Diamondbacks signed RHP Matt Foster to a minor league contract.

The former White Sox’ right-hander had been pitching for the Algodoneros de Union Laguna in the Mexican League where he registered a stellar 0.66 ERA, 0.66 WHIP and a 13/0 K/BB ratio across 13 2/3 innings of work. He’ll provide extra bullpen depth in the upper minors for the Diamondbacks.
