Chris Anderson pitched shutout ball into the seventh inning and the Arizona Diamondbacks sent the Cincinnati Reds to their ninth straight loss, 4-0 Sunday. Welington Castillo and David Peralta homered as Arizona completed its first four-game sweep over the Reds. Cincinnati matched its longest skid of the season. Raisel Iglesias (3-5) struck out 13 in seven innings, the most by a Reds rookie since Gary Nolan fanned 15 Giants in 1967.
