The Cardinals brought up Michael Wacha last year, he made a few starts, they transitioned him to the bullpen a little, and then they put him back in the rotation. Haven't we been down on that in-out type stuff? Wainwright's really the guy everyone's talking about. He was a September call-up in 2005 and made the team as a reliever in 2006. They then jumped his innings 127 and he started in 2007 and was pretty good, but not great. His ERA dropped a half point from 07-08, though his FIP only slightly, and it wasn't until 2009 that he started garnering Cy Young awards. Who's to say the year in the bullpen didn't delay his development? Lance Lynn did the reliever thing in 2011 and then in 2012 was a starter except for a month near the end of the season and then they stretched him back out near the end of the season to use him in the playoffs and he got bombed. I wonder if that end of season stretching out was bad for him? Shelby Miller got a 2012 September call up as a reliever and started in 2013. Joe Kelly has done half and half in 2012 and 2013. They stretched him out last June for the rotation. It's certainly one way to do it, but It's probably not the best way. Nor the only way. And was at least partially born of necessity. And isn't Mejia an example of it too, and one that is almost universally criticized? Aren't Germen and Familia both examples? They transitioned Germen to the bullpen last year. They also transitioned Familia to the bullpen last year as well, after he got a September callup in 2012 as a reliever. The Cardinals prospects worked out better in terms of ceiling, but the process looks very similar. And there's been plenty of talk of guys like deGrom getting called up, and maybe even Montero, but for the sake of those guys development, they're starting where they can start, but that's a lot more valuable. It's not like those guys are locks to be lock-down relievers at this point in their development either. Their growing pains could very well be worse than Kyle Farnsworth. I'm all for molding the development plan of our young arms to those players, not to the whims of the major league roster.
