Scottie Scheffler turned down one fan's request for an autograph after he was asked to sign a Boston Celtics hat.
Scheffler grew up in Dallas and watched the Mavericks suffer defeat by Boston in this year's NBA finals.
To rub salt in his wounds, the world No 1 is now preparing to play at the Travelers Championship - in New England.
The Texan was asked during a press conference on Wednesday if he was expecting trash talk during the tournament in Connecticut.
'I did get one fan today ask me to sign a Celtics hat, and I told him no,' Scheffler said with a smile. 'But other than that, not much interaction.'

On whether other players - such as Vermont-native Keegan Bradley - would roast him, he added: 'Probably not from other golfers.
'Maybe Keegan (Bradley), but probably not... I wouldn't really expect that out of him.'
Scheffler is hoping to bounce back after a disastrous US Open at Pinehurst, when he barely made the cut.
The world No 1 was a strong favorite last week, after claiming his fifth victory of the season at the Memorial Tournament a fortnight ago.
But the 27-year-old finished 14 shots behind winner Bryson DeChambeau after carding his fifth successive over-par round.
'I didn’t really think about it very much when I was shooting under par, so I’m probably not going to think about it too much when I’m shooting over par,' he said.
'It’s just one of those deals, like when I was playing good and I was able to survive the harder golf courses. It’s just kind of (one of) those weird little stats. It’s not like I played that bad and shot over par.'
