Leading 2-1 from the first leg a fortnight ago, the Scottish Cup holders increased their overall lead when Jim McIntyre shot home from 25 yards in the 21st minute. Dessie Baker, a former Manchester United trainee, deservedly equalised six minutes before the interval and Shelbourne came desperately close to taking the tie to extra-time after the break, but Kilmarnock clung on to the 1-1 draw which took them through.
The Shelbourne defence was sliced open by Billy Findlay for McIntyre's goal, a dipping shot from the left flank which was helped into the net by the gale-force wind.
Baker's equaliser was comical. Kilmarnock's Yugoslav international goalkeeper Dragoje Lekovic failed to control a straightforward back-pass and Baker nipped in to shoot home from 20 yards.
In the second half Shelbourne's Dave Campbell saw a header cleared off the line by David Bagen and Lekovic made up for his first-half lapse by pulling off several fine saves.
Cwmbran Town were taught a harsh lesson in Romania as National Bucharest won 7-0 to accumulate an embarrassing 12-2 aggregate margin. Adrian Pigulea led the rout with a hat-trick against the Welsh side, who trailed 5-0 at half-time.
In Poland, four goals in 16 second-half minutes destroyed Glenavon's hopes of a shock, Legia Warsaw winning 4-0 for a 5-1 aggregate win. The Irish League side's manager, Nigel Best, a Belfast schoolteacher, was unable to make the trip because of work commitments, but he managed to keep in touch with events in Warsaw thanks to a satellite telephone link provided by a radio station.Reuse content
