1889–90 was the fifth season for St. Mary's Football Club (St. Mary's F.C.) based in Southampton in southern England. The club retained the Hampshire Junior Cup for the third consecutive year.

Summary of season

The season saw the club move into the Antelope Ground which would be their permanent home for the next seven years. They also changed their strip, playing in cherry red squares rather than a white shirt with a red sash.

Although they were qualified to enter the Hampshire Senior Cup, the club committee decided to re-enter the Junior Cup, with a view to winning it for the third consecutive season, thereby enabling them to claim it outright. The passage through the cup was quite straightforward resulting in a 2–0 victory in the final against Lymington.

At the end of the season, the club had a balance of £50 thus making it the "richest club in Hampshire". Writing in the Bournemouth Guardian, "Offside" prophesied the advent of professionalism: We shall be having some Scotchmen in the town soon. Perhaps "Captain" Carter will be taking a holiday among the Grampians this summer and coming back with a burly Highlander or two to help them to win the senior cup next year.

Such was the club's dominance in the county that for the match against Dorset, the Hampshire F.A. selected ten players from St. Mary's. After protests from Lymington, Cowes and other clubs, St. Mary's withdrew all their players from the team. This led to a change of policy by the Hampshire F.A. although St. Mary's players continued to dominate the county sides for many years.

Personnel

Following the retirement of his brother Charles following injury, Frank Bromley took over permanently as centre-forward with former Southampton Harriers player Bob Kiddle alongside him. Arthur Fry retired during the season, leaving goalkeeper Ralph Ruffell as the only remaining player from the side who played in the inaugural match on 21 November 1885.

Kit

Having played in white "tunics" with a red diagonal sash since their first match, the players kicked off the 1889–90 season in specially manufactured shirts of cherry and white quarters, with white shorts and dark blue socks. Writing some years later, F. J. Montgomery, who was a prominent committee member who also served as "umpire", claimed that the players "baulked at the expense of new shirts" and as a result he paid for them personally.

Stadium

Since its inception, the club had had no permanent home and generally played their home matches on Southampton Common, where spectators could watch for free, using the County Cricket Ground or the Antelope Ground for cup matches and more popular friendly matches. Following the demise of the Woolston Works club, the Antelope Ground was now available. The ground, which stood in St. Mary's road, between Brinton's Terrace and Clovelly Road, had initially been known as "Day's Ground" after the Hampshire cricketer Daniel Day.

The cricket club vacated the ground in 1884 to move to the County Ground, after which the Antelope Ground was used for rugby and association football matches, with the Woolston Works team renting it from 1887 until their demise in 1889. As a result, St. Mary's Football Club became joint tenants of the ground with the Trojans Rugby Club. Where there was a clash of fixtures, St. Mary's were still able to avail themselves of the County Ground, where the football club's "de facto" president, Dr. Russell Bencraft, was the cricket club's Hon. Secretary.

Hampshire Junior Cup

Having won the Junior Cup in the two previous seasons, St. Mary's were qualified to play in the Hampshire Senior Cup, but the club committee decided to play another season in the Junior Cup with the intention of winning it for the third consecutive year, thus enabling them to win the cup outright.

The club received a bye into the second round, where they easily disposed of Boscombe (now A.F.C. Bournemouth). This gave them a repeat of the previous season's semi-final against Cowes, who were defeated in a straightforward 2–1 victory in a match played in a gale-force wind. The semi-final, against Winchester Rovers was played at the County Ground in a snowstorm and match reports indicated that St. Mary's were "fortunate" to emerge with a 1–0 victory. This set up a final against Lymington who had defeated Freemantle in the semi-final.
