SYDNEY -- Dodgers manager Don Mattingly said he expects Adrian Gonzalez to be in the starting lineup in Saturday night's season opener against the D-backs despite the tight lower back that forced his removal from Thursday night's exhibition game.

"For sure. No doubt about it," said Gonzalez, who took himself out of Thursday's game with a tight lower back.

Gonzalez spent Friday receiving treatment and did not take any swings or participate in the club's short workout at Sydney Cricket Ground.

"Adrian is good," Mattingly said Friday. "He won't hit today on the field. We're expecting him to go tomorrow. He won't be out [on the field] today. It's a pretty light day anyway. He hit in the cage. He feels all right. … He feels something there ... he's not 100 percent."

Gonzalez said he thought extensive sightseeing walking led to his stiff back and also believed he would be fine by Saturday night.

Mattingly has Gonzalez batting fourth in Saturday night's lineup.
