On 13 January 1999, Swansea City upset West Ham in a Third Round FA Cup Replay despite being separated by 73 places in the English football pyramid.
The two sides met at Upton Park 11 days earlier, where Swansea were denied a victory by a late West Ham equalizer three minutes from time. For the replay at Swansea's Vetch Field, the hosts were sitting in 14th place in Division Three, while West Ham were holding down the 8th position in the Premier League, three levels higher.
The Hammers created a handful of early chances, thanks in part to the return of midfielder Frank Lampard, who had missed the previous match. But they were unable to convert, with Lampard's 11th-minute header falling just inches wide of the post. Swansea keeper Roger Freestone then made a brilliant save to deny another shot from the midfielder.
Swansea nearly claimed the lead in the 21st minute when midfielder Martin Thomas beat West Ham keeper Shaka Hislop, but his shot struck the bar. Thomas was not to be denied, however, and 8 minutes later he fired a 25-yarder that curled into the bottom corner of the net. Several home supporters rushed onto the pitch, forcing a few minutes' delay while officials restored order.
West Ham pressed forward, but were repeatedly denied by Freestone as Swansea reaped a deserved 1-0 win.
