The Arizona Diamondbacks split their four-game series with the San Francisco Giants, falling to 2-5 in their recent homestand. The D-backs are 43-44, back below .500 and sit 3.5 games out of a Wild Card berth. The Royals, meanwhile, have endured a dismal stretch of baseball. Left-hander Eduardo Rodríguez has been one of the D-backs’ best arms since he returned from the injured list.
