"The Pirates have tentatively agreed to a one-year, incentive-laden agreement with left-hander Scott Olsen, according to industry sources. The deal is contingent on Olsen passing a physical, which is expected to happen later this week.

An official announcement could come as early as Friday.

Reached by phone on Monday, Olsen's agent, Matt Sosnick, would not confirm that a deal had been reached.

Olsen became a free agent in November after being outrighted off the Nationals' roster. He went 4-8 with a 5.56 ERA in 17 games (15 starts) last season. It was Olsen's second year in Washington, who acquired the lefty from the Marlins in a November 2008 trade."
