Source: Cards’ interest in Holliday ‘mild’ … for now

Don’t pencil Matt Holliday into the Cardinals’ lineup just yet.

Despite reports Thursday that St. Louis and Oakland are discussing a trade for the A’s slugger, one source with knowledge of the Cardinals’ thinking maintained that “there is nothing going on.”

St. Louis is exploring many options ahead of the July 31 non-waiver trade deadline, but the source said that, at this point, the Cardinals’ interest in Holliday is “mild.”

Holliday, whose offseason acquisition helped make the A’s a preseason sleeper pick in the AL West, struggled during the early part of the season. However, the right-handed hitting left-fielder has caught fire in July and raised his batting average to .287 entering Thursday. He also has 11 home runs and 54 RBIs.

St. Louis is looking for a big bat to complement Albert Pujols, who leads the NL in home runs and RBIs, and is second in batting average.

Discussions of a Holliday trade were first reported by the San Francisco Chronicle and ESPN.com.
