O'Donnell showed signs of promise on his first season on the main tour in 2012/13. He qualified for the final stages of the German Masters before losing to Mark Williams in Berlin. O'Donnell's best run came in the European Tour event in Scotland as he beat the likes of Kurt Maflin and Craig Steadman to reach the quarter-finals before losing to Andrew Higginson.
O'Donnell gained a place on the main tour for the first time by coming through Q School in 2012. He beat Adrian Ridley 4-1 in the final round of the first event.
"It was a relief to win," said the player nicknamed 'The MOD', who qualified for Q School by winning the Snookerbacker Classic. "When you get to the final round you just want to get the job done, it would have been tough to go back to round one.
"It hasn't sunk in yet, but it has been my dream to play on the main tour since I was 12 years old. It has taken me longer than I had hoped, but I have got a crack at it now for two years. I'm under no false pretences about how tough it will be, but I believe I have a strong all-round game and I am good enough for the tour."
O'Donnell, who used to be resident pro at the RAC Club in London, added: "I will need to hit the ground running and to improve in every aspect. It's tough to get on the tour and probably twice as tough to stay on. I have practised with Martin Gould for 11 years and what he has done is an inspiration. He went from nowhere to being a top 16 player in four or five years and that shows it can be done."
