Andre Gray scored his first Premier League hat-trick to move Burnley nine points clear of the relegation zone and heap more misery on David Moyes with a 4-1 win over Sunderland.
Gray broke the deadlock after 30 minutes at Turf Moor, making the most of some abysmal Sunderland defending and setting the tone for another dreadful day for Moyes.
He wrapped up his hat-trick with two goals in just under three second-half minutes before Ashley Barnes' 67th-minute penalty added to Sunderland's humiliation.
Jermain Defoe did restore some pride for Sunderland four minutes later, but his effort will provide little comfort for a team that lost Lamine Kone to injury 24 minutes in and saw Victor Anichebe sustain a hamstring problem.
