Glamorgan defeated Northants by an innings and 143 runs after a superb fast bowling display from Marchant de Lange (3-61) and Michael Hogan (4-32).
Northants collapsed from 146/3 to 195 all out as Hogan and de Lange, with support from Labuschagne put the icing on the cake for Glamorgan.
"It's nice to be on the other side of results like that because we had a few games last season when we were on the losing side," said captain David Lloyd. "The lads know how to win games at the moment and to grind out results like (the draw with) Sussex last week when we could quite easily have folded.
"We're not thinking that far ahead (about a promotion bid), we're keeping to our plans and disciplines, but when it comes to that point of the season, hopefully we'll be there or thereabouts. If we stick to what we're doing, there's no reason why not."
Tom Cullen scored a career best 63 and took seven catches in the match to help propel Glamorgan towards success.
"Hogan and de Lange are the spearheads of our attack, and to see them come out after lunch with a relatively old ball on what was still a good batting wicket and to blow them away like that was awesome, a great sign of things to come.
"I just want to keep contributing to wins like this, we work hard on our catching as a team and hopefully we can just keep going from here."
