Nationals Making Headway On Acquiring Span

10:47pm: The Nationals are more likely to go after Span than Michael Bourn or B.J. Upton at this point, according to ESPN.com's Buster Olney (on Twitter). Jon Paul Morosi of FOX Sports hears that the sides are in a "staredown" (Twitter link). The Twins want the Nationals to include Storen in their offer.

9:22pm: The deal is "no closer than any other day," an MLB official told Joe Christensen of the Minneapolis Star-Tribune.

6:31pm: A deal featuring Span and Storen continues to look close, according to Ken Rosenthal of FOX Sports (on Twitter).

6:08pm: The Twins are insisting on acquiring Storen with Bernadina and minor league infielder Stephen Lombardozzi for Span, according to Jim Bowden of ESPN.com (on Twitter).

5:18pm: There are lots of mixed signals about the talks, but no deal is close, according to Jon Paul Morosi of FOX Sports (on Twitter).

3:28pm: The Nationals are making headway with the Twins on a deal for Span, tweets ESPN's Jayson Stark.  The Twins are insisting Storen be included along with a second player.

1:50pm: The Twins want Roger Bernadina along with a reliever in any deal that sends Span to the Nationals, tweets Adam Kilgore of the Washington Post.

10:45am: The Nationals are pushing setup man Tyler Clippard on the Twins for center fielder Denard Span over closer Drew Storen, tweets Scott Miller of CBS Sports.  He says the Twins won't trade Span for a setup man, however.

Aside from saves, Storen comes with one more year of team control than Clippard.  Still, we're talking about 2015 and 2016, and there's no telling what can happen with relievers in the course of several years.
