I'm generally opposed to trading anybody within the division, but if the Cardinals have something to offer for Tejada, would it be a good idea?
Joe Strauss mentions at the bottom of this article:
The Cardinals have expanded their search for an additional hitter to include Houston Astros shortstop Miguel Tejada. Tejada fits the profile of what the Cardinals are seeking — an offensive deterrent capable of playing multiple positions. The Astros are experiencing financial problems and could part with a player owed $13 million this season. Tejada entered Wednesday leading the NL in batting with a .357 average and 21 doubles. He ranked third in the league with a .354 average against righthanded pitching.
Buster Olney chimes in:
A big question about this situation is whether the Astros would ever trade one of their better players to a rival team. My guess would be that no team owned by Drayton McLane would do so.
