Here are the available highlights of the match, which Harrison won, 6-3, 7-6 (4). You'll see the altercation, without clear audio, just after the two-minute mark:
Harrison did not get into any specifics about the argument during a post-match interview, explaining it as chatter during the moment of competition, and nothing more:
At 12:03 a.m. on Tuesday morning, Young, an African-American player, tweeted his thoughts about the incident:
I’m shocked and disappointed, Ryan Harrison, to hear you tell me how you really feel about me as a black tennis player in the middle of our NY match. I thought this was supposed to be an inclusive gentleman’s sport.— Donald Young Jr (@Yimlife1313) February 13, 2018
Shortly after, Harrison tweeted that Young's accusations were "absolutely untrue," and that he would be cleared by available audio and video of the event:
The accusations made by Donald Young tonight following our match are absolutely untrue. I’m extremely disappointed that someone would say this in reaction to a lost tennis match. Any video/audio will 100% clear me and I encourage anyone with the available resources to find it.— Ryan Harrison (@ryanharrison92) February 13, 2018
Earlier this morning, Eleanor Crooks of the Press Association tweeted the ATP's response to the altercation, saying that the organization is reviewing "allegations of racial prejudice":
ATP response to Young/Harrison: ‘The ATP takes any allegations of racial prejudice extremely seriously. A further review of all video and audio recording from the match will take place as this matter is investigated further."— Eleanor Crooks (@EleanorcrooksPA) February 13, 2018
Tennis Channel's Jon Wertheim confirmed that the ATP is investigating the matter, and added that Young and Harrison could meet each other at the tournament once again, in doubles:
Told that ATP is investigating ...stay tuned. Tennis being tennis, Harrison and Young are a round away from meeting in doubles. https://t.co/w4j8lNCpj2— Jon Wertheim (@jon_wertheim) February 13, 2018
The Associated Press' initial report about the New York Open did not mention the incident. We'll update this if further updates come in.
UPDATE: The ATP has released a statement on the matter.
NEW YORK (AP) — The ATP says it is reviewing accusations by Donald Young that Ryan Harrison used racially inappropriate language when the Americans had a heated exchange during their opening-round match at the New York Open.
"The ATP takes any allegations of racial prejudice extremely seriously," the organization said in a statement. "A further review of all video and audio recording from the match will take place as this matter is investigated further."
Harrison defeated Young 6-3, 7-6(4) on Monday night, and at one point during a changeover the two appeared to be arguing, the chair umpire moving in between the players to attempt to calm the situation.
Young posted on Twitter after the match : "I'm shocked and disappointed, Ryan Harrison, to hear you tell me how you really feel about me as a black tennis player in the middle of our NY match."
Harrison responded on Twitter that the allegations were "absolutely untrue" and audio from the match would "clear me."
Am hearing the ATP has found no evidence to support Donald Young’s claim that Ryan Harrison made a racial comment toward him.— David Waldstein (@DavidWaldstein) February 13, 2018
