Castillo (1-1) allowed three hits over 6 2-3 innings, striking out eight with a walk. It was his longest outing of the season.
Castillo, in his fourth career start, held the Diamondbacks hitless for the game’s first three innings, then after giving up a single to Paul Goldschmidt retired the next nine Diamondbacks.
Votto drove in three runs.
The Diamondbacks managed only the three hits and lost their fourth game in the past five.
