Alex Trevino and Alan Ashby split the catching duties for the 1988 Houston Astros, but rookie Craig Biggio managed to snare enough at-bats to turn some heads. Eighteen seasons later, the 40-year-old mainstay enters Spring Training as Houston's starting second baseman. The seven-time All-Star spent four years behind the plate in Houston, before shifting to second base for 11 seasons (where he won four Gold Glove awards), then to center field for two seasons before returning to second base in 2005. Biggio remains a Houston fixture, and a key component to their quest to return to the World Series.
