Biggar 27 Aberdeen Grammar 19
Aberdeen Grammar suffered a first-half collapse which cost the Rubislaw side the opportunity to move away from the National League 1 relegation area at the expense of fellow strugglers Biggar, who did just enough to earn a 27-19 win.
Grammar coach Stuart Corsar's patience with his side is reaching breaking point.
He said: "It's just not good enough. We simply fell to bits in a 10-minute spell in which once again our discipline let us down.
"We leaked two tries thanks to silly mistakes. Failure to do the basics right cost us, though once we put that behind us we did enough to win the game in the second half. There again, we have said the same thing after a number of games this season."
Playing into a strong wind, Grammar played neat, organised rugby in which number eight Chris Jollands was a key figure, scoring the first of his brace of tries to give the home side something to think about in the difficult conditions, especially as the reliable Alex Hagart kicked the conversion.
Grammar then proceeded to shoot themselves in the foot, conceding two sloppy tries in the space of 10 minutes, giving the homesters a platform on which to build.
They did so through a further converted try and penalty before half-time to lead 24-7.
Home centre Graeme Hunter was particularly impressive, kicking three conversions and a penalty in a half largely dominated by the Biggar pack.
The second half was a different matter as Hagart pinned back the Borderers with his accurate kicking, while the drive tactics of Jollands proved very effective.
The appearance of Ross Lumsden from the replacement bench gave Grammar the edge, enabling full back Alex Ratcliffe the opportunity to dart over for an unconverted try, followed by a second from the irrepressible Jollands, which was converted by Hagart.
Biggar finally shut the door on Grammar, denying the Rubislaw side even a losing bonus point when Hunter kicked a penalty.
Grammar's home game against bottom Hillhead Jordanhill now becomes a must-win game.
"We need to set new targets and start being more consistent," said Corsar.
