Saracens have reached the Aviva Premiership playoffs with a 68-17 victory over relegated London Welsh.

England number eight Billy Vunipola gave his side a dream start as he powered over the line following a driving maul.

However, London Welsh hit back through centre Nic Reynolds, who touched the ball down after a neat sideways pass from Tom May.

Saracens dominated general play and added two more tries through winger David Strettle and prop Mako Vunipola, but the hosts stayed in it thanks to Chris Elder's try.

However, the visitors pulled away as Chris Ashton bundled the ball down for their fourth try before the break, which confirmed a crucial bonus point, and Alex Goode wrapped the game up with a fine solo effort just three minutes after half time.

Juan Figallo added a sixth try after a quick penalty from close range, before some intelligent interplay from Owen Farrell and Goode helped to release Ashton, who scored his second try of the match.

The former England winger completed his hat-trick just four minutes later after some good work from Goode, before he added his fourth of the afternoon with a simple run under the posts.

Charlie Hodgson completed the rout with a try in the 77th minute as Welsh ended the season without a win.
