For the second season in a row Day qualified for every ranking event. A pair of last 16 defeats at the Wuxi Classic and Shanghai Masters proved to be his best results in the first half of the year.&lt;ref name="2014/15"&gt;&lt;/ref&gt; At the Haining City Open he achieved his first official maximum break in his last 32 match against Cao Yupeng. Day would go on to reach the quarter-finals, but lost 4–2 to Oliver Lines. After Day won the final two frames of his first round match against world number one Ding Junhui at the German Masters to eliminate him 5–4, he said that he was working on his consistency to get back into the highest echelons of the game. He then beat Alfie Burden 5–2 to face Liang Wenbo in Day's only quarter-final appearance of the season and was narrowly beaten 5–4.
