TORONTO — Andrew Bynum looked a little more effective than in previous games, scoring eight points in the first half today against the undersized Toronto Raptors. Andrea Bargnani couldn’t play for Toronto because of a sore right ankle, so the Raptors were missing a 7-footer. This is Bynum’s fourth game since returning from offseason right knee surgery. He doesn’t have a lot of quickness around the basket and he’s not able to get off the floor fast enough to dunk over defenders. Toronto’s DeMar DeRozan smacked him hard as he tried a second-quarter slam. Pau Gasol led the Lakers with 10 points in the first half. Amir Johnson, a former standout at Westchester High, had 12 on 6-for-9 shooting for Toronto.
