B.J. Upton Rumors: Tuesday

The latest on Rays center fielder B.J. Upton, who owns a .229/.310/.399 line on the season:

• The Rays had a scout watching the Nationals' Triple-A team yesterday, tweets Joel Sherman of the New York Post.
• The Giants are showing strong interest, tweets SI's Jon Heyman.
• The Indians, Giants, Braves, and Pirates are among the teams in on Upton, report Jon Paul Morosi and Ken Rosenthal.  The Royals are not seriously pursuing Upton, while the Brewers, Rangers, and Phillies are not involved.
• The Nationals have balked at trading pitchers Ross Detwiler or Brad Peacock for Upton, reports ESPN's Jayson Stark.  One executive says the Giants have moved in.
• Five teams are "in play" for Upton, a source tells Jon Paul Morosi of FOX Sports (Twitter link).

My apologies for an earlier error in which I erroneously attributed Joel Sherman's "asking for a ton" quote to the Rays and B.J. Upton.  The quote actually referred to the Cardinals and Colby Rasmus.
