Girvan won 2-0 on Saturday with goals from Darren Mitchell on 40 mins and Marc Dyer on 80 mins.
Dalry went down to 10 men after 20 minutes after an off the ball incident and straight red. Scrappy game overall, but Girvan dominated throughout.
Guirvan are now up to seventh in the league and play Ashfield on Saturday in the Scottish Junior Cup.
For Girvan it is a tough tie as they lost to Ashfield in the West of Scotland cup a few weeks ago.
