Not that I have too much time on my hands

- but I used the Winner/UE stats at matchstat.com to see how the top 10 compared.
I know Winner/UE stats are notorious for potential subjectivity, but thought it was at least worth a look.

As I mentioned earlier in the thread, I've always thought of Maria as the most 'bash-prone' of the top players. For 2011 and 2012 combined she tops the stats for the UE ratio (ahead of Na and then Petra), but is 3rd (behind Serena and Petra) for the winners ratio.
Which would indeed imply that for the last two years, Maria has been (on average, and only just) the player least able to control her aggressive play at the slam level
