Last year's runner-up Graeme Dott held off a fightback by Mark King to win 10-7 and clinch a second-round match against Ali Carter at the World Championships.
Dott, from Larkhall, began the session 6-3 ahead and stretched his lead to 7-3 before King started his revival with a break of 138, the highest so far in this year's championship and his Crucible best, beating the 137 he made in 2001.
King came back to trail just 7-6, but 2006 champion Dott pulled away once more to oust the Romford potter.
This afternoon also saw John Higgins return to the Crucible, 12 months after losing in the second round to Steve Davis.
After leaving Sheffield he became embroiled in a scandal which led to him receiving a six-month suspension.
Higgins was punished for breaching rules around betting, but the most serious charge of agreeing to fix frames was dropped, and he received a warm welcome today on his return to Sheffield.
The 35-year-old Scot began against Stephen Lee with perhaps a little tension in his arm. But he made three centuries in five frames after the mid-session interval - 132, 101 and 131 - and carries a 6-3 lead into Thursday's final session.
