Jason Day, Jordan Spieth and Rory McIlroy, the top three in the world golf ranking, are all going to Muirfield Village for the Memorial coming off victories.
The second-ranked Spieth won Sunday at Colonial for his eighth PGA Tour victory and first in his home state of Texas.
Day, the world's No. 1 player, hasn't played since winning The Players Championship two weeks ago. McIlroy took a short break after winning his home tournament at the Irish Open last week.
"For me, it's big just to take a big step and a small chunk into Jason's lead right now," Spieth said. "I knew there was a large gap. I had been told before last week that had I won last week (at the Byron Nelson) and this week, I still wouldn't take over, which just speaks to what Jason has been able to do."
The Jack Nicklaus-hosted Memorial starts Thursday in Dublin, Ohio.
