Mursley United sent Winslow United crashing out of the Berks and Bucks Intermediate Cup with a 3-1 win on penalties.
The match finished level at 1-1 after extra-time but it was the SSML Division Two side who triumphed over their higher-ranked counterparts.
Jellani Blair came in for Pat Crouch for Mursley as the visitors matched their SSML Division One opponents in the early exchanges – although Drew Mitten had the ball in the net for Winslow only to see the flag up for offside.
Chances were few and far between in an even first half and the two sides went in level at the break with all to play for.
The game sparked into life in the second half, with Mursley taking a shock lead six minutes after the break. A Kevin Goodluck free-kick from the halfway line was met by Ben Brill, whose looping header cleared Boateng in the Winslow goal and dropped into the net.
Winslow replied immediately, however, as a Hateley Mercer cross flicked off the head of Robin Tucker, eluding Dean Trowbridge in the visitors’ goal and Liam Gallagher had the easy task of nodding into an empty net.
This galvanised the hosts and Vinnie Shrieves drew a good save from Trowbridge from a free-kick before he rose above the defence to head against the post as Mursley hung on and were relieved to hear the final whistle.
Jakub Kaszpryck created the only real chance in extra-time, as he drove through and shot from the edge of the area, but straight at Trowbridge.
That meant penalties with Mursley to take first – Jed Chapman driving his effort high into the net beyond Boateng. Trowbridge was then the hero as he saved penalties from Shrieves and Mitten before Alex Collard and Jack Westbrook put Mursley in control and Trowbridge secured their place in the second round when he saved from Bobby Macdonald to end a thrilling tie.
