The top two golfers in the world will get an up-close look at one another after Jason Day and Jordan Spieth were paired together for The Players' Championship.
World number one and two, Day and Spieth, will play in the marquee grouping at TPC Sawgrass in Florida, with 11th-ranked Branden Grace rounding out an impressive trio.
The group is set to tee off at 08:43 local time (12:43 GMT) on Thursday May 12 in the opening round of the tournament, which is largely considered as golf's fifth major.
While Day and Spieth have been paired atop the world rankings for some time, each will have something to prove this week.
Both players missed the cut at last year's event, with Australian Day shooting an uncharacteristic 81 on Friday.
Rory McIlroy, Bubba Watson and Dustin Johnson - all in the top 10 in the world - will tee off later in the afternoon, as well as the trio of defending champion Rickie Fowler, Adam Scott and Matt Kuchar.
Former champions of the tournament Phil Mickelson (2007), Henrik Stenson (2009) and Martin Kaymer (2014) will tee off just before the Day, Spieth and Grace trio in the morning.
