Gloucester maintained their perfect record in the Premiership Rugby Cup with another big victory as they beat Exeter 45-19 at Kingsholm.

Elsewhere, Leicester got their second win from two games with an emphatic 55-7 victory at Wasps.

Worcester began their campaign with an equally impressive win as they beat 14-man Bristol 68-13 at Sixways.

Alex Morgan went over twice in the first half as Gloucester sealed a bonus point before the break against the Chiefs, who pulled a try back shortly before the break through Rus Tuima.

George Barton scored Gloucester's fifth try three minutes after half-time before young Exeter winger Arthur Relton and scrum-half Sam Hidalgo-Clyne restored some respectability to the scoreline.

But replacement Jack Reeves got a sixth try for the hosts with three minutes to go to put them on 10 points from two games, while Exeter have yet to win a game in the competition after a bonus-point loss to Bristol last week.

At the Coventry Building Society Arena Kini Murimurivalu's first-half try for Leicester was added to by Calum Green, James Whitcombe, Hosea Saumaki and two for Guy Porter to see the Tigers lead 41-0 with 12 minutes to go.

Oliver Hartley pulled a try back with eight minutes left before Saumaki scored two more for Leicester in the final three minutes of the game.

Worcester had already scored five tries as they led 38-5 at Sixways, before Bristol had Charlie Powell sent off shortly before half-time after taking out Harri Doel in the air.

They scored five more after the break as Gareth Simpson and Tom Howe both scored twice, Billy Searle landing nine conversions to add to a try of his own.
