Manager Walt Weiss has agreed to a three-year contract extension with the Colorado Rockies. The Rockies and manager Walt Weiss, who presided over a 10-win improvement this season, reached a three-year contract agreement on Tuesday. Terms were not disclosed. Weiss, who turns 50 on Nov. 28, took the job last Nov. 8 under a one-year contract. The 49-year-old Weiss came out of the high school coaching ranks last year on a one-year deal with the Rockies after Jim Tracy stepped down following a 64-98 season in 2012. Weiss, a Rockies shortstop from 1994-97 and the first former Colorado player to manage the team, worked as a special assistant to the general manager from 2002-08 before leaving professional baseball to coach his sons at Regis Jesuit High School in nearby Aurora as an assistant from 2009-11 and a head coach in 2012. He also spent seven seasons, from 2002-08, as a special assistant to the general manager with the Rockies. Their 74-88 final record left them last in the division for the second straight year the first time in club history it has had consecutive last-place finishes but they did win 10 games more than the previous season.
