This showed with a 10-3 win for Cross against 'The Polish Eagle' who some would of been predicting could of pulled off a shock over 'Voltage'.
Cross though averaged 103.8 average, four 180's and 62.5% on the doubles to show a return to form for the current World Champion. He will be second favourite now. This is backed up with his average only just below that set of Anderson earlier on tonight.
It is the seventh TV tournament in a row for Cross that he has made the Quarter-Finals or better showing his remarkable rise.
