Green goes through after winning final-frame decider
Former champion Graeme Dott saw off fellow Scot Jimmy Michie to qualify for the Betfred.com World Championship.
Dott, winner at the Crucible in 2006, trailed his compatriot 3-1 in the early stages of their encounter before rallying to seal a 10-5 triumph.
Stephen Lee also secured a place in the draw for the televised stages with a comfortable 10-2 result against Mike Dunn.
Meanwhile, Jamie Cope clinched a 10-5 win over Mark Joyce that included a top break of 108 and eight other runs of 50 or more.
Life was much tougher for Gerard Green, though, as he had to win a final-frame decider to get past Rory McLeod in a contest that lasted over eight hours.
However there were some big-name casualties in Tuesday's action, most notably Ricky Walden.
The 2008 Shanghai Masters champion was knocked out by Anda Zhang - nicknamed Mighty Mouse due to standing at five feet three inches tall. The 18-year-old from China clinched a 10-8 result with back-to-back centuries.
Stuart Bingham also tumbled out, suffering a 10-2 hammering at the hands of Stuart Pettman, who knocked in five half-centuries.
