Debutant Ted Hill's last-minute try snatched a dramatic 44-37 Premiership win for Worcester Warriors after Leicester Tigers came roaring back, while Saracens went top with a bonus-point win over Gloucester.

Worcester claimed their first success of the season to climb off the bottom of the table at Welford Road on Sunday, but Leicester produced an almighty second-half fightback to leave a pulsating contest in the balance in the closing stages.

An early Duncan Weir double got the Warriors off to a flyer and they were 30-11 up at half-time following scores from Jack Singleton and Chris Pennell.

The Tigers were a different animal after the break, Jonny May, David Denton and Sione Kalamafoni crossing before George Ford converted his own try to make it 37-37 five minutes from time.

Worcester were not to be denied, though, 19-year-old lock Hill marking a bow to remember by diving over in the left corner and Weir taking his time before adding the extras to take his tally to 22 points on a painful afternoon for Leicester.

Champions Sarries were too strong for Gloucester at Allianz Park as Richard Wigglesworth celebrated making a record 266th Premiership appearance with a 38-15 drubbing.

There was a first-half double for Maro Itoje after David Strettle crossed, then Sean Maitland and Alex Lozowski went over as Danny Cipriani failed to make his mark following his omission from an England training camp.
