The Baltimore Orioles apparently are ready to step to the bargaining table. The Orioles would be willing to trade franchise shortstop Manny Machado to the Yankees if New York includes left-handed pitching prospect Justus Sheffield in the return package, MLB Network’s Jon Morosio reported Wednesday, citing a source. A Yankees-Orioles blockbuster is by no means a done deal, though: according to Morosi, there’s “skepticism” the Yanks would part with Sheffield to acquire a rental, as Machado will become an unrestricted free agent this offseason. Part of New York’s “skepticism” is understandable: ranks Sheffield as the No. 2 prospect in the Yankees’ system, and there’s a chance the 22-year-old hurler, who was promoted to Triple-A in early May, could break into the big leagues later this season.
