O’Rourke won the opening tip, but the rest of the score belonged to O’Sullivan.
He got a great second to Togher Cross, which O’Rourke took two to beat. He held close to a bowl in the next few shots and raised a full bowl with his sixth to the creamery.
He had almost two bowls at Shanacrane cross.
He had almost three bowls before the line. He plays Patrick O’Donoghue in Sunday’s Munster final at Templemartin.
European champion Carmel Ryan qualified for the Munster senior final when she beat Geraldine Daly at Béal na mBláth on Monday.
Daly won the first two tips, Ryan took the next two and increased her lead with a good fifth. Daly cut the odds to less than a metre with her next two and they were level to Shorten’s cross. Ryan edged the next three to Long’s lane. She was 70m fore at Twohig’s farm, but Daly clipped it to 40m.
Ryan finished the stronger though, and pushed her lead to a bowl.
In the final she plays Triona O’Farrell-Kidney, who beat Juliet Murphy.

Both Munster intermediate semi-finals will be played on Saturday. Last year’s beaten finalist Donal Riordan plays Raymond Ryan at Caheragh and Trevor O’Meara faces Andrew O’Leary at Gortroe, Mallow.
Ryan bowled brilliantly at Templemichael to beat PJ Cooney by almost three bowls.
He beat a big opening bowl from Cooney and increased his lead with his second. He had almost a bowl after lofting his third and he raised it with a great fifth to Murphy’s wall.
He got three blistering bowls on the straight to increase his lead to two bowls. He was three in front at the novice line, but Cooney knocked the third bowl before the line.
Donal Riordan also had a line-to-line win over David Hubbard at Baile Mhuirne.
Trevor O’Meara beat Michael Bohane by almost a bowl at Clondrohid.
He won the opening tip with a good bowl to Macroom Mills. Bohane took the second, but O’Meara edged the third shots past the mulch yard. He was still in front at Tirbeg cross and increased his lead to Kelleher’s farm. Bohane regained the lead with a good bowl towards the Bell Inn.
O’Meara won the following exchange and increased his lead with a good bowl to just short of light a Goff’s lane. Bohane regained the lead, but O’Meara pushed clear with a good bowl towards O’Callaghan’s. Bohane missed light with his next and when O’Meara went out he had almost a bowl and the score was effectively over.
Andrew O’Leary beat Johnny O’Driscoll at Béal na mBláth.
O’Driscoll won the first three shots and increased his lead to 100m after six to Shorten’s cross. O’Leary levelled with a great seventh but O’Driscoll pushed clear again to Long’s lane. He had almost a bowl at Twohig’s farm and raised it at the garage.
He followed with three poor shots to lose the lead. He regained the lead with a great 15th, but O’Leary got an equally good 16th to go back in front. O’Leary had just five metres with three to go, but he increased his odds with his next two and won comfortably with his last shot.
