The Pirates have signed infielder Jayson Nix, optioned Brent Morel to Indianapolis and designated Dean Anna for assignment. Nix will be in uniform for this afternoon's game.
I think Anna is actually the highest-upside player of the three, but they're all replacement-level-ish infielders, so none of this matters too much. Nix, who's 31, has spent most of this season playing with the Rays' Triple-A team, hitting .274/.341/.411. He's a plus defensive player who can play six defensive positions, including shortstop, so that's something. He's unlikely to hit much, however.
