GLENDALE, Ariz. -- Dodgers starter Paul Maholm lasted only 2 2/3 innings, allowing home runs by Todd Frazier and Chris Heisey among his six hits, as the Reds rolled to an 8-2 victory on Thursday at Camelback Ranch.
Reds starter Alfredo Simon allowed one run on five hits over 4 1/3 innings with three strikeouts.
An error by shortstop Hanley Ramirez paved the way for a four-run third inning against Maholm.
"You're going to have days like this. I've had worse," said Maholm, the backup to Josh Beckett as the fifth starter. "For me, what's important is to be healthy and get my mechanics where they need to be and go from there."
In addition to the solo homer by Frazier and the three-run shot by Heisey, Maholm allowed a double to Ramon Santiago, who later had a second hit.
The Dodgers scored in the fourth inning on singles by Juan Uribe, Andre Ethier and Scott Van Slyke before Justin Turner's sacrifice fly. Ramirez homered off Lee Hyde in the fifth inning, clearing the left-field grass berm.
Up next: The Dodgers make their first trip to new Cubs Park on Friday to face the North Siders at 1:05 p.m. PT. The game can be seen live on MLB.TV.
Beckett said he plans to make the start against the Cubs despite a sprained right thumb. The right-hander was hit by an opening clubhouse door about 10 days ago. Up to that point, Beckett was having a healthy recovery from last year's thoracic outlet syndrome surgery.
