May 13 (Reuters) - Swansea City moved to within sight of Premier League survival on Saturday with a comfortable 2-0 victory against a lacklustre Sunderland side already doomed to relegation.
With third-from-bottom Hull City in action 24 hours later 17th-placed Swansea moved four points clear of their rivals with goals by Fernando Llorente and Kyle Naughton.
Spaniard Llorente headed Swansea in front after nine minutes from Gylfi Sigurdsson's inch-perfect delivery.
Full back Naughton then hammered a stunning angled drive past Jordan Pickford on the stroke of halftime.
Bottom club Sunderland's resistance was feeble throughout and they proved accommodating hosts as Paul Clement's Swansea picked up a third win in their last four matches.
Swansea will be safe if Hull lose to Crystal Palace on Sunday. (Reporting by Martyn Herman; Editing by Toby Davis)
