Joeys and Scots kept their 2019 GPS premiership hopes alive with tight wins over Riverview and Kings respectively in round three.  Joeys were too strong for rivals Riverview in the second half of their grudge match at Hunters Hill scoring five tries in a 34-23 victory, while Scots scored a late try to claim a come from behind 15-14 victory over Kings.  The two undefeated schools will meet one another on the final Saturday of the competition in just under a fortnight’s time but will need to survive two potential banana skin matches in round four this weekend.  Joeys face a Kings side that’s been boosted by the return of star back Joseph Suaallii, while Scots will travel to Stanmore to face an in form Newington team who are still in the premiership hunt.  Scots’ clash against Newington on Old Boys Day at Stanmore will be particularly tight.  While Scots remain undefeated, they’ve been lucky to get the points in their past two clashes and were poor on Saturday
