Barnhart had a double and a triple in Wednesday's loss to the Pirates, raising his line to .279/.329/.426 over 68 at-bats.
With Devin Mesoraco out for the season, Barnhart will be the Reds' primary catcher, with little in the organization on the way to unseat him. He slugged just .326 last year, with only 12 extra-base hits in 242 at-bats. He now has seven extra-base hits already this year.
