Hughes's effort of
125.25 average against Robbie Green; which was in the first European Tour qualifier of the season still tops the highest averages. Rob Cross is second and also has an effort in sixth place against Jan Dekker & Mike de Decker in consecutive UK Open Qualifiers.
Interestingly enough there are eight efforts of 111.33 made this year; with players from Michael van Gerwen to Simon Stevenson having hit this in multiple different events throughout the year.
Van Gerwen only has four efforts in the top 25 surprisingly; despite his ability to hit high averages a massive part of his game. This shows the depth in the
PDC though nowadays for players to hit the big averages.
