The Reds have claimed infielder Jake Elmore off waivers from the Athletics, as Jane Lee of MLB.com reports on Twitter. In a corresponding move, the team has announced that it designated righty Nick Christiani for assignment.
Elmore, 27, had been playing in Triple-A after being added in a trade over the offseason. He has some past big league experience, however, with 209 total plate appearances. Over 211 trips to bat this year at Triple-A, he owns a .282/.374/.365 line.
Christiani, also 27, has not been successful in a 13-inning tryout this year, allowing eight earned runs and striking out only eight batters against six walks. He moved quickly to Triple-A after being drafted in the 13th round in 2009, and has put up solid enough results there (until this season, at least; he carries a 7.71 ERA).
