The Nationals have designated corner infielder Greg Dobbs for assignment, reports Adam Kilgore of the Washington Post (via Twitter). The move creates roster space for the promotion of pitcher Taylor Hill.
Dobbs, 35, was picked up mid-season after being released by the Marlins. He has largely struggled in a limited bench role, and owns a .171/.186/.195 line through 43 plate appearances on the year. Over parts of 11 seasons in the bigs, Dobbs has slashed .261/.306/.386 over 2,272 plate appearances.
Hill is a 25-year-old righty who was taken in the sixth round of the 2011 draft. He has risen steadily through the system, and currently owns a 1.92 ERA with 6.2 K/9 against just 0.9 BB/9 through 93 2/3 frames in his first extended time at Triple-A. Though he has worked as a starter in the minors, Hill will presumably slot into the Nationals pen for his first MLB action.
