The Houston Astros rewarded manager Phil Garner on Monday for leading the club to its first World Series by extending his contract by one season 2007. With his trademark mustache and occasionally unexpected moves, Garner has guided the Astros to a 137-99 record over 1 1/2 seasons. Houston won its first playoff series last year and made the World Series this season before getting swept by the Chicago White Sox. The Astros needed big comebacks to win wild-card berths both seasons, overcoming a 15-30 start this year to become the first team since the 1914 Boston Braves to reach the World Series after falling 15 games under .500. "We are very pleased about the performance of our team under Phil," team owner Drayton McLane said. "It is an exciting time for the Houston Astros, and we feel Phil's leadership and efforts have contributed greatly to our success. We look forward to having him as our manager as we continue our mission toward a World Series championship."
