The 2018 Zurich Classic of New Orleans format is slightly changed from 2017, the first year the tournament went from an individual event to a two-man team competition.
The Zurich Classic field is 160 players as 80 teams of two. The top 80 players in the PGA Tour's priority ranking that committed to the field got to pick their partner, so long as they had some kind of PGA Tour status or garnered a sponsor exemption.
The Zurich Classic format is still a 72-hole event. The first and third rounds will be played as best ball (fourballs) at TPC Louisiana. The second and final rounds will play under alternate shot (foursomes) rules. A 36-hole cut will be made down to the top 35 teams and ties. A sudden-death playoff to settle any ties after 72 holes will be played under rules with format alternating on each hole (fourball to start, foursomes next, and so forth).
The players on the winning team will each get a two-year PGA Tour exemption and spots in the PGA Championship, The Players, the Tournament of Champions and other invitational events. The team members will split the FedEx Cup points normally distributed for individual events, meaning the winning team will split the 500 points for first place and 300 points for second place -- or 400 points per player.
