Exactly two weeks after announcing Rory McIlroy would play for the first time, the Travelers Championship announced Friday that former champions Bubba Watson and Russell Knox have joined him.

Watson won the event in 2010, his first victory on the PGA Tour, and in 2015. He was ranked as high as No. 4 last year but now the former two-time Masters champion is 16th in the world rankings.

Knox, currently 21st in the world rankings, birdied the 18th hole last year to win the championship at TPC River Highlands in Cromwell. It was Knox’s second victory on Tour.

Tickets for this year’s event, to be held June 22-25, go on sale Wednesday. For more information on this year’s tournament, visit www.TravelersChampionship.com.
