The Essex 73's can close out their Schmalz Cup quarter-final series tonight in Dorchester.
The team's already outscored the Dolphins 19-2 through the first three games, including a 10-0 drubbing at home on Sunday.
With a win, Essex will go on to face either Grimsby or Ayr in the semi-final.
Last year, they beat the Ayr Centennials in five games, en route to the Schmalz Cup final.
A 73's loss tonight brings the series back to Essex for Game 5, Friday.
