Wasps went top of the Premiership with a hard-fought win against London Irish.
Wasps took an early lead through three penalties by Alex King before Topsy Ojo crossed for the first try of the game.
Riki Flutey's drop goal trimmed the gap to one point but the hosts extended their lead when Josh Lewsey went over to make it 14-8 at the break.
Two Flutey penalties to one from King saw the Exiles trim the gap to three points before Jeremy Staunton's penalty and drop goal sealed victory for Wasps.
The last time these two teams met at Adams Park, back in April last season, they produced 14 tries between them as London Irish secured a stunning 56-37 victory.
But there was to be no repeat on Friday as they combined to produce a poor spectacle despite the fine conditions.
Both sides were forced into late changes with key playmakers Dave Walder and Mike Catt both dropping out on the morning of the game.
Wasps' early dominance at the scum helped King kick them into a 9-0 lead before Flutey picked out Ojo in space on the right wing with a perfect cross-field kick.
Flutey slotted a well-struck drop-goal from 35 yards to bring London Irish back to within a point but it lasted barely two minutes before Lewsey, playing on the left wing, produced a touch of class.
The England international gathered a bouncing ball, chipped expertly around Armitage and beat the full-back to score in the corner.
From then on it was down to the boot and Staunton ensured victory for Wasps as they made it two wins out of two.
Wasps coach Shaun Edwards:
"Last Saturday against Saracens and the last half hour tonight was a Wasps performance we couldn't put in last year, where we just squeeze the life out of the opposition.
"At times last year, particularly in the Heineken Cup, we'd have probably done something silly and tried to run it.
"If we are going to win trophies we can't be one dimensional. We can't be razzle-dazzle or just tight."
London Irish boss Brian Smith:
"We were pleased with our performance.
"Our line-out was very effective and we made enough line-breaks to win the game.
"But it was a step up in performance and if we continue like that we should get our fair share of wins."
