Portrack Shamrocks F.C.

The club was founded in 1921,^[1] originally under the name Stockton Shamrocks, changing to Portrack Shamrocks before the 1932–33 season. For much of its existence, the club's chief backer was comedian Jimmy James.^[2] Many of the club's players came from the Stockton Malleable ironworks.^[3]

Its greatest successes came in Teesside football, winning the Teesside Football League in 1949–50 and 1955–56, and the equivalent knockout competition - the Macmillan Bowl - in 1947–48, and three times in a row from 1954–55 to 1956–57.^[4] The club also won the Ellis Cup, which had started out as the South Bank Amateur Challenge Cup, in 1952–53, having been runner-up in 1938–39 and 1944–45. It also won the wartime North Riding Senior Cup in 1940, beating South Bank East End at Ayresome Park.^[5]

On a national scale, the club reached the 3rd qualifying round of the FA Cup three times between 1946 and 1950.^[6] It entered the FA Amateur Cup from 1924–25 to 1953–54,^[7] its best run being to the second round proper (last 32) in 1927–28 and 1933–34. Its 1–0 win over its larger neighbours Stockton in the 1933–34 edition was considered a major shock;^[8] in the second round it lost 1–0 at Worcestershire side Badsey Rangers.^[9]

The last recorded game for the club was in April 1957,^[10] and it seems to have been dissolved before the 1957–58 season.

The club wore white shirts with a green shamrock badge^[11] and black shorts.^[12]

The club's ground was known as Portrack Grange,^[13] and was known as Paddy's Field.
