Exeter Chiefs left the Ricoh Arena with all five points following a thrilling encounter with Wasps, winning 41-27.
Rob Baxter's men blew away their opposition in the first half with four tries: two from Thomas Waldrom – who finished with a deserved hat-trick – and one a piece from Jack Nowell and Mitch Lees, with Gareth Steenson kicking seven points.
Wasps only points came from two Jimmy Gopperth penalties and a single try from Frank Halai. Wasps were far more effective in the second half, scoring two tries through Ashley Johnson and Lorenzo Cittadini.
But, Exeter sealed the win with two tries of their own. Waldrom scoring his third of the night and Moray Low powering over.
On a blustery evening at the Ricoh, it was the Chiefs who opened the scoring with three points from the boot of Steenson. Despite Wasps impressive start to the season, Exeter were the first to cross the whitewash in Coventry.
Waldrom, who was the Premierships' top try scorer last season, went over the line after a powerful drive from the Chiefs pack. After 20 minutes, Wasps finally got on the scoreboard with a penalty from Gopperth.
Despite a sustained period of pressure from the side, Exeter scored their second try of the game through Nowell, but the try was contested by Wasps after they believed Gaskell was blocked from making the tackle.
Gopperth added another three points from the tee to keep his side in the half after the Chiefs were penalised for not rolling away. Exeter's rolling maul caused havoc in the Wasps defence and the away side had the bonus point secured before half time through a a try from Lees and a second from Waldrom.
Halai closed the deficit for Wasps with a try just before the break. Wasps began the second half as they finished the first, with Johnson crashing over from close range.
The Wasps' momentum continued to build when they scored their third try through Cittadini to level the scores.
The Chiefs' driving maul crossed the line again to kill the Wasps momentum, with Waldrom sealing his hat-trick. After a dry period for both sides, Exeter crossed the line for the sixth time in the game through replacement tighthead Low to secure an impressive 5 point win for the away side.
However, an entertaining encounter was marred by a serious looking injury for Exeter golden boy and England starlet Henry Slade.
