The McDonald's Men's Premier Cricket top six could be settled a round ahead of schedule if a host of games starting this weekend stick to form.
Sydney Uni (66 points), Sydney (63) are guaranteed finals berths with two rounds to go, while Manly-Warringah (52), Fairfield-Liverpool (51) and Northern District (50) looked relatively comfortable.
That leaves sixth-placed Eastern Suburbs (40) vulnerable to a pack of chasers just outside the top six.
St George (39) head that group from Gordon (38), UTS North Sydney (34), Randwick-Petersham (34) and Bankstown (34).
The Fairfield-Liverpool v Easts two-dayer starting Saturday, along with NDs' clash with St George, loom as the round's crunch matches.
Victories to Easts and NDs will all but ensure the six play-off spots are settled with a round still to play.
The Dolphins' destiny is their own hands.
"Obviously this is a massive game for us as we look to keep our spot in the top six," Easts skipper Jack Preddey said.
"There are plenty of good sides right on our tail so we know how crucial a win is.
"All the guys are fired up after a tight win last weekend and ready to go."
Saints skipper Nick Stapleton said of his team's challenge: "It's really important we back up that performance against Uni with another good performance against NDs.
"Every week from here is do or die for us."
At the bottom of the table, Blacktown has just two games to avoid the wooden soon.
The Mounties take on Penrith at Joe McAleer Reserve.
Blacktown captain Harmon Sandhu said: "We've not given up. There is still plenty to play for over the next two games."
