MADRID, Nov 7 (Reuters) - Pedro netted twice and Thierry Henry scored his first of the season to set leaders Barcelona on their way to a 4-2 win over Real Mallorca in La Liga on Saturday that kept the champions a point clear of Real Madrid.

Second-placed Real, missing the injured Cristiano Ronaldo, held on for a 3-2 win at city rivals Atletico in the late match despite going down to 10 men in the 66th minute.

Real were cruising after Brazilians Kaka and Marcelo scored first-half goals and Gonzalo Higuain added a third on 64 minutes before Sergio Ramos was shown a straight red for a foul on Sergio Aguero.

Roared on by the home crowd, Diego Forlan pulled a goal back with 11 minutes of regular time left, Aguero added another three minutes later and Iker Casillas produced a superb save to deny the Argentina striker at the death as Real held firm.
