The Travelers Championship is one of the bigger golf tournaments that is not considered to be in the grand slam category in the sport.

The 2020 event will be totally different from past tournaments. The TPC River Highlands Course in Cromwell, Conn., will feature no fans due to safeguards amid the coronavirus pandemic.

The event this week will feature some of the best fields in the tournament’s history. Bubba Watson, Phil Mickelson, Jordan Spieth, Rory McIlroy, Jon Rahm, Justin Thomas and Dustin Johnson are expected to be golfing.

The tournament is also working with the Hartford Foundation for Public Giving to help to build positive relationships between police officers and African-Americans and other communities of color.

Brooks Koepka and Webb Simpson pulled out over COVID-19 fears.

Who are the favorites to win the Travelers? Rory McIlroy (+1200), Justin Thomas (+1200), Bryson DeChambeau (+1200), Jon Rahm (+1800), Patrick Cantlay (+2200) and Dustin Johnson (+2500).

What to look out for? Alex Donohue, a sports betting industry expert at Bet-NJ.com, says to keep eyes on Bryson DeChambeau during the tournament.

“Bryson DeChambeau has delivered on his promise to put on muscle and comes into the PGA Travelers Championship off the back of good form in his two outings since lockdown, owing to the accuracy of his tee shots. Oddsmakers predict this weekend's event will be a paradise for the big hitters and DeChambeau's form as well as his change to a 5.5-degree driver, as opposed to most using a 9-10.5, is why he is joint-favorite to win,” Donohue says.

“DeChambeau was 27/1 to win this tournament 12 months ago.

“Oddsmakers are preparing themselves for a high-odds winner because of the unique way the tournament has been priced. Form plays a huge part in a player's odds and the recent break means a player may play much better than oddsmakers expect.”
