St Vincent's were too strong for the Offaly opposition.
Birr's hopes of reaching a Senior Provincial Final came to a disappointing end at the weekend.
Dublin champions St Vincent's were too strong for the Faithful side as they secured a convincing 3-13 to 0-05 win in the semi finals of the Leinster Senior Camogie Championship in the Faithful Fields on Sunday.
The goals were scored by Aisling Maher and Niamh Hetherton who got a brace.
They will now face Dicksboro in the decider in two weeks time after their five point win over St Martin's.
Birr's season is now finished for 2023.
