Saracens 7-3 Harlequins
Saracens are on the charge again.

That is, until they get two metres away and somehow Quins get a turnover and hoof it clear.
Exeter 31-34 Bristol
With 10 minutes remaining at Sandy Park, Bristol's Gavin Henson lines up a penalty from 52 metres.
He tees it up, stands, composes himself... and it falls shot!
Still, bottom side Bristol still lead the high-flying hosts.
Saracens 7-3 Harlequins
Image source, Rex FeaturesA set piece move from Saracens eventually finds Alex Goode out wide and the Saracens full-back puts in a grubber kick for Chris Ashton to chase.
As the ball bounces up, Mike Brown is unable to gather it with Ashton right next to him and it bounces kindly for the Sarries wing to dot down.
Owen Farrell, as you'd expect, slots his conversion.
Saracens 5-3 Harlequins

Saracens 0-0 Harlequins

Bristol's maul defence simply could not stop that man!
