General manager Brian Cashman has signed a three-year contract to remain with the New York Yankees, the American League team said on Tuesday.

Cashman, 44, has been the Yankees' GM since 1998, helping the team to four World Series titles and six American League championships. His previous contract expired on Monday.

The announcement comes a day after Cashman signed standout left-hander CC Sabathia to a contract extension that could keep with the team through the 2017 season.
