Blowick, Southport, Lancashire born inside forward Billy Glover began his football career with St Paul’s of Southport in 1912 and played for Maple Crescent in 1913 and Blowick Working Lads in 1914 before the outbreak of the First World War. After the War he joined Lancaster Town in 1919 before joining hometown club Southport in November 1920. When Southport joined The Football League in August 1921, Glover scored their first ever goal in their inaugural League match that August in a 1-1 draw against Durham City. He top scored in their first season with an impressive 28 goals during the campaign, including an incredible 6 goals in a 7-1 win over Grimsby Town in October.
After a further 9 goals in the first half of 1922-23, he was transferred to Wigan Borough for a fee of £1,250 in January 1923 after 60 appearances for The Sandgrounders. In his sixth match for Borough he scored 4 goals as Wigan beat Lincoln City 9-1 in March. At Springfield Park he was a regular if not prolific goalscorer over the next three seasons. He was Wigan’s top scorer in the 1924–25 season, with a total of 15 goals, including a hat-trick in a 4-1 win over Rotherham County in March 1925, but he broke his leg in the penultimate game of the season against Grimsby Town. He played twice during the following season, but never fully recovered from the injury, effectively ending his career at the professional level. He re-joined Southport in August 1926 after 35 goals in 99 appearances for Wigan, but never appeared in their first team. He finally joined non league Mold Town later in 1926 and finished his career joining Burscough Rangers the following year.
