Our 9/1 pre-tournament outright tip John Higgins made a strong start at the Shanghai Masters as he defeated Alexander Ursenbacher 5-2.
The Scot made an impressive 131 break which put him 4-1 ahead of the promising Swiss cueman, before he sealed victory with a run of 73 and he is now into 7/1 with Sky Bet to lift the trophy.
World number one Mark Selby (4/1 favourite) got back to winning ways after last week's defeat to Luca Brecel at the Champion of Champions in Coventry by beating Ian Burns 5-2.
Selby, a winner in China just two weeks ago at the International Championship, did struggle early on and trailed 2-1 but breaks of 68, 120 and 132 got him home.
Welshman Michael White (66/1) claimed a first ever career win over Mark Davis at the 10th attempt, edging home 5-4 thanks to breaks of 76, 66 and a superb 140 - the highest of the day.
Our 25/1 each-way tip Mark Allen once more got the better of Chinese teenager Yan Bingtao as he powered to a 5-1 success.
PRICE BOOST: Ronnie O'Sullivan to win the Shanghai Masters is 5/1 from 4/1 with Sky Bet!
Less than two weeks after beating the 17-year-old 9-2 in the semi-finals of the International Championship, the Ulsterman again proved too strong with a top break of 102 and he is looking forward to doing well in China once more.
"It was a bit of a scrappy game, but I felt like I dominated," Allen told worldsnooker.com. "My safety was good and I limited him to small chances.
"I have done well in China this season despite not sleeping well - maybe that’s the secret."
Home favourite Liang Wenbo (40/1) had a top run of 125 as he saw off the stubborn Rod Lawler 5-2, while Jack Lisowski's (33/1) good recent run of form continued as breaks of 113, 117, 86, 86 and 82 saw him to a 5-1 win over Chris Totten.
