The Nationals have signed infielder Mark Minicozzi to a minor-league deal. Minicozzi, 31, hit .298/.400/.470 with 12 home runs and 62 RBI in 315 at-bats with Triple-A San Jose in 2014. He has yet to appear in a regular-season game in the majors.
The Giants optioned pitchers Heath Hembree, Erik Cordier and Jake Dunning to Triple-A Fresno Friday. Hembree allowed just one earned run on one hit and two walks in four innings while striking out five in five Cactus League appearances this spring. The Giants also reassigned catcher Guillermo Quiroz, first baseman Mark Minicozzi and pitchers Brett Bochy and Adam Reifer to minor-league camp Friday.
