ROSTER MOVE: #Dbacks acquire 3B Chris Johnson from #Astros in exchange for @MarcKrauss25 and Bobby Borchering.

The makeover at third base continues. Five days after trading Ryan Roberts to Tampa, the D'Backs have acquired Astros third baseman Chris Johnson for prospects Marc Krauss and Bobby Borchering. It is likely he will slot into the starting third base role, and another roster move will be forthcoming to make room on the roster. Johnson has been hitting .279/.329/.428 with 8 Home Runs and has been worth 0.5 bWAR so far this year for the Astros. It screams "Average", but average is better than what the D'Backs have been getting from the hot corner this season.

In return, The D'Backs send Borchering and Krauss, who were first and second round picks in the 2009 draft, respectively and were both in Double-A Mobile. Borchering was recently promoted, and had been struggling, hitting only .180. Krauss was low on the outfield depth chart, behind guys like Adam Eaton and A.J Pollock. According to Nick Piecoro, those two were never held in high esteem by the Kevin Towers regime, and perhaps a move to the Astros organization will be a fresh start for them.

We will report on the corresponding roster move when it happens.
