Joe Torre will step down as Los Angeles Dodgers manager and be replaced by Don Mattingly at the end of the season, a source told ESPNLosAngeles.com’s Tony Jackson on Friday.

An announcement is supposed to come before Friday’s Dodgers game, the newspaper reported. The move was first reported by the Los Angeles Times.

Torre is 251-220 in three seasons with the Dodgers after a 12-year run with the New York Yankees in which he won four World Series titles. The Dodgers made the playoffs in each of Torre’s first two seasons but are currently in fourth in the NL West this season.

Torre has managed 29 seasons in the big leagues with the Mets, Cardinals, Braves, Yankees and Dodgers. He is in the final year of his contract with the Dodgers.

Mattingly has been the Dodgers hitting coach since 2008. He served in the same role for the Yankees from 2004-06 and was Torre’s bench coach in 2007.

Torre jumped to the Dodgers after the Yankees reportedly wanted him to take a pay cut to return to the Bronx for a 13th season.

It was not immediately clear if Torre would announce his retirement, was just walking away from the Dodgers or would take another role with the organization. The team has been mired in uncertainty as a result of the messy divorce case of owner Frank McCourt and his wife, former Dodgers executive Jamie McCourt.
