"Pitcher Aaron Harang and the Reds gave it their best effort. But all the chiropractic adjustments, ice and stimulation could not get Harang's back loose enough for him to make the start Tuesday night.

Harang instead was placed on the 15-day disabled list, retroactive to his June 30, with lower back spasms.

Left-hander Matt Maloney made the start Tuesday for the Reds.

"We waited until the chiropractor came in again," Reds manager Dusty Baker said. "He's a little bit better but not good enough to pitch. We anticipated this. That's why we had Maloney here."

"You know those backs, boy; they usually don't let you go too quickly."

Maloney was scheduled to start for Triple-A Louisville Tuesday.

"Things aligned for us," Baker said.

Harang is eligible to come off the disabled list July 16 – the day after the All-Star break ends. That means he'll miss a total of two starts.

The Reds will need a starter for Sunday as well. Baker wasn't ready to commit to Maloney for that one.

"I don't know yet," Baker said. "If you're in a situation like we've been in, we're using everybody and anybody who's throwing the ball well.

"We certainly hope so. That means he threw the ball well here."

Maloney was 6-5 with a 3.50 ERA in 15 starts at Louisville.

"He's a young man who's been next line and had people jump over him by performance," Baker said, "especially in spring training with (Travis) Wood and (Mike) Leake.

"He was throwing the ball well down there. He's excited about this opportunity."

The Reds currently have three rookies in the rotation – Maloney, Wood and Leake.

"We're lucky we have the depth we do," Baker said."
