"It's always special to come here and win at St. Andrews," said Harrington, who trailed Dredge by one entering the round, but erased that deficit with a 10-foot birdie putt on the first hole. "The first time I won here four years ago it was a little bit tighter. This was the first time I could walk down 18 and enjoy it."
Harrington made his move at No. 9, when he dropped in a 12-foot birdie putt to join Dredge at 14-under.
