A rock-solid defensive performance late in the game helped Wasps defeat local rivals London Irish 19-12 at the Madejski Stadium.
Head coach Dai Young was left fuming by the manner in which his side capitulated in front of their own supporters against Bath a week ago, but his charges responded well with a display full of grit and character.
The forwards will take the plaudits after a dominant display in stark contrast to their previous effort.
London Irish were determined to mark Topsy Ojo's 200th appearance with a win and end a five-match losing streak, and they started in the best possible fashion when James O'Connor kicked a second minute penalty.
O'Connor and Andy Goode traded three-pointers as defences remained on top before the Australian was yellow-carded for a deliberate knock on - an act which also saw Wasps awarded a penalty try - after a neat chip ahead by his opposite number.
Shane Geraghty pulled three points back for Irish just before the break after Wasps were penalised for crossing.
With Irish still down to 14 men Goode extended Wasps' lead shortly after the re-start with his third penalty of the afternoon.
Irish upped the tempo when restored to their full quota of players and O'Connor nailed one of two attempts at goal to close the gap to four points.
But fittingly the final act came from the outstanding Goode, who made the game safe with a drop goal.
