While the home side have put together a five-match unbeaten streak, the visitors posted back-to-back wins to earn a spot in the top six.
Although there have been times this season when Newport were in contention for automatic promotion, a strong finish was required to claim a place in the playoffs.
Eleven points were collected from five fixtures, a period which included a pivotal 1-0 victory over champions Cheltenham Town.
A point at relegated Southend United earned County fifth position rather than seventh, ensuring that they avoided in-form Morecambe.
Nevertheless, despite conceding just three goals in nine matches, Michael Flynn knows that his side can ill-afford any complacency at this stage of the campaign.
Remarkably, none of this squad have scored more than six strikes all season, the team reliant on three goals in as many games from defender Mickey Demetriou during the run-in.
With 10 points being collected from their final six matches, the gamble has paid off thus far, and Ball will be increasingly confident of achieving an unlikely promotion.
Forest Green's three victories since Ball's appointment have been through strong second-half performances, the last outing against Oldham Athletic seeing three goals netted after the hour mark.
At a time when just three strikes have been conceded in five encounters, the signs are there that Rovers are peaking at the right time as they bid to move into League One for the first time in their history.
Aaron Collins has contributed three goals and an assist during his last two appearances, match-winning performances after going 11 fixtures without finding the back of the net.
Having avoided defeat since April 20, Flynn is expected to keep changes to his Newport side down to a minimum.
Matthew Dolan, County's joint top goalscorer, is an option in a three-man backline, but preference is likely to be given to the trio which started against Southend.
Forest Green will have to make do without Ebou Adams after the midfielder was dismissed for two yellow cards against Tranmere Rovers.
Newport County possible starting lineup:
King; Shephard, Bennett, Demetriou; Lewis, Labadie, Sheehan, Hartigan, Haynes; Collins, Amond
Forest Green Rovers possible starting lineup:
McGee; Godwin-Malife, Stokes, Cargill; Wilson, Moore-Taylor, Hutchinson, Collins; Davison, Wagstaff
We say: Newport County 2-1 Forest Green Rovers
Both teams will feel that they have momentum heading into this fixture, something which should lead to a quality contest playing out in South Wales. While the visitors would be satisfied with a share of the spoils, we are backing the home side to edge this fixture by the odd goal in three.
