Former England fly-half Charlie Hodgson kicked a magnificent seven penalties from seven attempts in a 29-24 win over Wasps but it was not quite enough to enable Saracens to depose Harlequins at the top of the Aviva Premiership.
Hodgson's only kicking miss was a conversion attempt from the touchline after lock Alistair Hargreaves scored Sarries' only try.
South African Hargreaves had an afternoon of mixed fortunes, grabbing his charge-down try and being sin-binned before being carried off on a stretcher following a controversial challenge by James Haskell.
Saracens' other three points came from a Nils Mordt penalty while Hodgson was off the pitch receiving treatment for a cut.
But Wasps pushed them all the way, with tries from winger Tom Varndell and scrum-half Charlie Davies, three penalties and a drop goal from Nick Robinson and a conversion by his replacement Tommy Bell not quite enough to stop their four-match winning run in all competitions from coming to an end.
