MEMPHIS, Tenn. — The Lakers looked like they might be in big trouble in the first half tonight, but they rallied from an early nine-point deficit and led by as many as seven. Kobe Bryant and Pau Gasol scored 10 points apiece and Andrew Bynum had nine. The key was keeping the Grizzlies from gaining momentum after they started quickly. The Lakers couldn’t contain Sam Young, however. He had a team-leading 14 points on 6-for-12 shooting. The Lakers had five turnovers in the opening half, one more than they had for the entire game Saturday against the New Orleans Hornets.
