10:50am: The Giants “don’t have a strong enough package of prospects” to land Hamels, Bob Nightengale of USA Today tweets.

8:20am: The Giants are “making a strong push” for Phillies lefty Cole Hamels, Ken Rosenthal of FOX Sports reports on Twitter. San Francisco has previously been mentioned as a suitor, but it appears that the team is looking to make a serious attempt at landing the lefty.

Of course, we heard yesterday that the Astros, too, were also driving after Hamels. And there were indications that the Diamondbacks had entered the conversation as well. It’s not yet clear, though, that clubs with more long-standing interest — particularly, the Rangers and Dodgers — have been displaced as the likeliest landing spots.

From the Giants’ perspective, yesterday’s news suggested that the club was interested in adding a starter, but only if it was a significant upgrade. And San Francisco did not seem terribly likely to actually pull something off.

It remains to be seen, of course, whether the run at Hamels will amount to anything. The Giants do have forward-looking financial flexibility, as Rosenthal notes on Twitter, but the same could probably be said of several other teams reportedly in the hunt. It’s not clear what kind of package the team would be interested in dangling, though young catcher Andrew Susac would seem likely (in my opinion) to hold significant interest to Philadelphia.

Hamels could block a deal to the Giants, who are not on his list of nine teams to whom he can be dealt without consent. (Jim Salisbury of CSNPhilly.com tweeted the updated list recently.) It’s not clear at present whether that would pose any issues.
