Rockies closer Huston Street said Sunday that he hopes to return in late April from shoulder stiffness. Street said after back-to-back throwing sessions on Friday and Saturday "it didn't go any better, but we are going to stay with the throwing program, see if we work through it." Street has already been shut down twice this spring because of the stiffness, but the rest did not alleviate the problem. "We have set a time frame which we hope will have me back by the end of (April)," he said.
