"Baseball's labor negotiators have reached a "handshake agreement" on all major issues, and the sport's new five-year collective bargaining agreement is likely to be announced Tuesday, sources told ESPN.com Friday.

The sources were hesitant to use words such as "done" or "over" to describe the negotiations, because the two sides are still in the process of putting the agreement into writing. However, one source went so far as to say there are "no issues that remain to be negotiated."

A second source was even more reluctant to characterize the new agreement as a finished product, saying: "Either there is a signed labor deal or there isn't -- and right now, there isn't."

Nevertheless, all that stands in the way of an announcement at this point, sources said, is the writing of a legal document detailing changes between the old Basic Agreement and the deal the two sides have been negotiating for months.

The sides have essentially been in agreement on most significant issues for several days. But following this week's owners meetings, they met outside Chicago on Thursday evening to settle on the specifics on a number of matters that had needed to be resolved before the agreement could be put in writing. That session concluded early Friday."
