LAKE BUENA VISTA, Fla. -- The Pittsburgh Pirates have reached agreement with free-agent left-hander Scott Olsen on a one-year contract, a baseball source told ESPN.com. Olsen will earn a base salary of about $500,000, and could make an additional $3 million in incentives based on starts.
The deal includes a 2012 club option for about $4 million, the source said.
Pittsburgh general manager Neal Huntington is trying to upgrade a starting rotation that went 34-84 with a major league-worst 5.28 ERA last season.
Olsen, who underwent shoulder surgery in 2009, posted a 5.56 ERA in 81 innings with Washington in 2010. He has a career 37-49 record with a 4.85 ERA in six seasons with the Florida Marlins and the Nationals.
