According to Rick Hummel of the St. Louis Post-Dispatch, Cardinals chairman Bill DeWitt Jr. said the Cardinals are "open" to making trades, but won't deal just for the sake of making a change. Since many teams are still trying to contend, some big names are not yet available.
"I'm not certain a market's developed for any of the players who would help us," DeWitt said.
The Cardinals can afford to take on payroll, something many teams are reluctant to do. This means players like Matt Holliday are options if they become available. Holliday makes $13.5MM this season and any team trading for him would have to give up quality prospects as well. For now, and until the A's stop winning, it's a moot point. The A's aren't talking trades.
