With Carlos Beltran headed to the Giants, the market for Rays center fielder B.J. Upton appears to be shaping up. The Nationals, who have long coveted Upton, are believed to be the front-runners by some. The Braves, Indians, Phillies, Reds and Pirates are also believed to be interested in Upton's services. "I really don't know how this is all going to shake out," Tampa Bay manager Joe Maddon said. He also said he would "love" for Upton to stick around.
