The &lt;a href="2012%E2%80%9313%20snooker%20season"&gt;2012/2013 season&lt;/a&gt; was a breakthrough year for Lisowski as he qualified for five ranking tournaments, including the World Championship, and reached his second final as a professional.&lt;ref name="2012/13"&gt;&lt;/ref&gt; The first tournament he reached was the Australian Goldfields Open by beating Dave Harold and he lost 2–5 to Mark Davis in the first round in Bendigo. He couldn't qualify for the next two events, but then defeated Chen Zhe and Joe Perry to feature in the UK Championship for the first time. In his match against Chen, Lisowski made the first 147 in competitive play of his career. In the first round of the event in York, Lisowski lost 2–6 to Stuart Bingham. Lisowski beat Ian Burns and Jamie Burnett to qualify for the China Open and then saw off Zhou Yuelong to advance to the last 32. He played good friend Judd Trump and made a 131 break in 5–3 win, before coming back from 2–4 down to triumph 5–4 against Mark Davis and reach his first ranking event quarter-final. However, this time it was Lisowski who let a 4–2 lead slip as he lost 4–5 to Shaun Murphy, with Murphy stating that snooker had seen the future with Lisowski's performances during the week.
