Marco Fu compiled the highest break of the tournament, scoring a 141 in his semi-final match against O'Sullivan.
Wenbo had made his debut in the competition the previous year, losing 4–6 to John Higgins in the first round.
This time he fought back from 2–4 behind, to lead 5–4, and required the final black ball in frame 10 to win the match, but he missed the shot, allowing O'Sullivan to tie 5–5.
[12] The 2012 Masters champion Neil Robertson (8) played Ali Carter (13), with the winner to face O'Sullivan in the quarter-finals.
[13] Two-time champion John Higgins (4) played Mark Allen (10), with the victor meeting Fu in the second-round.
Higgins, who last won the title in 2006, had been eliminated in the first round on twelve occasions prior to this year's tournament.
In the ninth frame, Allen lost a 67-point advantage by missing a blue into the middle pocket, allowing Higgins to build a break of 67 thus forcing a re-spotted black.
Allen potted the black from a long-range shot to take a 5–4 lead, but a 77 break from Higgins in the next frame drew them level at five all.
Both players missed shots in the final frame, until Allen compiled a break of 44 to eventually win the match 6–5.
Despite being the lower seed, Perry inflicted a 6–1 defeat on Bingham,[16] who had become a father for the second time two days before the match.

Despite gaining an advantage in the last frame, Williams experienced a kick on the blue ball, allowing Selby to make an 89 clearance to win the match 6–5.
[22] Pundit John Parrott later expressed sympathy for Williams, and commented that a kick "is a horrible way to lose" a match.
