The PGA Tour has announced four more "elevated" events for the new season that will see increased prize money and fields guaranteed to feature the world's best players.

The Phoenix Open, RBC Heritage, Wells Fargo Championship and Travelers Championship will now all have $20million (£17.8m) prize purses meaning there are now 17 elevated events throughout the course of the current season.

The other 13 elevated events are comprised of the four majors, the Players Championship, the three FedEx Cup Playoff events, the Genesis Invitational, the Arnold Palmer Invitational, the Memorial Tournament, the WGC Match Play and the Tournament of Champions.

The idea of elevated events was initially developed in August in collaboration with numerous high-ranking golfers after several high-profile PGA tour golfers left to join the Saudi-backed LIV Golf series.

The invitational series offers lucrative signing bonuses that vastly outweigh potential PGA tour prize money winnings and has secured the services of current Open champion Cameron Smith as well as two-time major champion, Dustin Johnson.

But it is hoped these elevated events, which the PGA Tour's top stars are committed to playing, will dissuade more players from leaving in the future and ensure the best players play together more frequently.

The four newly announced elevated events are only for 2023; the expectation being that other events will be given elevated status in the coming seasons.

There is also potential for events in Europe on the DP World Tour to be given elevated status as part of the "strategic alliance" with the PGA Tour.

The Scottish Open, which is co-sanctioned by both tours, could well be one event given elevated status as part of this alliance in future seasons.
