PITTSBURGH, Jan. 2 (UPI) -- The Pittsburgh Pirates on Wednesday agreed to terms on a two-year contract with former closer and free agent Mike Williams, who saved 22 games for the team last season before being traded to the Houston Astros.
Financial terms for the deal, which also includes a club option for a third season, were not disclosed.
Despite his success for the Pirates last year, Williams, 33, was dealt to the Astros at the trade deadline for righthander Tony McKnight, Houston's No. 1 pick in the 1995 draft.
In 40 appearances for Pittsburgh last year, Williams was 2-4 with a 3.67 ERA. The righthander appeared in 25 games as a setup man for the Astros, going 4-0 with a 4.03 ERA.
Mike Fetters served as the Pirates' closer after Williams was traded, but recorded just nine saves.
In four seasons with Pittsburgh, Williams was 12-14 with a 3.59 ERA in 207 appearances. He assumed the closer role in 1999 and converted 69-of-81 save opportunities over the next three seasons.
McKnight made 15 starts for the Pirates last season after being acquired from the Astros, posting a 3-6 record with a 4.95 ERA.
