Monday: Olney adds that the Phillies are focused on acquiring help at third base and in the outfield in any trade for Hamels (Twitter link).

Sunday, 2:30 pm: The Phillies' asking price for Hamels is said to be a package of four to five prospects, tweets Buster Olney of ESPN.com. Olney adds rival executives believe such a package could be hard to come by with the new rule preventing teams from offering arbitration to potential free agents acquired in trade (via Twitter).

12:22 pm: The Phillies have begun calling teams to see about trade interest in Cole Hamels, tweets Jon Heyman of CBSSports.com. The left-hander will be eligible for free agency after earning $15MM in his walk year. Heyman writes there has been no progress made in contract negotiations.

It's possible that the Phillies are just scoping out early interest in Hamels just in case, Heyman tweets, but the calls make the odds of a trade seem real at this point. Less than a week ago, it was reported that the club was not ready to put Hamels or outfielder Shane Victorino on the block.

There should be no shortage of interest in the 28-year-old and the Rangers could be one of the more aggressive suitors for him. Texas is said to be scouting Hamels as well as Brewers pitcher Zack Greinke.
