The opening day’s play in the Johnston Oils-sponsored West Lothian Masters saw two of the 16 seeds crash out of the £4000 event.
No.8 seed Cameron Greer of Bathgate – winner of the Green Jacket in 2012 – made a 21-19 first-round exit to Steven Fleming of Buchan Park.
Uphall Station’s Calum Black, the No.16 seed and recent District Junior Singles champion, fell at the first hurdle after a 21-16 defeat by Alan Patterson of Broxburn in 22 ends.
Frazer Muirhead, uncle of fallen No.8 seed Greer, usually enjoys good runs in the WLM but he too made an early departure this year.
Muirhead, 55, spent all last week on official duty at the national championships and may not have been sufficiently at the sharp end of match fitness to cope with Brian Clarkson of Winchburgh, who won 21-13.
Peter Lynch, 47, captured the Masters title in 2003 and, although not seeded, came into the 2016 event as the District Champion. However, the Whitburn bowler suffered a 21-14 defeat by Greg Baldry of Newbridge.
