According to an article I saw on ESPN, a Euro tour event this year will introduce a shot clock, with 1-stroke penalties for failing to hit a shot within the alotted time.
Every player will be timed on every shot in Austria. The other big difference from GolfSixes is that the event will use the Tour’s official timing policy. Each player in the 120-man field will have 50 seconds for the first player in a group, with 40 seconds for subsequent players. A one-shot penalty will be handed out to players going over the time limit, and a red card will appear beside their name on the leaderboard.
The Tour is hoping to cut three-ball timings down to four hours, and two balls down to three hours and 15 minutes.
