Judd Trump survived a test of nerve on a day his form deserted him to edge through to the second round of the World Championship.

Runner-up to John Higgins in Sheffield in 2011, Trump was well beaten in the semi-finals by Ronnie O'Sullivan last year and has endured a distinctly mediocre 2013-14 season, with a run to the German Masters final his best achievement by far.

The Crucible finale presented Trump with a chance to put it all right, but the 24-year-old was drastically out of sorts in the second session of his clash with Tom Ford, seeing a 6-2 overnight lead reined in. Leicester-based qualifier Ford got back to 8-8, and another major shock, after the early defeats for Ding Junhui and John Higgins, was in the offing.

But with his tournament hanging in the balance, Trump dug deep and ground out two attritional frames to win 10-8 and set up a second-round clash with Ryan Day.

Trump said he felt “relief” at reaching the last 16, admitting: “Every time I got in I didn’t feel comfortable.”

But he added: “It doesn’t matter how you play if you become world champion.”
