Galwegians edged their Connacht rivals Buccaneers 20-17 at Crowley Park.
Buoyed by last weekend's historic defeat of Constitution in Cork, Bernie Kelly's young 'Wegians side were boosted by fit-again Connacht back David Slemen and he kicked two conversion and two penalties inside a lightning first 43 minutes for the home side.
Slemen booted an early penalty, added the extras to John Cleary's try and a 26th-minute penalty try as they stunned Buccs for a 17-0 half-time lead.
Slemen tagged on another kick three minutes after the restart, but that was as good as it got for Kelly's charges.
Buccs full-back Justin Meagher - facing off against his brother Stewart in 'Wegians colours - kicked the visitors' first points before Niall Smullen ran in behind the posts on 49 minutes for a try, converted by Meagher.
Second row Rory McCann also barged over for the Pirates on 67 minutes, for Meagher to convert but the Buccs kicker missed a late chance to draw up the game as his injury time penalty hit a 'Wegians upright.
Buccs did, at least, earn a bonus point, though.
