Rickie Fowler, Lee Westwood, Ian Poulter, Jason Dufner, Freddie Jacobson and Padraig Harrington have all committed to the Travelers Championship, the tournament announced on Tuesday.
"Along with being great golfers, these six individuals are all well known and our fans will be thrilled to see them compete in person," tournament director Nathan Grube said. "Our competitive field just got a lot stronger with these additions."
All six have played in the event before, which will take place at TPC River Highlands June 20-23, the week after the U.S. Open at nearby Merion Golf Club in suburban Philadelphia.
Jacobson won the Travelers in 2011, while Harrington tied for fifth in 2011 and was 11th last year.
Others already committed include Bubba Watson, Hunter Mahan, Keegan Bradley, Justin Rose, Zach Johnson, and defending champion Marc Leishman.
