Cardiff Blues kept up the pressure on the Celtic League leaders with a solid win over bottom side Connacht.
Blues: (9) 30:
Tries: Stcherbina 2, G Jenkins.
Cons: Macleod 3.
Pens: Macleod 3.
Connacht: (12) 12:
Pens: McHugh 4.
Australian centre Marc Stcherbina led the way with two tries, while Gethin Jenkins also crossed and Nick Macleod kicked 15 points in a fine display.
Connacht led 12-9 at half-time as Mark McHugh punished any Welsh indiscipline with four penalty kicks.
But the Blues took control after the break, although they could not find a fourth try for a precious bonus point.
A scrappy first half turned into a personal kicking duel between Connacht fly-half McHugh and opposite number Macleod.
McHugh was on target with all four of his kicks, while Macleod also enjoyed a 100% record with three attempts as Cardiff Blues trailed 9-12 at half-time.
Macleod was a late swap for Nick Robinson, who picked up a small niggle before kick-off but was introduced from the bench early in the second half
Any first-half highlights came from Blues scrum-half Mike Phillips, who made several fine breaks that ultimately faded through a lack of support.
Things improved for the Welsh side soon after the break, when Macleod broke through to send Stcherbina over the try line.
Macleod continued his kicking success with the conversion, then added another two points on 62 minutes after Gethin Jenkins scored in the left corner.
By that time Robinson had arrived on the field, Macleod shifting to full-back, and it was his flat and fast passing that created the space for prop Jenkins to go over.
Connacht's struggles became worse on 70 minutes when Tom Tierney was sin-binned for cynically killing the ball in front of his own posts.
Blues wasted no time in making the extra man count, as Macleod and Chris Czekaj combined to send Stcherbina over for his second try, again converted by Macleod.
But the lacklustre handling that had already marred this game denied the Blues the fourth try that would have earned a bonus point.
Whether that lost point will come back to haunt the Cardiff side in the final standings remains to be seen.
But one consolation is that the Blues have now secured a spot in the Heineken Cup for next season.
Cardiff Blues coach Dai Young:
"We've got to be pleased with the win, but I suppose it's a measure of how far we've come that we're disappointed we didn't get a bonus point.
"We were messy on occasions, we weren't as accurate as we've been in the past, but we've got the win and we're still in with a shout of the title.
"We've got a huge game next week and we'll have to pick our performance up quite a bit to go to Ulster and win."
