When will Johan Santana return in 2011?

Here is back and forth from Anthony DiComo’s most recent chat on MLB.com:

Last week, on WFAN, Sandy Alderson said he does not expect Santana to be ready for Opening Day, but feels it is ‘reasonable’ to expect him back by the All Star break, adding, ‘it could be before that, could be slightly later,’ but, either way, they will have him for the second half.
