Jim Leyland will step down as manager of the Detroit Tigers, reports Ken Rosenthal of Fox Sports. The team will hold a press conference at 11:30 a.m. ET to announce the decision.

Leyland told the Tigers after the end of the ALCS that he would retire, according to Rosenthal. Detroit lost the series 4-2 to the Boston Red Sox.

The 68-year-old had signed one-year contract extensions each of the past two seasons. His retirement comes as a bit of a shock; both Chris Iott off MLive and Tom Gage of the Detroit News expected him to return on another one-year deal.

Leyland has been the Tigers manager since 2006, compiling a 700-597 record with Detroit over the past eight seasons. The Tigers won two AL Pennants under Leyland, and have earned three consecutive AL Central titles.

Overall, Leyland managed 22 seasons in the majors for Pittsburgh Pirates, Florida Marlins, Colorado Rockies and Tigers. Leyland won a World Series in 1997 during his first season as Marlins manager.
