Tom Lewis, born on 5^th January 1991, is a professional golfer from Welwyn Garden City, Hertfordshire, England.

Lewis started his golfing career as an amateur and in 2009 he won the Boys Amateur Championship at Royal St George’s. At the New South Wales Open in 2010 he lost to Peter O’Malley in a playoff and later that year finished a tied 12th place at the Australian Open. In 2011 he earned another victory on the Old Course at St Andrews in the 2011 St Andrews Links Trophy.

Tom Lewis qualified for the 2011 Open Championship at Royal St George’s via Local Final Qualifying at Rye. In the first round he shot a five-under-par 65, giving him a share of the lead alongside Thomas Bjørn. This was the lowest single-round score by an amateur in Open Championship history, and the equal lowest in any major championship. It made him the first amateur to lead a major after a round since Mike Reid in the 1976 U.S. Open and the first amateur to lead the Open Championship since Michael Bonallack in 1968. One of Lewis’s first-round partners was Tom Watson, after whom he is named. Lewis finished tied for 30th place and as the low amateur, he won the Silver Medal.

Lewis turned professional after the 2011 Walker Cup. He made his professional debut at the Austrian Golf Open in September 2011, shooting a two-over-par 74 in the first round. He recovered to finish in a tie for tenth.

Tom Lewis won his maiden professional tournament at the Portugal Masters on the European Tour in October 2011, shooting rounds of 70, 64, 68, and 65 to finish two shots clear of the field. It was his third professional start. In December 2011 he was crowned the European Tour’s Sir Henry Cotton Rookie of the Year.
