European Tour players will incur a one-shot penalty from November if they are deemed to have breached slow play regulations twice in a single round.
In addition, players who consistently need to be timed or are “on the clock” will face stiffer fines from next season.
For example, a player who is timed on 15 occasions during a season will be fined £26 000, as opposed to the current £9 000 fine in place.
Players will, however, have the option to request one time extension per round, giving an additional 40 seconds to hit a shot.
“We are already at the forefront of pace of play management in the professional game, but after being mandated by our Tournament Committee to be even firmer in dealing with this issue, the time was right to take these additional steps,” European Tour chief executive Keith Pelley said in a statement.
