Angus Kilkolly, Ryan Tinsley and Saul Halpin form the spearhead that has yielded 15, 14 and 13 goals each respectively in the pursuit of the golden boot title race in the Rovers' awe-inspiring 63-goal haul this season.
The league leaders, who have conceded just a dozen goals in 13 matches, have established an eight-point lead over second-placed Western Suburbs who will be hosting them in the cup quarter-finals on August 19 or 20.
On the flip side, the Paul Ifill-coached Wairarapa have had, at best, a yo-yo season.
Although they are perched in third position on 27 points, one behind coach Declan Edge's troops, their league dreams this winter have evaporated but swearing by smart footy remains their incentive to find a modicum of respectability in a mediocre season.
To put the yo-yo assertion in perspective, today's hosts are coming off a 7-2 flogging at the hands of Western Suburbs in a fourth-round cup defeat and a 5-1 lesson from Wellington's comeback kids, Stop Out within a fortnight.
On Tuesday, though, Wairarapa kept their fans guessing with a 6-2 victory over Palmerston North Marist, who are no mugs, in a catch-up game in Masterton.
"We beat them 5-2 earlier in the season [in Napier]," says Robertson who is out today as a player after hobbling off the park early in last Sunday's historic 10-0 humiliation of Wellington Olympic at Park Island.
The player/coach instead opts for a circumspect "we're solid" in keeping with the season's mantra of enhancing an attacking mode of play and offering them a freedom to express themselves.
"Our hard work, training and continuity are coming to fruition now," he says, stressing striker Stephen Hoyle also has nine goals after his five-goal blitz against the Greeks.
The ability of many to find the net from anywhere along the depth and width of the park, as well as defenders cashing in from set-piece play, pleases him.
Some players have boosted their goal tally from penalty kicks more than others but it requires a certain level of dexterity and mental tenacity to convert from the spot.
"There's a bit of banter there on who'll score the most goals but the lads have adopted a professional culture so they'll feed the ball to whoever is in the best position to score.
"The team comes first and winning is the top priority."
Midfielder Tom Biss returns from injury while Finlay Milne is back in defence after serving a two-yellow card match suspension. Hoyle is in England for a fortnight.
The Rovers' ascendancy, on the heels of a 7-0 halftime result against the Greeks, means Robertson is mindful opposition, such as Wairarapa, will want nothing more to catch them on the hop to savour their season.
"I said to my boys at halftime that they needed to be ruthless and not lift their foot off the gas and to begin the second half applying the same pressure because we have some big games to come so the standard needs to be very high."
He is aware Wairarapa have added two Americans to their squad.
For the record, it's the first time the Blues are playing on today's relatively new park.
