8:00pm: Berkman's extension includes a full no-trade clause, tweets Joe Strauss of the St. Louis Post-Dispatch.

10:43am: Headed for a potentially turbulent winter, the Cardinals made the rest of their offseason that much simpler today, agreeing to a one-year, $12MM extension with Lance Berkman. The sides had been discussing a possible deal this month, though talks had appeared to lose momentum.

The Cardinals have announced the deal (Twitter link) and Derrick Goold of the St. Louis Post-Dispatch added (on Twitter) the value of the deal and that no money is deferred. MLBTR's Tim Dierkes suggested on Tuesday that a $12MM deal would be a fair compromise.

Berkman, 35, has enjoyed a resurgent season in St. Louis, hitting 31 homers and posting a .300/.412/.555 line through 558 plate appearances. The switch-hitter has played first base and both corner outfield positions for the Cardinals this year. He leads the league with an OPS+ of 169 and has added 4.6 wins above replacement, according to FanGraphs.

The Cardinals, who are gaining ground in the National League Wild Card race, also extended Chris Carpenter this month. They have signed five players to extensions during the month of September since GM John Mozeliak took over. Only one other MLB team has extended a player during the final month of the regular season in that time (Tim Byrdak of the Mets signed an extension this month).

Albert Pujols, Edwin Jackson and Rafael Furcal are among the Cardinals who will file for free agency after the season. Moye Sports Associates represents Berkman, as our Agency Database shows.
