MLB Rumors: Cliff Lee holds the key to the MLB free agency puzzle.

Whenever and wherever he signs, Lee is expected to have a ripple effect throughout all of baseball.

And perhaps no one’s future will rely on Lee’s signing more than Kansas City Royals pitcher ZackGreinke.

According to Bob Dutton of the Kansas City Star, the market for Greinke will heat up once Lee is off the market.

The reported asking price for Greinke?

Dutton says the Royals wants”two high-impact prospects, preferably a starting pitcher and either a middle infielder or center fielder, and two players capable of supporting roles.”

Damn, that sounds like a lot.

Greinke is coming off a so-so season, and it’s unclear how many teams would be willing to part with that much talent to acquire a pitcher who’s not a surefire ace.’s Ken Rosenthal notes that the Marlins have been in touch with the Royals aboutGreinke’s services but nothing is on the horizon.
