"With what's happen with Matt, it's not time to take chances," Collins explained.
Wheeler will not undergo any tests on his shoulder at this time - the stiffness is being attributed to fatigue.
Wheeler went 7-5 with a 3.42 ERA in 17 starts after being recalled from Triple-A Las Vegas in mid-June. He threw 100 innings in the big leagues, and 68 2/3 innings with the 51s this season. He threw 149 innings in 2012.
Everyone in the organization - including Wheeler - stressed the importance for Wheeler to go through the grind of a full season. He got close, but there is absolutely no reason to push Wheeler with a stiff shoulder. In the end, he had an outstanding first year, adjusted and grew as the season went along and learned to experience the big league life, a goal for both him and the organization in this transition season. I expect more growth for Wheeler next season as he takes these next important steps in his professional career - that will begin with his second big league camp and a secure roster spot heading into Opening Day next year.
