Cross saw off Peter Wright in a nail-biting contest in which he won 7-6 in a deciding leg. It was a close tie throughout with them both averaging around early 90's and around 40 percent on the doubles.
'Voltage' started brilliantly going into cruise control making it 3-0 with 60 percent on the doubles at this point. He began to miss darts at doubles though to go further in front.
Wright pulled it back to 3-2 behind as a result and then it became 3-3. It was parity again with a 116 checkout from 'Snakebite' keeping it interesting.
He potentially hit a crucial break of throw with a 110 checkout to make it 5-4 but Cross came back again to put it on level terms. Cross went one away to go to the brink of the final at 6-5 but a decider occurred.
From there, Cross claimed the victory to move through to a tie with 'The Iceman' in what is a tantalising prospect.
