Left-hander Aroldis Chapman was not available to pitch Thursday after going two innings and 35 pitches Wednesday.

"He may not be available (Friday) either," Reds manager Dusty Baker said. "It depends on how he feels."

If Chapman had gone one inning, he'd be available. He's being treated like everyone in the bullpen – to a degree.

"We treat him like any other reliever, but we've got a lot invested in the guy," Baker said. "Time, future and money. We're aware of that. We're always aware of that – with anybody.

"We know they're all not available."

Alfredo Simon wasn't available Wednesday. Logan Ondrusek wasn't Thursday.

"This early, guys are trying to get acclimated to back-to-back days and the workload," Baker said.

Chapman has gone two innings in two of his three outings.

"He could go more," Baker said, "from being stretched out in spring training. The more you stretch him out the more time you have to give him in between."
