According to the The Baltimore Sun today, Pitching coach Ray Miller may not return next year due to health issues:

Miller will undergo surgery after the season, a procedure that he's keeping private. He'll say only that it's "serious" and that he can't make any decisions about his professional future until it's completed.

He's also waiting to find out whether Perlozzo returns and if any changes are made in the front office. Jim Beattie and Mike Flanagan won't be under contract after October.

"It would depend on who the manager is, and if they even want me," Miller said. "I don't even know who the GM is going to be."

Well, Ray says he wants this to be private, so I won't speculate on what the problem is, but here's hoping whether he is in an Orioles uniform or not next year (and I hope he is), he has many years of good health ahead of him. Best of luck Ray!
