Harlequins have extended their lead at the top of the Aviva Premiership table with a 22-19 victory over Worcester Warriors at Twickenham Stoop.

A third-minute try from David Lemi gave Worcester an early lead before an Andy Goode penalty made it 8-0.

Goode then scored another three penalties while Quins' Nick Evans kicked over twice, as the visitors led 14-6.

However, a Matt Hooper try and another Evans penalty in the final four minutes of the first half gave the home side a 16-14 advantage at the break.

Evans kicked his fourth penalty of the night with an hour played to put Quins further ahead.

The scores were tied at 19-19 with just over 10 minutes to go when Errie Claassens came off the bench to touch down, but Evans landed a drop goal in the 74th minute to give Quins the win.
