Career
He is Stephen Hendry"s nephew. Cahill turned professional in 2013 after winning the 2013 EBSA European Under-21 Snooker Championships and gained a two-year tour card for the 2013/14 and 2014/15 snooker seasons. Debut season
2014/2015 season
Cahill"s second season saw him improve his game as he twice reached the last 32 in the minor-ranking European Tour events.
The 18-year-old then went on his best ever run in a ranking event during the 2014 United Kingdom Championship.
Cahill responded by taking the deciding frame to record the biggest victory of his career to date. In the last 16 Cahill said he couldn"t believe how badly he had played after his tournament ended with a 6–2 loss to Mark Davis.
Cahill would have a poor end to the season as he lost seven out of eight matches after this which would have relegated him from the tour as he finished 85th in the world rankings.
