Sreesanth, Santh, or Srisanth?

I like to concern myself with the really important matters that effect world cricket (incidentally, should that be effect or affect?), so I couldn't help but wonder why one of the Indian bowlers appears to have 3 names.

Sreesanth on Cricinfo
Santh on BBC
Srisanth in an Indian article I saw

The poor fellow must feel a little put out that people can't get his name right. Whatever his name is, his profile on Cricinfo is here.
