The Philadelphia Phillies are aggressively pursuing Matt Holliday, sources tell SI.com. The Rockies surely would be interested in Phillies centerfielder Shane Victorino, but it isn't known whether Philadelphia would consider moving him. The Phillies have several other well-regarded young players, including catcher Lou Marson, shortstop Jason Donald and pitcher Carlos Carrasco. Sources indicate that the Phillies have enough good young players to be able to do a deal for Holliday if the sides can agree. Several teams have shown interest, including the A's, Mets and Rays, but so far it appears the Phillies may have the best chance among those teams.
