The four semi-finalists in the Singles Knockout of the Industrial Electrical Services Sudbury and District Bar Billiards League are now known after the final rounds were completed at The Saracens and Cornard Five Bells.
In the first quarter-final at The Saracens, an all-Five Bells clash saw Dean Walton secure a last-ball 200 at his third attempt to beat Malcolm Groome 880-810.
Luke Cole-Watts (Mauldons Adders) beat Colin Norledge (The Bay Horse A) and, in what looked like the tie of the round, Chip Millins (The Saracens) made home table advantage pay as he saw off Alasdair Carnegie (The Bay Horse A) 986-660.
In the final game of the round, Dennis Watts (Mauldons Adders) overcame Charlie Townsend (Hadleigh Eight Bells) in a round where the scores did not reach any peaks.
Cole-Watts eased into the semi-finals, accounting for Walton, and he will now meet his father, who beat Millins after the latter lost a good break by completely missing the ball.
Higher scores were being recorded at Cornard Five Bells, where Steve Hale (The Bay Horse A) knocked out Doedy Munson (Edwardstone Wild Horses), racking up an impressive 2070 that included an 800-plus break.
Another Wild Horse player had better luck as Melvyn Willis edged out Chris Cass (Mauldons Adders) 1010-650.
Bob Hedley (Cornard Five Bells) withheld a late challenge by Del Atton (Brewery Tap), but fellow Brewery Tap star Dave Lillie gained a cautious win against Melvin Tilbury (Hadleigh Eight Bells).
Hale continued his earlier good form to narrowly beat Willis 1090-960 and, in another close contest, Lillie beat Hedley 1260-1160 so the two victors will now do battle on finals night.
The Knockout Cup final between Mauldon Adders and The Saracens takes place at The Thatchers Arms tonight (8.30pm).
A good and well-supported contest is anticipated.
