SEVILLA, Spain, Dec 6 (Reuters) - Ferran Torres scored a first-half hat-trick as Barcelona won 5-3 at Real Betis in LaLiga on Saturday, bouncing back after conceding an early goal to extend their lead over Real Madrid at the summit to four points.

Antony marked his return from suspension by scoring from Betis' first attack in the sixth minute, with Jules Kounde playing the winger onside as he rifled the ball into the net.
