Team officials for two of the clubs in talks with the Mets expect discussions to continue until next weekend, according to Adam Rubin of ESPN New York (on Twitter).
The Giants, Braves, Phillies, Red Sox, and Rangers have each had a scout on hand to watch Beltran this weekend, tweets Jon Paul Morosi of FOX Sports.
Yahoo's Jeff Passan says (via Twitter) the Rangers are "coming hard" for Beltran, though San Francisco is still the frontrunner. Passan singles out Giants prospect Francisco Peguero as one name that may have been discussed.
The Red Sox see Beltran as a "total longshot," and are more concerned with adding pitching, according to ESPN.com's Buster Olney (via Twitter).
In his Insider-only blog, Olney says the Mets are looking for a top pitching prospect from the Braves - perhaps Mike Minor, Julio Teheran, Arodys Vizcaino, or Randall Delgado. One talent evalutor says he can't see GM Frank Wren parting with any of those four arms for Beltran.
Andy Martino of the New York Daily News looks at Minor and a few other prospects the Mets may be targeting in Beltran discussions.
