Red Sox general manager Ben Cherington said after the World Series that it was unrealistic to expect the roster to remain intact. Change, even for championship teams, can be beneficial.
That process started Tuesday when the Sox agreed with veteran catcher A.J. Pierzynski on a one-year contract worth $8.25 million. Pierzynski will replace Jarrod Saltalamacchia as the primary catcher.
The Red Sox were interested in retaining Saltalamacchia, but only for a deal of no more than two years. When negotiations broke down, they turned to Pierzynski.
Cherington deferred comment until after Pierzynski has his physical in Boston, which will be this week.
Saltalamacchia did not lack options and later Tuesday agreed on a three-year, $21 million deal with the Miami Marlins. Full story for BostonGlobe.com subscribers.
