Jannik Sinner was labelled an "artificial intelligence" player by opponent Alexander Bublik after the defending US Open champion ruthlessly raced into the quarter-finals.
World number one Sinner needed only one hour and 21 minutes - the second-quickest win in the men's singles this year - to beat Kazakhstan's Bublik in a 6-1 6-1 6-1 victory.
Within minutes of his defeat, 23rd seed Bublik wrote 'AI' in a comment on the US Open's Instagram post about the result - reiterating the description he made about Sinner going into Monday's fourth-round match.
Bublik is one of only two men to beat Sinner this season, but the 24-year-old Italian ensured there was no chance of a repeat with a ruthless performance in New York.
