Seamus Power and Graeme McDowell will be looking to take a big step into the summer in the Charles Schwab Challenge at Colonial.
McDowell is determined to qualify for The Open and with the top five and ties (not already exempt) inside Top 20 in the FedExCup on June 23 winning exemptions, victory at Colonial could seal his ticket home to Royal Portrush.
He was 29th in Texas last year and he's relieved that he will not face the same driving test he did at Bethpage Black in last week's US PGA.
"I knew I was going to have a very tough time competing against the likes of Brooks Koepka, Dustin Johnson and Rory," McDowell said after also finishing 29th at Bethpage Black last Sunday. "It was always a golf course where I was going to run into a brick wall."
It's also a chance for Seamus Power to build on recent top 20 finishes and make sure he heads to Lahinch for the Dubai Duty Free Irish Open with his PGA Tour card secure.
"That was one of the things Paul McGinley spoke to me about," said Power, who is 108th in the FedExCup standings with the top 125 keeping their cards. "You know, get playing well over there so you have some points in the bag and you can enjoy the experience much more.
"I was lucky I was able to do that last month and hopefully I can keep it up before coming home to Ireland and if I am in good form, getting myself into contention in Lahinch."
The field at Colonial includes 18 of the world's top 50 with defending champion Justin Rose, Francesco Molinari, Bryson DeChambeau, Xander Schauffele, Rickie Fowler and a resurgent Jordan Spieth some of the leading lights.
On the European Tour, England's Matt Wallace in the favourite for the Made In Denmark at Himmerland, where Paul Dunne, Gavin Moynihan and Michael Hoey are also in action
Paul McGinley and Darren Clarke make their debuts in the KitchenAid Senior PGA Championship at Oak Hill Country Club in New York where John Daly will ride in a cart for the second week running.
McGinley (52) tees it up with Daly, who was stung by media criticism of the decision to allow him to use a buggy at Bethpage Black under the Americans with Disabilities Act (ADA).
"What really pisses me off is people downing guys, downing women who have ADA problems," said Daly, who suffers from arthritis in his knee and allowed to use a cart
"Because if you don't know what ADA is, it honestly sucks. I felt embarrassed driving a golf cart in a major. That major. But, I want to play and I want to be competitive and the only way I can do it is in a golf cart."
O the Challenge Tour, Paul McBride, Conor O'Rourke, Ruaidhri McGee, Robin Dawson and Cormac Sharvin play the D+D REAL Czech Challenge at Kaskáda Golf Resort.
