Leaders Exeter go seven points clear with win over Saracens
Wasps go second with hard-fought win over bottom side London Irish
Leicester climb to fifth with bonus-point win at Worcester
For a moment Bath thought they might be back in the game at the Stoop as Zach Mercer crashes over.
But the decision goes to the TMO who rules that the back-row was held up.
The TMO is called upon again moments later as Bath pick and drive towards the posts but again there is no clear grounding.
Exeter 24-12 Saracens

Is that finally the moment that Saracens’ dogged spirit was broken?
Exeter’s ferocious pack were never going to let that position go after seeing the backs give away a number of chances earlier in the game.
What a vital win this will be as Exeter aim to get back on track after some poor results in recent weeks.
Penalty
And now Exeter have the perfect chance to exert their forward dominance again.
Penalty one - they opt for a new scrum.
Penalty two - warning comes from Matt Carley, another scrum is called for.
Penalty three - the referee heads for the sticks.
That surely is the decisive score with less than 10 minutes remaining.
Veainu, missed con Toomua
That injury to Luke Baldwin nullified Worcester's momentum and Leicester have gone up the other end of the field to surely complete victory.
The Tigers go through the phases before Matt Toomua clips a beautifully-weighted chip over the Warriors defence and into the arms of Telusa Veainu, who touches down.
Toomua's conversion drifts wide but Tigers now have 10 minutes to find a fourth try and a bonus point.
Exeter 17-12 Saracens
Lovely move from Exeter from a scrum with a pass inside from Henry Slade sending his side forward.
The kick goes tantalisingly towards the dead-ball area, Alex Goode mops up well but Sam Simmonds hunts him down to force a five-yard attacking scrum.
Bell
London Irish still pressing in Coventry and threaten the Wasps line once more.
The hosts hold out but are penalised and Tommy Bell nudges Irish a little closer.
Still game on in the lashing rain.
Simmonds
Exeter have had a good edge up front all day and they win another scrum penalty 30 yards from the Saracens line and fairly straight.
Joe Simmonds with the chance for the first points of the half and he measures the kick well to extend the Chiefs' lead.
Cipriani
But right from the re-start, Irish concede a penalty!
Danny Cipriani takes the lead back to more than a converted try.
Worcester 5-15 Leicester
Worcester have been putting Leicester under all sorts of pressure as they look to find a way back into this game.
But, with Warriors getting as close as one metre from the visitors' line, the Tigers stand firm and earn a breather as Chris Pennell knocks on and replacement scrum-half Luke Baldwin needs treatment for a knee injury.
Porecki, missed con Bell
Well, London Irish fighting hard and they are right back in this game.
Dave Porecki is driven over from a close-range line-out and Irish are back to within a score.

Image source, Getty ImagesWhen you think of the players Saracens are missing - the likes of the Vunipola brothers, Maro Itoje, Jamie George, Richard Wigglesworth, Owen Farrell, while Brad Barritt and Chris Wyles have come off, you have to hand it to this Saracens side.
Defensively they have been excellent, forcing Exeter to cough up numerous chances.
Can they get a chance and inflict a rare defeat on the champions at Sandy park?
Exeter 14-12 Saracens
And there you go, Saracens force a breakdown penalty on the Exeter 10-yard line.
Ben Spencer lines up the shot from outside the left post but his left boot doesn't have the legs.
Exeter 14-12 Saracens
A loose return kick gives Exeter a great chance to counter-attack.
There is space up the left channel and numbers for the hosts but a diabolical pass evades Olly Woodburn and goes straight into touch.
Exeter getting more scrappy and Saracens will be buoyed.
Bell
Finally London Irish are on the board.
They can't convert from a line-out 10 yards out but they do win a shot at goal and Tommy Bell knocks it over.
Sinckler, con Catrakilis
Image source, Getty ImagesAnd it immediately gets worse for Bath as British & Irish Lions and England prop Kyle Sinckler comes off the bench for Harlequins and rumbles over straight away.
Demetri Catrakilis adds an easy conversion and it looks a long way back for Bath from here.
Harlequins 10-5 Bath
Max Lahiff replaces Henry Thomas for Bath and within 60 seconds the prop is on his way back to the bench to put his big coat on after being sent to the sin-bin.
BBC Radio Bristol's Damian Derrick says he thinks that the yellow card is more down to Bath's indiscipline as a team rather than anything Lahiff did. The penalties have been piling up.
Exeter 14-12 Saracens
A marginal penalty for crossing is called against Saracens around half-way and Exeter kick to within 10 yards of the line.
But the maul defence is excellent and Saracens win the scrum and clear.
Still no score in the second-half.
Robson, con Cipriani
Image source, Rex FeaturesWasps win a penalty on half-way and kick to the Irish 22.
Christian Wade breaks from the line-out move and takes Wasps to the line before Dan Robson dives over.
Danny Cipriani adds the extras and now Wasps have control in Coventry.

Image source, Getty ImagesExeter have really got to start taking these chances.
Three times they have given the ball away to Saracens either knocking on or infringing at the break down.
But possession-wise and territorially Exeter are in front right now.
Exeter 14-12 Saracens
Exeter with more phases, good handling and plenty of endeavour.
But Saracens stay firm, force the choke tackle after a half-break up the right wing and they get the put in at the scrum.
