Twenty-year old amateur Lewis created history in sharing the lead after the opening day of the 140th Open Championship.

Lewis, a native of Welwyn, England, opened his first Open Championship with a 5-under 65 – the lowest round by an amateur in Open history.

Prior to Thursday, the lowest round by an amateur at The Open was 66, recorded by Frank Stranahan in 1950 (R4), Tiger Woods in 1996 (R2) and Justin Rose in 1998 (R2).

The last amateur to lead The Open after any round was Michael Bonallack, who shared the opening-round lead with Brian Barnes after matching 70s at the 1968 Open Championship at Carnoustie.

Mike Reid was the last amateur to lead a Major Championship, doing so by three strokes after the first round of the 1976 U.S. Open.

Three amateurs have won The Open a total of six times:

            Bobby Jones                 3         1926, 1927, 1930

            Harold Hilton                2         1892, 1897

            John Ball Jr.                   1         1890

Here’s a look at the youngest winners at The Open:

Tommy Morris Jr.         1868     17 years, 5 months, 3 days

Willie Auchterlonie      1893     21 years, 24 days

Seve Ballesteros            1979     22 years, 3 months, 12 days

Lewis won the 2009 Boys’ Amateur Championship at Royal St. George’s.

Lewis was named after five-time Open winner Tom Watson and the pair were grouped together on Thursday, with Watson carding a 2-over 72.

Henrik Stenson rounded out the group with a 2-over 72.
