Their only previous clash came in 2022, an ATP Challenger-level match in Fairfield, which the Canadian won in three tightly contested sets.Following his win over McDonald, Shelton made it clear that he wanted to feature in as many competitive encounters as possible before he begins his campaign at this year's US Open, saying:"It's really important, I think just (with) where I want my match count to be going into the US Open, to start off strong here and be playing again on Thursday and get myself a chance to have a second match. I think that the way these courts play at nighttime is fairly similar to the way the US Open plays during the day. During the day here, it's faster. But I think that getting as much exposure as I can with this ball and this court is really important."Shelton reached the semifinals of the 2023 US Open, but eventually had to settle for a last-four finish, as he was ousted from the prestigious hardcourt Major by eventual champion Novak Djokovic.
