Aroldis Chapman gave up a home run to Andy Parrino of the Padres among the four that he allowed in three innings but that was the only run.
Chapman walked seven batters per nine innings out of the Reds bullpen last year and vows to stop the free passes. He allowed none today.
"No one had to tell me," Chapman said. "I knew I had to cut down."
Chapman allowed that his concentration waned at times last year for worrying about personal matters.
He is working on a split finger fastball. The Reds asked him not to throw it the first couple years here in Cincinnati but as a starter he needs another pitch. He is using it now in place of a change up.
Todd Frazier hit a two-run double and continues to make a case for earning a backup role with the Reds. He leads the team with three doubles and three home runs. He is tied with Daniel Lutz for the RBI lead with eight.
Brandon Phillips younger brother PJ shared the field for the first time in their lives for a half inning. PJ singled in his first at bat and flied out to deep left in his other at bat. PJ played centerfield. He is currently listed on the Reds Triple A roster at Louisville.
