    Righthander Kelly gets results, but does it with a lot of funk and deception. He sinks an average fastball that touches 92 mph, and he throws it for strikes. But he's rigid with an "iron Mike" delivery, and as one scout put it, "You just don't see guys pitch like that in the big leagues." Kelly mixes in a breaking ball, but it's his above-average changeup that is his second-best pitch. Because of his mechanical issues, he profiles better as a reliever in pro ball.
