McGill won the next two but a miss allowed Wilson – ranked 31 places higher – to regain some control at 5-2.
The Scotsman’s composure returned as he won the session’s final frame with a break of 92.

McGill unfazed on semi-final debut
McGill looked comfortable stepping up to the one-table set-up at the Crucible as he took the first three frames, which included breaks of 83 and 78.
Wilson – who beat defending champion Judd Trump in the quarter-finals – eventually got on the board in the best-of-33 match but McGill took control again after the mid-session break to go 4-1 up.
The Englishman’s error count increased as the pressure mounted and a break of 69 helped McGill take the sixth frame.
After a break of 45, Wilson gave McGill a chance to win the seventh but the Scotsman missed a straightforward blue to the middle and the opportunity to take a 6-1 lead.
McGill then came close to his first century break of this year’s tournament and had to settle for a 92 to end the session.
‘McGill has surprised a lot of people’ – Analysis
Six-time world champion Steve Davis on BBC Two
This is the most impressed I’ve been with Anthony McGill.
He has looked very assured. I think he has surprised a lot of people here.
I think most people thought it was Kyren Wilson’s destiny to at least get to the final… but that’s not the storyline so far. It’s not like Kyren’s really got going in the match.
We know from multi-session tournaments that it could turn around. Kyren could win the next one 6-2.
You’ve got to be strong enough from behind. If you can play decent snooker when the scoreline doesn’t look great for you – that’s the answer.
