adrian Menendez-Maceiras 6-4, 7-6 in an hour and 28 minutes for his third ATP victory. Serving at 73%, Eubanks fired 14 aces and he saved three out of five break points, limiting the damage behind the initial shot and breaking the Spaniard three times to prevail in straight sets.
The American hit the zone right from the start of the match, serving well and breaking Menendez-Maceiras in the tenth game for a 6-4. The second set wasn't that fluid and they traded breaks in games four and five before Eubanks repelled three break points in game seven to remain on the positive side of the scoreboard.
Adrian broke him at 15 at 5-5 and he wasted a set point on serve in the following game, suffering a break and allowing Christopher to win the tie break 7-4 and move into the second round where he will face the 7th seed Jordan Thompson.
The Spanish veteran Guillermo Garcia-Lopez beat the young Aussie Alexei Popyrin 7-6, 6-3 in 80 minutes, saving three out of four break points and stealing the teenager's serve twice to secure the place in the last 16.
Popyrin's second serve let him down in the crucial moments but he had the opportunity to win at least a set, pulling a break back in the opener and creating three set points at 6-3 in the tie break. Out of sudden, Garcia-Lopez won five points in a row to steal the set and build the momentum before the rest of the encounter.
The second set saw eight commanding holds on both sides and a break for Guillermo in game six that was enough to push him over the finish line and secure the third win of the season. In the battle of the Canadians, a qualifier Brayden Schnur notched the first ATP win after a 6-1, 6-3 triumph over a Collegiate player Jack Mingjie Lin in an hour and 16 minutes.
Brayden lost 15 points in eight service games, saving all three break points he faced and winning more than half of the return points against a debutant at this level to score four breaks from nine chances. Lin sprayed a backhand error in game three to waste a game point and he dropped serve in the following game when his forehand landed beyond the baseline.
Schnur repelled another break point at 3-1 and he forged a 5-1 lead with another break in game six after a loose slice from Jack Mingjie. Brayden held at love in the seventh game to grab the opener and he controlled the scoreboard in set number two as well, breaking Lin at 15 in game five and again at 5-3 with a volley winner to seal the deal and grab the maiden win on the Tour.
Ryan Harrison defeated Peter Polansky 6-3, 6-4 after a solid performance, losing serve once and scoring three breaks on the other hand march into the second round after just 65 minutes. The last year's finalist Sam Querrey made a winning start after a 7-6, 6-2 triumph against the young South African Lloyd Harris in 71 minutes.
Lloyd had the opportunity to win the opening set, breaking Sam in the 11th game after a forehand error from the American but losing serve in the very next game after a double fault, falling 7-2 in the tie break after a service winner from Querrey.
Sam lost just two points on serve in the second set and he fired a backhand down the line winner in game three to open the gap, securing another break in game seven and blasting four service winners a few minutes later to wrap up the win and face Ivo Karlovic or Radu Albot in round two.
