Ben Woollaston is hoping for a "life-changing" reward from the Players Tour Championship Finals in Galway after stunning former world champion Mark Williams to reach the last 16.

The 25-year-old Leicester cueman became a father in late December and would love to take home a major prize to son Edward and wife Tatiana, and to give his career a lift.

Williams looked to be in charge of their best-of-seven-frames tussle when runs of 73 and 93 helped him build a 3-1 lead, but world number 35 Woollaston came storming back and breaks of 73 and 70 saw him over the winning line.

Now he hopes to produce a run of victories, and after guaranteeing himself £5,000 by coming through one round, Woollaston can start to dream about the £100,000 winner's cheque.

Mark Selby, John Higgins and Judd Trump all fell in the first round, and although some star names survived, the opportunity for some of the lesser known names on snooker's professional tour to pocket a major prize is there.

"It would be great for me because the prize money at this tournament is good," Woollaston said.

"For me to get to the semis or final it'd be more life-changing than for the top players.

"If I don't win I hope an Alfie Burden or Kurt Maflin would do better in this tournament than the top players. I think it'd be very nice."

Reflecting on his win over Welshman Williams, who has had a tough season, Woollaston said: "I played well from 3-1 down but he played really well too, he seemed to pot every long ball and every time I came to the table I seemed to be in a difficult snooker, so I was happy to come back.

"People keep saying it's another upset but I don't see any of them as upsets, because in best-of-sevens if someone plays well they're capable of beating the top players."

Scotland's Anthony McGill kept the Saltire flying with a 4-2 victory over Englishman Robert Milkins to set up a last-16 clash with Ding Junhui.

The likes of Higgins, Stephen Maguire and Graeme Dott all bowed out in round one and 56th-ranked McGill said on "I don't know why the other Scots have gone out, they are all very good players so you would expect at least a couple of us to have a good run."

Marco Fu saw off Mark Joyce 4-2, and in the last 16 a rematch of the German Masters final awaits the man from Hong Kong, with Ali Carter blocking his route to the quarter-finals. Carter saw off Fu to land the Berlin title.
