DREW Harper scored a first half hat-trick as top of the table Stourbridge grabbed all five points in an exciting game at Paton Field.
Stourbridge were deserved winners but will know they were in a game as Caldy caused the visitors some problems in the second half.
Rich Vasey got the scoring started with a penalty after three minutes which was cancelled out by Caolan Ryan some five minutes later.
Stourbridge were dominant at the set piece with a well organised tight five and it was after some pressure at a scrum five metres out that Drew Harper got his first of the day.
Rich Vasey hit back for Caldy with a penalty kick but Harper extended the Stourbridge lead with another try from close range.
Winger Baker was on the end of a good Stourbridge move to get their third out wide, which Ryan converted.
Harper got his hat-trick before half time as he powered over to leave the half time score 25-6.
Caldy had obviously had a rocket at half time as they came out firing in the second half and took the game to Stourbridge and were unlucky not break through early on.
It took until the 58th minute for Ben Eaves to cross the whitewash after a well worked backs move.
Caolan Ryan kicked a penalty to increase the Stourbridge lead on 66 minutes.
Pete Doolan felt he had scored a try near the end but referee Rawson failed to see it. On 73 minutes, back rower Rodley was sent off for foul play.
