From the Championship to the Premiership, into the Champions Cup and now the play-offs, Exeter are a side looking well set for a home semi-final and a shot at the title.

Olly Woodburn, Phil Dollman and Jack Nowell scored the tries on a performance that was built on foundations of incredible defence.

Rob Baxter's side up into second, two points clear of Wasps.

There won't be too many positives that Wasps can take from this game, but the expert way they have defended the Exeter driving maul is one.

They stop another one close to their own line and have the put in to the scrum.

Exeter will all the momentum and all the energy on the pitch.

Winning another penalty inside Wasps territory, they kick to touch and will aim for a fourth try of the afternoon.

With a losing bonus point out of sight for Wasps, can Exeter get a fourth try and a bonus point to nudge even further ahead?

Geoff Parling appeals for the score but the referee judges that it was held up first and there will be a five metre scrum for the Cheifs.

Well James Short and Rob Miller have 'simultaneously grounded' the ball says the television match official, much to the annoyance of the home faithful.

Exeter do now have themselves a five metre scrum though.

It looks as if James Short has nicked in ahead of Rob Miller here to score Exeter's third try...
