Trailing 4-3 entering the bottom of the eighth, Boston scored four times off reliever Vinnie Pestano (1-1) to open the largest lead in a game that featured plenty of chances at the plate but little success for either club.
And, although Lennard failed with the kick, Tonga'uiha stepped up the plate in stoppage time to add the drop-goal that stretched his side's lead to 11-0.
