The Heroes Classic, a new showcase event at The 154th Open, will see some of the biggest names compete alongside a host of special guests at Royal Birkdale.
The event takes place on Tuesday, 14 July - two days before the opening tee shot at golf's original championship - with Practice Day tickets still available.

Jordan Spieth and Padraig Harrington, both Champion Goflers at Royal Birkdale, will join AIG Women's Open Champion Miyu Yamashita, G4D Open Champion Brendan Lawlor and European Ryder Cup stars Justin Rose and Tommy Fleetwood.
High profile figures from sports and entertainment, and R&A ambassadors, including Bryan Habana and Kathryn Newton will also tee it up at the Heroes Classic.
The Heroes Classic will be contested in teams of three players over the 1st, 2nd and 9th holes at Royal Birkdale.
A Texas Scramble format will be used with a scoring incentive to ensure each participant gets to hit as many shots as possible, creating team unity and enabling friendly competition.
The R&A once again experienced huge demand from fans in the ticket ballot for The 154th Open at Royal Birkdale meaning that almost all tickets across the week are sold out.
However increased capacity has resulted in a limited number of tickets being available to attend Practice Days which include the Last-Chance Qualifier on Monday 13 July and the Heroes Classic on Tuesday 14 July.
Fans can enhance their experience with Ticket Plus, offering general admission plus access to a private area featuring exclusive food and drinks, indoor and outdoor seating, a big screen, private restrooms, a £25 food voucher and a private bar.
