It has been a great week for the John Deere Classic golf tournament near the Quad Cities. Sunday, title known Ben Curtis, a John Deere entrant, shocked the world by winning the British Open. Today, the tournament landed one of the world’s top golfers as Vijay Singh committed to take part. Singh has won two majors and is ranked third in the world.Tournament director Claire Peterson says the field is shaping up to be the best in tournament history. He hopes more of the big names will decide to compete. He says it adds more credability to have someone like Singh join the field.Peterson says he had no idea who Ben Curtis was or that was schedule to play the John Deere until after his win on Sunday. He says he quickly checked the list as Curtis won and found he was on it. Peterson says the move to September has helped the tournament which used to be held the week after the British Open. He says it’s difficult because the top players are traveling back from Brittain and are fatigued from the trip and don’t want to play again right away. The tournament is September 8th through the 14th.
