Part on Van Barneveld's second round performance against Cross: "He didn't handle the adversity very well when it started going against him"
Part spoke after his defeat to 'Voltage' and said that it became difficult when he was in the firing line and on the back foot.
"He didn't handle the adversity very well when it started going against him. He's not too used to these situations anymore - it's been a while. It's hard for him to step back into the assault if you will, and have things go wrong," said Part to Sky Sports.
"Maybe Raymond wasn't the best necessarily in those situations. Certainly, he's come through a few and I'm not criticising him, but the way Rob came back at him, it was a brilliant display by Rob Cross. Probably the best 90 average match he's ever had. The most important one as well.
"To fight back and assert himself, his celebrations along the way were really physical and he really just stamped his authority on it. Raymond seemed to buy a little bit into that unfortunately for him."
