Section A leaders West Lothian increased their prospects of clinching a place in the play-off final of the indoor bowls Premier League with a 71-66 victory over chief rivals Blantyre in a battle that went right down to the wire at the Inveralmond stadium.
Wins on the rinks skipped by Neil Speirs and team captain Thomas Mann were good enough to cover the setbacks suffered by Mark Allison and Calum Logan.
The visitors were in a match-winning position at 66-64 up going into the last ends across the carpet, but in an intense and thrilling climax, West Lothian captured the two winning points with a magnificent 7-0 clean sweep.
West Lothian led by four points and 90 shots going into an away visit to basement club Inverclyde followed by a home game against Bainfield.
Blantyre won the opening seven ends 25-21. However, West Lothian showed their resolve with a 29-21 fightback on the second end then stood their ground to edge the third phase 21-20.
Balbardie IBC, meanwhile, remain in pole position in the race to clinch the promotion play-off position in Division 1C having made it six wins out of seven by beating Teviotdale by 28 shots at Bathgate.
Wins on the rinks skipped by Ewan Shearer, Gary Orr and Sandy McDougall suppressed a Teviotdale challenge that had shown some teeth with a double-figure triumph over Jim Speirs.
The match result keeps Balbardie four points ahead of rivals Tweedbank, but with one game more played, so there remains a threat from the Borders outfit following their own 94-66 win at home to Headwell.
Tweedbank are also 41 shots adrift of Balbardie, but will be favourites to win both their remaining fixtures against the bottom two clubs, away to Berwickshire and at home to Teviotdale.
