1:40pm: MLB.com's Todd Zolecki learned from Castro's agent Oscar Suarez that he's closing in on a deal with the Phillies. As Suarez put it: "Who doesn't like Juan Castro?" Scott Lauber of The News Journal says only a physical remains, and David Murphy of the Philadelphia Daily News says an agreement has been reached on a one-year deal with a club option.
1:11pm: Andy Martino of the Philadelphia Inquirer believes the Phillies are the frontrunner to sign Castro, though no deal is imminent.
11:50am: Ken Rosenthal and Jon Paul Morosi of FoxSports.com report that both the Dodgers and Phillies are pursuing utility infielder Juan Castro. The Phillies are looking at him as a replacement for Eric Bruntlett (who isn't likely to return), while Dodgers are trying to retain him after he hit .277/.311/.339 in 121 plate appearances for them last year.
The 37-year-old Castro signed a minor league deal with LA last season, though he spent basically the entire season in the big leagues. He made $700K while playing three infield spots and left field in 2009.
