O'Donnell was beaten in the qualifying rounds for eight ranking events in the &lt;a href="2013%E2%80%9314%20snooker%20season"&gt;2013/2014 season&lt;/a&gt;. All 128 players on the tour entered the UK Championship and Welsh Open at the first round stage, with O'Donnell losing at this stage in both.&lt;ref name="2013/14"&gt;&lt;/ref&gt; The only event he qualified for this season was the China Open by defeating David Gilbert 5–1. He received a bye through the first round due to Stuart Bingham's withdrawal which meant he would play in the last 32 of a ranking event for the first time. O'Donnell faced Craig Steadman and was edged out 5–4. In the European Tour events his best result came at the Rotterdam Open where he beat experienced players Robert Milkins and Marcus Campbell, before losing 4–0 to Stuart Bingham in the last 16. As he ended his second season at world number 92, outside the top 64 in the rankings, his other route to remain on tour next year was through the European Order of Merit, with eight places available to non-qualified players. O'Donnell finished 59th, less than 300 points short of Tony Drago who received the final spot and entered Q School to retain his professional status. He was eliminated in the last 64 in both events and had amateur status for the coming season.
