From the Baltimore Sun’s Jeff Barker.

A congressional committee is investigating whether another Orioles player gave Rafael Palmeiro a substance that might be linked to the first baseman’s positive steroid test, according to people familiar with the investigation.

The scenario of Palmeiro receiving a substance from a teammate was described by Palmeiro himself in closed-door proceedings before a three-member baseball arbitration panel earlier this year as he presented his steroid defense, one source said. A second source confirmed the account and that Palmeiro had identified the teammate by name. The sources declined to be identified because the congressional investigation is ongoing.

It would be shameful to start guessing which Bird was implicated by Raffy.

Though if I’m Miguel Tejada, I’m royally pissed (at being 18 games out of first place).
