Houston Astros first baseman Jeff Bagwell said Saturday he will start the season on the disabled list and isn't sure if he'll return this year. The 37-year-old Bagwell, perhaps the most popular player in franchise history, spent the spring in a contentious battle with the team while he tried to prove he could still play despite a chronically injured right shoulder. The Astros filed an insurance claim in January to recoup about $15.6 million of the $17 million Bagwell is guaranteed this season in the final year of his contract, arguing he is too hurt to play. He must stay on the injured list all season for the Astros to collect their money.
