The &lt;a href="2002%E2%80%9303%20snooker%20season"&gt;2002/2003 season&lt;/a&gt; saw Hann begin as a player who was ranked 14th in the world. He was unable to win a match in the season's first four ranking tournaments. Hann's top sixteen world ranking allowed him to enter the non-ranking Masters tournament for the first time in his professional career, losing in the first round 4–6 to Lee. This marked a turning point in his season as he reached the second round of the next two competitions and the quarter-finals of the 2003 Irish Masters. At the World Snooker Championship, Hann defeated Parrott 10–5 in the first round, before he was defeated by Mark Williams 13–2 in the second round.
