David Strettle scored on his 100th appearance for Saracens as they moved to the top of the table with a 23-10 victory over Bath.
First-half tries from Chris Wyles and Strettle, as well as a fabulous kicking performance from Alex Goode, was enough for a comfortable win.
Defeat for Bath means that their place in the top four is not yet secure, as they failed to trouble Sarries enough to threaten an upset.
Bath started slowly, struggling at times to deal with the power that Saracens possessed, but rallied to take the lead through the boot of the impressive George Ford.
Goode was on hand to level though, showing that whatever his fellow compatriot could do, he could do just as well. The game finally came to life ten minutes before the interval. Joel Tomkins' impressive offload was juggled by Chris Wyles, who eventually got control of the ball for the first try of the contest.
That score rattled Bath, who were unable to prevent a second for Mark McCall's men just a few minutes later.
Matt Banahan failed to fall on the ball in his own 22, presenting the ball to Brad Barritt, who sent through a sensational grubber kick to Strettle, who raced over the line to give his side a 17-3 half time lead.
Goode's drop goal finally stretched the visitors' lead to 17, with Bath running out of time to launch a comeback.
Saracens were holding on with 14 men after Jacques Burger was sent to the bin. With nine minutes left on the clock, the pressure finally told as the referee awarded a penalty try.
Ford's conversion gave the home side hope, though that hope looked all but gone moments later.
Goode kept his nerve to send over a penalty, meaning Northampton will have to find a win over Gloucester on Saturday to move back to the summit.
