Cross led 4-1 against Jamie Hughes but it went to a decider which 'Voltage' only just got through.
For him though, he knows that he can't switch off against capable players and that despite getting through to the latter stages, he believes he hasn't been sharp all week and will look forward to seeing the back of the group stage.
"I've not been sharp all through the group stage," conceded Cross, the number two seed.
"I got away with it again today, which is a blessing, but I know I've got to be much better than that. I can't keep switching off against capable players.
"Nothing has gone to plan this week, I'll be glad to see the back of that group stage and now I've got to improve on Wednesday or I'm going to lose."
