He defeated James Wattana 10–5 in the final round of qualifying at the 2007 World Championship, to become the third-youngest player (at the time) ever to reach the main stage of the tournament (champions Stephen Hendry and Ronnie O'Sullivan had both been younger when they made their Crucible debuts). Trump is one of only five players to make their first appearance at Sheffield's Crucible Theatre at the age of 17 (along with Hendry, O'Sullivan, China's Liu Chuang and Belgium's Luca Brecel). He played the 2005 champion and sixth seed, Shaun Murphy, in the first round, but lost 6–10 despite having led 6–5 earlier in the match.
