Gregg has signed a minor-league deal with the Reds and an invite to spring training, the team announced. The 36-year-old Kevin Gregg is likely at the end of his career, after a disastrous 2014 in which he gave up 10 earned runs in nine innings, then was shut down to have bone chips removed from his elbow. It's going to require a lot to convince the Reds he's worth a roster spot in the coming months.
