Lawyers for Jason Giambi and Major League Baseball spent yesterday trying to finalize an agreement that would set up a meeting between steroids investigator George Mitchell and the injured Yankees slugger.

Giambi, facing a Thursday deadline to agree to meet with Mitchell or else face posssible discipline from commissioner Bud Selig, reportedly has finalized the parameters of negotiated Q&A testimony about his personal use of performance-enhancing drugs and his grand jury testimony in the federal BALCO case.

According to ESPN.com, a sticking point has come up "at the half-yard line" that is preventing the agreement from being completed.
