Lewis, a 54-year-old financial manager from Alma, Mich., will attempt to become the oldest U.S. Mid-Am champion when he faces Kenny Cook, a 6-and-5 winner over John Engler, in Thursday’s 36-hole final.
Smith, 33, was attempting to become the first USGA male golfer to win three consecutive national titles since Tiger Woods won three straight U.S. Amateurs in the 1990s. He tied Lewis by sinking an eagle putt on the par-5 18th. He hit an errant drive on the first extra hole, though, and Lewis sank a birdie putt to win the match.
