After being acquired from Toronto in May, Plesac made 41 appearances for Philadelphia, posting a 2-1 record with one save and a 4.70 ERA. The lefthander, who turns 41 in February, held opponents to a .190 average and on Aug. 28 became the seventh pitcher to reach 1,000 career appearances.
"At this point in my career, it's not just about playing but being a part of something special," Plesac said. "I wanted one last grasp at that feeling but following the season, I felt comfortable with retiring, although I was kind of waiting for something to grab me to get me back."
"I promised (general manager) Ed Wade and (manager) Larry Bowa that if I was going to play next year, it would be with the Phillies and when they signed Bell and Thome, it was obvious they meant business in putting a team on the field," he said. "In my heart, I feel something special is happening in Philadelphia and I want to be a part of it."
In 1,006 career games with Milwaukee, the Chicago Cubs, Pittsburgh, Toronto, Arizona and Philadelphia, Plesac has a record of 63-70 with 156 saves and a 3.67 ERA.
