Mark Allen's interest in this year's World Snooker Championships is over after he was beaten 13-11 by Barry Hawkins in the second round at the Crucible Theatre.
The contest see-sawed, with Allen starting the final session 9-7 ahead and shooting a break of 81 to pull three frames clear.
Hawkins claimed the next with a run of 50 before a 113 break for Allen saw him edge closer to the finishing line.
Hawkins, who was runner up to O'Sullivan in the 2013 final, was not done, however, and he took the next five frames on the trot including a break of 102, to book his place in the quarter-finals.
Ronnie O'Sullivan fired back to take a 5-3 lead over Matthew Stevens in his second-round match.
The five-time world champion fell two frames behind his Welsh opponent in the best of 25 contest before clinching five successive frames to move into the lead.
The 39-year-old struck the first century of the match in the third, with runs of 63 and 61 putting him in front.
Stevens cut the gap to two frames at the end of the first session to leave the contest very much in the balance.
