Actually Dancevic is well-known for his erratic behaviour... he retired down 3 MPs against Janowicz, for example.
Yes but do you know why he retired in the match you listed? Janowicz-match has nothing to do with it. An erratic player can still get injured. I´m just saying many of these matches deserve the benefit of doubt, unless you ( or someone else) actually has some idea what really happened in a match. The scoreline is hardly relevant by itself.
