"If the Yankees are indeed interested in acquiring Kansas City Royals All-Star closer Joakim Soria, they will face one more hurdle -- a no-trade clause.

The Yankees are one of the six teams on Soria's no-trade list, a baseball official with knowledge of the contract tells ESPN New York.

Rumors have been circulating that the Yankees want to make Soria their new eighth-inning man to replace Joba Chamberlain.

The no-trade clause is one hurdle, but the biggest mountain that Yankees general manager Brian Cashman must move is the Royals' reluctance to trade Soria. Kansas City has told teams it will listen on Soria, but it will take a boatload of talent to acquire the right-hander."
