Claiming the Chicago Cubs coveted Aaron Heilman “because he went to Notre Dame” (!), ESPN.com’s Jayson Stark alerts us to Tuesday’s biggest trade that-didn’t-happen.

The Mets and Cubs have discussed a trade that would send pitcher Jason Marquis to New York for reliever Aaron Heilman. But chances of that deal happening appeared slim Tuesday.

The Mets are looking to move Heilman because they’re concerned about whether he can still pitch in New York. The Cubs need to trade Marquis to clear money for the acquisition of a left-handed hitter and a possible deal for Jake Peavy.

But Marquis’ $9.875 million salary was too hefty for the Mets’ liking. And while the Cubs have expressed willingness to eat some of that money, the teams have been unable to agree on a figure acceptable to both sides.

While the Mets’ signing of reliever Francisco Rodriguez is said to be imminent, the Giants are supposedly on the brink of having committed a quarter billion dollars to a pair of starters. From Insidesocal’s Tony Jackson :

As the Dodgers’ deals with Mark Loretta and Casey Blake appear to be either done or close to done, it might not help their effort to sign CC Sabathia, something the Dodgers aren’t expected to try to do until they fill their shortstop vacancy. The word around here is that Giants officials are supremely confident that they are going to sign the big lefty, this despite the fact they are already paying all that money to Barry Zito. If Sabathia does sign with the Giants, that would dramatically change their prospects in the very-winnable N.L. West next season.
