Marlins being cautious with ailing Ceda

Shoulder aggravation, conditioning struggles sideline righty

JUPITER, Fla. -- Playing it safe, the Marlins are shutting down right-hander Jose Ceda for a few days.

The 22-year-old reliever threw a bullpen session on Saturday, but he was held back from throwing on Sunday and Monday.

Manager Fredi Gonzalez said after workouts on Tuesday that the team isn't taking any chances.

"We're going to slow him down and give him three or four days off," Gonzalez said.

Ceda's right shoulder felt some aggravation. One of the biggest players in camp, the 6-foot-4, 275-pounder has struggled in conditioning drills such as running.

A native of the Dominican Republic, Ceda is a highly regarded prospect who projects to be a factor in the bullpen sometime this season, if not on Opening Day.

The Marlins obtained Ceda from the Cubs for Kevin Gregg, who was Florida's closer the past two seasons.

Ceda posted strong numbers last year in Double-A, going 2-1 with a 2.08 ERA in 22 appearances for Tennessee. In 30 1/3 innings, he struck out 42 while walking 14.

Ceda opened 2008 at Class A Daytona, where he was 2-2 with a 4.80 ERA in 15 games, 12 of them starts.
