Jordan Spieth, the world’s sixth-ranked player, committed to the tournament Thursday morning for the first time. That’s three in the top six, joining No. 2 Rory McIlroy, also committed for the first time, and No. 3 Jason Day.

The tournament will be held June 22-25 at TPC River Highlands in Cromwell.

Spieth is only 23, but has already won nine times on the PGA Tour, including the AT&T Pebble Beach Pro-Am in February. He won his two majors, the Masters and U.S. Open, in 2015, when he also won the Tour Championship, the FedExCup title and was the top-ranked player in the world.

Travelers also boasts Justin Thomas, a three-time winner on Tour this year and the 13th-ranked player, and No. 18 Patrick Reed, along with two-time champion Bubba Watson, Jim Furyk and former winners Marc Leishman and defending champion Russell Knox.
