Jimmy Gopperth kicked two second half penalties to help Wasps move to within four points of Exeter in the Premiership after a 13-7 triumph over the Chiefs.
The Midlanders played some excellent rugby on occasions but perhaps didn’t get the reward they deserved. Despite having a number of openings, they only touched down once when Marcus Watson scampered over.
Gopperth then extended their lead in the second period before Luke Cowan-Dickie gave the Chiefs hope going into the final quarter.
Ashley Johnson was also serving time off the field for a yellow card but the hosts handled it well and Gopperth secured the win from the tee.
It extended Exeter’s Premiership losing streak to three as, despite a positive opening where they put the opposition defence under pressure, Wasps deserved their win.
Dai Young’s men created a number of opportunities in the first half, but they could only take one of those when excellent hands out wide sent Watson across the whitewash.
Jonny Hill was sin-binned for a tip-tackle on Willie le Roux in the build up to that try and the West Countrymen were put under further duress.
Rob Baxter’s team almost responded through Will Chudley, when the Chiefs broke away after a turnover inside their own 22, but that was the closest they got before the break.
Wasps duly held a seven-point buffer going into the interval and they were on the front foot at the start of the final 40 minutes, but the Chiefs’ defence was much more resilient.
The departure of Danny Cipriani to injury also helped their cause and a Gopperth three-pointer was the hosts’ only reward for their pressure.
Young’s men then suffered further concerns when Watson and Alex Rieder went off injured before Johnson was sin-binned for a swinging arm into Don Armand.
With the Coventry-based outfit down to 14, Exeter benefited immediately and Cowan-Dickie set up a tense finale.
Wasps controlled matters, however, and Gopperth’s three-pointer helped them to secure the win.
