Saracens down Gloucester to surge into Challenge Cup semi-finals

The visitors ran in five tries, with southwest side Gloucester managing just two as they suffered a pair of yellow cards.

Saracens' Aled Davies, Maro Itoje, Jamie George, Duncan Taylor and Nick Tompkins crossed the Cherry and Whites' try-line, with England's Owen Farrell converting all five scores and also kicking three penalties.

Jack Singleton and Wales wing Louis Rees-Zammit went over for Gloucester, with their other points coming from a Billy Twelvetrees conversion and a penalty from Scotland's Adam Hastings.

Saracens will play the winners of Sunday's match between French club Toulon and London Irish in the semi-finals.

Saracens opened the scoring in just the fifth minute, when Farrell landed a straightforward penalty before Davies scored the first try after good work by South Africa prop Vincent Koch.

The hosts fell further behind when Farrell kicked a penalty after wing Ollie Thorley -- on his 100th appearance for southwest club Gloucester -- was sin-binned for a high tackle.

Gloucester got back into the contest when, with Saracens and England hooker Jamie George in the sin-bin, Singleton scored off a line-out drive.

Farrell's third penalty made it 16-5 to London club Saracens at half-time.

Hastings's penalty reduced the deficit, only for England forward Maro Itoje to force his way over off a close-range scrum for Saracens' second try.

Saracens put the result beyond doubt when Wales's Tompkins crowned a driving line-out after Gloucester prop Val Rapava-Ruskin was sin-binned for deliberately slowing down opposition ball.

George went over in similar fashion, with Farrell's kick leaving Saracens 37-8 up heading into the final quarter.

Taylor's interception gave Sarries their fifth try before Rees-Zammit's solo effort completed the scoring.
