Returning Acapulco quarter-finalist Marcos Giron, who opens against countryman Michael Mmoh, was on hand for the draw ceremony and shared his matches to watch in the opening round.

"I would want to see Mackie, a fellow American, playing against Carlitos," the 29-year-old said. "Carlitos is obviously playing great I think that would be a fun one." McDonald will be bidding to upset a Spaniard ranked at No. 2 in the Pepperstone ATP Rankings for the second time this season after his second-round upset of Rafael Nadal at the Australian Open.

"Also Holger Rune against Ben Shelton, I think that's going to be a really good one," Giron added. "Ben's been playing great, quarter-finals of the Australian Open. Holger is young, in the Top 10 in the world. So I think that's going to be a really good match."

Giron is one off 11 Americans in the singles main draw, not including potential qualifiers, with third seed Fritz and sixth seed Frances Tiafoe leading the way.
