Milwaukee-Brandon Phillips led off Tuesday against the Milwaukee Brewers.
Juan Castro started at shortstop for Felipe Lopez, and Ryan Freel did not start.
"Without Freel and Lopez, it falls to (Phillips)," Reds manager Jerry Narron said. "Honestly, I feel comfortable with wherever he hits. I think he's going to give us a good at-bat."
Phillips went 1-for-3 with a walk. He had his string of 16 straight successful steal attempts snapped in the first inning.
It was Lopez's third day off in a week.
"It's been a grind here before the All-Star break," Narron said. "I'm trying to get Juan out there as much I can."
The addition of Castro gives Narron another alternative at shortstop - a sure-handed one and a right-handed-hitting one. (Lopez is hitting .209 against right-handers.) Castro makes it easier to rest Lopez, Narron said.
