JAMES O'Connor kicked all of visiting London Irish's points as they lost 23-9 to Harlequins in the Premiership on Saturday.
The Aussie kicked over three penalties in the first 40 minutes, as the Exiles only trailed 10-9 at the break.
This was after Nick Evans had converted his own try and kicked a penalty for the home side.
After the interval, further unconverted tries from Harlequins Sam Smith and Mike Brown made sure of the victory.
Irish are next in action a week on Sunday, when they entertain Newcastle.
