CROMWELL, Conn. (AP) — Nathan Grube, the tournament director of the Travelers Championship, used to worry about the years when the U.S. Open took place on the West Coast. Many of the world's top golfers would make a decision to take a break the week following the major or head to Europe to begin preparing for the Open Championship, rather than travel across the country to play at TPC River Highlands in Connecticut. But this year, in response to LIV Golf, the Travelers was elevated to one of 17 so-called “designated” PGA Tour events, with a much bigger purse and a near mandate for top golfers to play, giving the tournament the guarantee of a strong field.
