The Marlins have not abandoned the notion of acquiring Tampa Bay center fielder Joey Gathright, but the two teams are having trouble matching up. The Devil Rays are believed to have requested two of the Marlins' premium pitching prospects, more than the Marlins have offered. Houston center fielder Willy Taveras also is being monitored. He could become available if Jeff Bagwell proves healthy enough to play first base. It would move Lance Berkman back to the outfield and make Taveras expendable, particularly for young, major league-ready pitching.
