Sources: Holliday, Cards close

The St. Louis Cardinals and free-agent outfielder Matt Holliday continue to make progress and are close to a deal, sources told ESPN The Magazine's Buster Olney.

Talks between Holliday, who is considered the prime free-agent hitter remaining on the market, and the Cardinals have centered on a possible seven-year deal.

The three-time All-Star came to St. Louis from the Oakland Athletics in a July deadline trade last season. He batted .313 with 24 home runs and 109 RBIs between the two clubs.

Holliday is a career .318 hitter in six seasons.
