Tyrrell Hatton recovered from the disappointment of Europe's heavy loss at the Ryder Cup last week as he took a share of the first-round lead at the Alfred Dunhill Links Championship on Thursday.
Each player in the 168-man field plays a round at all three venues, before the final round takes place at St. Andrews on Sunday.
Playing traditionally the toughest of the three courses that stage the tournament, Hatton shot 8-under 64 at Carnoustie to tie for the lead with Nicolas Colsaerts, Adri Arnaus (both St. Andrews) and Li Haotong (Kingsbarns).
Hatton has twice won the championship, claiming his first title as a professional at the tournament in 2016 and again in 2017.
The Englishman was a member of the European team beaten 19-9 by the United States at the Ryder Cup at Whistling Straits, the biggest margin of victory since Europe became part of the event in 1979. Hatton claimed 1½ points for Padraig Harrington's team, with only Jon Rahm and Sergio Garcia getting more.
Tommy Fleetwood, who also played for Europe last week, shot a bogey-free 66 at Carnoustie and was tied for eighth place, two strokes back.
Five of the Top 10 played at the Old Course at St. Andrews, which is typically where the best scores are made.
