Aroldis Chapman's season is one of the great mysteries of this baseball season. Let's break his season into three segments:

Segment 1: 12 games, 112/3 innings, 4 hits, 0 runs, 8 walks, 13 strikeouts

Segment 2: 4 games, 11/3 innings, 2 hits, 10 runs, 12 walks, 3 strikeouts

Segment 3: 6 games, 6 innings, 2 hits, 1 run, 1 walk, 12 strikeouts

Of course, a lot happened between Segment 2 and 3.

Chapman was placed on the disabled list with shoulder inflammation. He spent five weeks on the DL. He made a total of nine rehab appearances. Seven of them were not good.

He had an 11.12 ERA at Triple-A Louisville and a 6.14 ERA at Double-A Carolina.

But since his return from the DL, he's been better than ever.

"He's been terrific," Reds pitching coach Bryan Price said. "He's a completely different guy."

Price could take credit for Chapman's turnaround. Instead, he's at a loss to explain.

"It's hard to put a finger on because none of us really know the path that he's followed to get here," Price said. "We don't know what experiences he's experiencing for the first time. Everything that's happened has unfolded in such a public forum.

"He's an attraction. So when he was struggling with his command - having to deal with that in this kind of environment heightened the sense of urgency, panic or confusion or whatever it may be."

"I don't know that I can put my finger on it."

Chapman, Price and manager Dusty Baker say he worked very hard to get out of the funk.
