Line overflow when using biblatex citation

Question

Background

I have defined a set of citations in the following style in a .bib file.

    @inproceedings{McKinney.2010,
        author = {{Mc\-Kinney}, Wes},
        title = {Data Structures for Statistical Computing in Python},
        pages = {56--61},
        publisher = {SciPy},
        series = {Proceedings of the Python in Science Conference},
        booktitle = {Proceedings of the 9th Python in Science Conference},
        year = {2010},
        doi = {10.25080/Majora-92bf1922-00a},
        file = {McKinney 2010 - Data Structures for Statistical Computing:Attachments/McKinney 2010 - Data Structures for Statistical Computing.pdf:application/pdf}
    }

Now I try to reference the article in my text using biblatex with the following settings

\RequirePackage[backend=biber, style=authoryear]{biblatex}

as following:

This is my example text in which I try to use a citation (\cite{McKinney.2010}).

Problem

After rendering ( meaning in the pdf viewer ) the citation (McKinney.2010) is ending further right than the rest of the block text.

I want to ( preferably automatic ) insert an appropriate linebreak into the citation so that it does not show overhang.
