Hawick were the only other Borders team to join Kelso in the last eight of the BT Scottish Cup last weekend, following exits for fellow Premiership sides Gala and Melrose.
The Green Machine vanquished all memories of their poor showing at Raeburn Place in the league just a few months ago, to run out 35-27 winners with a much more positive performance.
Hawick held a narrow 20-17 lead at the break with tries coming from player/coach Nikki Walker, Shawn Muir and John Coutts, with Mattie Douglas adding a penalty goal and a conversion.
With their back line looking increasingly effective, Hawick turned it up a notch after the restart with further touch downs coming from Coutts and Neil Renwick who also added a penalty with Douglas slotting another conversion.
Across at Old Anniesland Melrose were grounded by Glasgow Hawks. Despite trailing for most of the first period before levelling the scores at half-time (7-7), the hosts dug deep and won 19-12. Blair Hutchison and Damien Hoyland were the Melrose try scorers, with Joe Helps adding one conversion.
Gala slumped to probably their worst defeat of the season at home to Stirling County. Keith Young’s first half try was their only score of the game as County ran riot in the second period, putting on 30 points without reply to win 40-5, heaping more pressure on the Maroons, who appeared to have forgotten the art of tackling.
In the Border Shield, St Boswells retained their remarkable 30+ unbeaten record with a 17-7 win at home to Berwick, from a league above them, while Hawick Harlequins saw off the challenge of Earlston at the Haugh by 46-21.
