Late Sunday, rumors started flying via Twitter that Prince Fielder was about to sign an eight-year deal with the Nationals, with an opt-out after three years.

Sounds pretty specific, right? A done deal?

Not so fast, tweeted Jim Bowden of ESPN/XM Radio:

The Nationals continue to work on a deal for Prince Fielder…BUT THERE IS NO DEAL repeat NO DEAL as of tonight according to sources

The non-deal was also noted on Twitter by Brewers beat writer Tom Haudricourt:

A very good source just told me there is no deal in place between Nationals and Fielder. Doesn’t mean it won’t happen at some point.

Orioles reporter Jen Royle says there might be another team in the mix:

Source: Orioles trying to squeeze $$$ out of Peter Angelos for Prince Fielder. Heard Showalter met with owner late last week & asked for $

That would be a big splash for the Orioles, especially since they share a market with the Nats. As always, we await further developments.
