Gerardo Parra drove in three runs and threw out a base runner Thursday, leading the Arizona Diamondbacks to a 6-5 victory over the Cincinnati Reds.
Willie Bloomquist had three hits, including a double, and drove in a run.
The Reds built a 4-1 lead against starter Ian Kennedy and left-handed prospect Tyler Skaggs. Parra and Bloomquist helped put the Diamondbacks on top.
The Reds' Joey Votto walked and scored in three plate appearances.
Cincinnati opened its competition for the fifth spot in the rotation. Right-hander Mike Leake, trying to retain his spot, pitched two innings, allowing a run on two hits. Left-hander Aroldis Chapman, last year's closer who is competing for a rotation spot, started a split-squad game against Colorado and retired all six batters he faced, fanning one.
