CHICAGO (Reuters) - The Chicago Bulls slumped to their worst shooting performance of the season as the visiting Toronto Raptors cruised to a 110-78 victory on Saturday.

Chris Bosh scored 25 points and had 12 rebounds for the Raptors, who jumped out to a 37-16 first quarter lead to set the tone of the game. Toronto have now won two in a row after a five-game losing streak.

Guard Marco Belinelli added 15 points for Toronto while three other Raptors scored 10 or more points. Rookie DeMar DeRozan had all 11 of his points in the first quarter, where Bosh collected 13 of his.

"I just want to get back to how I used to be playing," DeRozan said. "I was settling a lot for jump shots at the beginning of the season and just getting away from my game -- getting to the basket, getting fouled and getting to the free throw line."

John Salmons and Jannero Pargo led Chicago with 13 each. Brad Miller was the only other Bull in double figures with 11 points.

"I'm very disappointed in the approach," Bulls coach Vinny Del Negro said after his team lost for only the second time in seven home games.

"We have to play with more hunger and effort," Salmons added.

Chicago's Joakim Noah was ejected in the third quarter after receiving his second technical foul for arguing with officials. He had nine points and seven rebounds.
