PITTSBURGH - The Pittsburgh Pirates designated right-hander Jeff Karstens for assignment and claimed right-hander Chris Jakubauskas off waivers from Seattle.
The team made the moves on Friday.
Karstens was 4-6 with a 5.42 ERA. He was acquired from the Yankees in 2008. Jakubauskas was 6-7 with a 5.32 ERA in 35 games after unexpectedly making the majors at age 30.
The Pirates have 10 days to trade, release or send Karstens, catcher Robinzon Diaz and left-hander Justin Thomas outright to the minors.
