The answer is........perjury.
The Astros traded for star shortstop Miguel Tejada last December only a day before baseball's Mitchell Report named Tejada as a past steroid user. Now the Astros are reportedly trying to trade Tejada. But interested teams should know there could be another surprise in Tejada's future.

Tejada is being investigated for possible perjury after telling the US Attorney's Office he had not used steroids or discussed them with teammates. According to the Mitchell Report, former teammate Adam Piatt provided checks signed by Tejada for what Piatt said was a steroid buy.

FBI Washington field office spokesperson Debra Weierman told SI's Melissa Segura the investigation is ongoing.
Astros are now officially stuck with Tejada. They're just glad its for only one more year. Tejada had a decent year for the Astros in his first year in the NL and amid a steroid and age fraud cloud. Should be interesting if he does any better this year.
