Changing that one comma to a semicolon is a given. The question is whether there should be a comma after "Mary" -- and there should not. You never want to separate a subject from its verb with a comma. Here is a good webpage that explains comma uses: http://grammar.ccc.commnet.edu/grammar/commas.htm
You'll not find a single one of those reasons that justifies using a comma after the subject of a clause or sentence.
