With Matt Capps in Washington, the Pirates are looking to restock their bullpen.
Pittsburgh has engaged in talks with free-agent relievers Kevin Gregg and Octavio Dotel.
Capps agreed to a one-year, $3.5 million deal with the Nationals on Thursday morning.
Gregg made $4.2 million last season, Dotel $6 million, and each is expected to get less for 2010.
