Q: Question: Who was the head coach for the Sri Lankans team when they played against the Sussex? Passage:Threfall played for Cumberland in 1987, making a single appearance in the Minor Counties Championship against Cambridgeshire and a single appearance in the MCCA Knockout Trophy against Cheshire. In 1988, Threfall played Second XI cricket for Sussex, with him also making his first-class debut for the county in that season against Somerset at the Recreation Ground, Bath. He played regularly for the Sussex Second XI, but would only make two further first-class appearances for the county, against the touring Sri Lankans in 1990 and Cambridge University in 1991. He never batted in his three first-class appearances, but with the ball he took 7 wickets at an average of 18.57, with best figures of 3/45. He also made a single List A appearance for the county against the touring Zimbabweans in 1990. He ended Sussex's innings of 233/8 unbeaten on 17, while in the Zimbabweans innings he took figures of 3/40 from 10 overs, with Sussex winning by 95 runs. He continued to play for the Sussex Second XI until 1994.
