FORT LAUDERDALE, Fla. (AP) _ Charles Johnson hit a three-run homer and Ryan Minor had a solo shot as the Baltimore Orioles overcame a shaky effort by Mike Mussina to beat the Florida Marlins 7-5 Sunday.

Mussina, making his first start of the spring, allowed four earned runs and six hits in three innings and left with the Orioles trailing 5-1. Mike Lowell hit a three-run homer and Dave Berg had two hits and scored twice against the right-hander.

``I've never been the best spring training pitcher,'' Mussina said. ``I probably threw the ball over the middle too much and got one pitch up for a home run. That's the way the process goes when you start playing games in March.''

Orioles manager Mike Hargrove regarded the effort as exactly what it was: the first start of spring training for a pitcher who hadn't thrown competitively since last September.

``He hadn't pitched in forever,'' Hargrove said. ``It was just one of things that happens in an early outing.''

After Mussina left, the Marlins managed only five hits the rest of the way against five relievers. Tim Worrell won despite allowing four hits in two innings and Mike Trombley pitched a perfect ninth for the save.

Worrell and Trombley were both signed as free agents during the offseason to improve a bullpen that struggled through much of 1999. Trombley, projected to be the setup man, waved off his ninth-inning effort.

``I just happened to be the last pitcher today,'' he said.

The Orioles closed to 5-4 in the fourth against Jason Grilli. Harold Baines doubled, Will Clark walked and Johnson, a former Marlin, homered over the left-field wall.

In the fifth, Albert Belle doubled in a run off former-Oriole Ricky Bones and scored on a single by Baines to put Baltimore up 6-5. Minor homered in the seventh off Bronswell Patrick.
