Couples made his debut on the Champions Tour at the opening event of the 2010 season, the Mitsubishi Electric Championship in Hawaii. He nearly won the tournament, finishing second to Tom Watson. Despite the loss, Couples stated, "I had a wonderful time. I think I was 21 under par and didn't win a tournament. That hasn't happened too many times." Had he won, he would have become the 16th player to win his Champions Tour debut. He won his next three starts, The ACE Group Classic, the Toshiba Classic and the Cap Cana Championship, becoming the first player in Champions Tour history to win three of his first four career events. Couples made another run at the 2010 Masters Tournament but finished 6th. It was his 26th top ten finish in a major tournament.
