BRADENTON, Fla. — The Pittsburgh Pirates removed former starting right fielder Brandon Moss from their 40-man roster Monday and now have 10 days to trade, release or waive him.

Moss, a former Red Sox prospect acquired in the Jason Bay trade in July 2008, hit .081 this spring while apparently losing a spare outfielder's job to John Raynor.

Moss hit .232 with 13 home runs and 64 RBI in 178 games with Pittsburgh.

Moss was replaced on the 40-man roster by right-hander Hayden Penn, who was claimed on waivers from the Florida Marlins. Penn was 1-0 with a 7.77 ERA in 16 games with Florida last season and is 4-6 in 30 games with the Orioles and Marlins.
