ARLINGTON  (AP) - Texas Rangers general manager Jon Daniels has received a four-year contract extension through the 2015 season.

Daniels joined the Rangers organization as a baseball operations assistant in 2002. When he became general manager in October 2005, he was only 28 years old and the youngest GM in the history of major league baseball.

Texas is coming off its first-ever World Series appearance, which came after Daniels helped overhaul the team's farm system and made several key trades.

Daniels dealt Mark Teixeira to Atlanta in July 2007 in a deal that got Texas shortstop Elvis Andrus and hard-throwing Neftali Feliz, the AL Rookie of the Year last season with 40 saves.

The Rangers announced the deal on Friday.
