Campbell lost in the first round to local favourites in the first two ranking events he qualified for in the 2013–14 season. In the Australian Goldfields Open it was Neil Robertson who eliminated him 5–1 and at the Indian Open he lost 4–1 to Pankaj Advani.&lt;ref name="2013/14"&gt;&lt;/ref&gt; At the UK Championship Campbell saw off Lü Haotian and Michael White, but was then beaten 6–2 by Ronnie O'Sullivan. Campbell could not advance beyond the first round in any of the remaining ranking events and suffered a surprise 10–4 defeat to Alex Borg in World Championship qualifying, a player who had until then only won three matches all season.
