The Pirates on Friday signed left-hander Javier Lopez to a one-year contract.
Lopez, 32, spent the past four seasons with the Boston Red Sox organization. In that span, he pitched in 172 games for the Red Sox with a 3.30 ERA. He spent most of this past season at Triple-A Pawtucket and also played for Puerto Rico in the World Baseball Classic.
“Javier has proven to be a capable major league reliever who has the abiltiy to attack both left- and right-handed hitters,” general manager Neal Huntington said. “He will provide a solid relief option for manager John Russell in 2010.”
