New York Yankee Player Profiles: Aroldis Chapman, what's ahead for the closer?

The New York Yankees have a host of problems this season; they hope Aroldis Chapman, the Yankee closer, isn't one of them. He started the season as sharp as ever. He had a 0.00 ERA from the beginning of the season until May 23rd, when he blew his first save against the White Sox. That's 18 games in a row. Following that, there were a few blips but nothing of concern, but the last month has been very concerning. On June 23, he gave up 2 runs to the Royals; on June 30, he gave up 4 runs to the Angels while only recording one out. Then, on July 4th, he wasn't celebrating Independence day when he gave up 3 runs to the rival New York Mets, this time without recording an out.
