The Lakers’ big goals going into tonight’s glorified exhibition against the Sacramento Kings at Staples Center were to avoid injuries and get a victory. They looked good one one count, and not so good on the other. They had a modest lead at halftime, but lost Jordan Farmar to a strained left hamstring. Farmar won’t play in Wednesday’s regular-season finale against the Clippers, a team spokesman said. Meanwhile, Pau Gasol scored 13 points and grabbed six rebounds to lead the Lakers. Shannon Brown added 12 points on 5-for-10 shooting. Kobe Bryant did not play in order to rest several nagging injuries. He also won’t play against the Clippers. Jason Thompson led the Kings with 15 points.
