Free-agent relief pitcher Jonathan Papelbon agreed to a four-year contract with the Philadelphia Phillies, Comcast Sportsnet reported on its CSNPhilly.com website.
The deal, which is pending a physical, approaches $50 million in value, the website said, citing multiple unnamed sources.
An e-mail seeking comment from Greg Casterioto, a spokesman for the Phillies, wasn’t immediately returned.
Papelbon, a right-hander who turns 31 on Nov. 23, has played his seven-year Major League Baseball career for the Boston Red Sox.
The four-time All-Star had 31 saves last seasons with a 2.94 earned run average, and has 219 saves and a 2.33 ERA for his career.
The Phillies had a major-league best 102-60 record last season before falling in five games to the St. Louis Cardinals in a division-series matchup.
