The Nationals may be in the process of sending reliever Drew Storen to the Twins in exchange for outfielder Denard Span. Storen, in his second year in the bigs, is 5-2 with a 2.68 ERA and 41 strikeouts in 50 1/3 innings pitched. Span is hitting .294 with two homers, but he's been on the disabled list since June 9 with a concussion.
