Taj Gibson tied a career high with 20 points and had 13 rebounds, and the Chicago Bulls used a big first-half run to beat the Philadelphia 76ers 122-90 on Saturday night for their fourth straight victory.And this one was quite impressive. He hit 9 of 14 shots and fed off newcomer Hakim Warrick in another eye-opening performance from a rookie whose emergence made the departed Tyrus Thomas expendable.Derrick Rose scored 17 points to help the Bulls set a season high for points. So did Kirk Hinrich, who also buried three 3-pointers to give him 773 in his career and break a tie with Ben Gordon for the club record.Newcomer Hakim Warrick had a highlight reel dunk over Thaddeus Young that “got me going” and finished with 15 points. Brad Miller scored eight of his 15 during a 23-1 run to close the second half, turning a three-point deficit into a 58-39 lead and sending the Bulls to their sixth win in seven games. The Bulls set a team record for fewest turnovers with four while dishing out 26 assists.Andre Iguodala led Philadelphia with 23 points. Young scored 17 points, but the Sixers went 8:14 without a field goal during a drought that spanned the second and third quarters in their most lopsided loss this season while falling for the third time in four games.They were leading 38-35 after Iguodala hit two free throws with 5:19 left in the first half.Miller put back his own miss and led the charge as the Bulls scored 21 straight before Young hit 1 of 2 free throws with 35 seconds left.
