Colin Calderwood's side took to the field for their first competitive game of the season bolstered by the addition of Oyvind Leonhardsen, Tim Sherwood and Chris Perry to the ranks.
The second string started the game in a 4-4-2 formation with Gavin Kelly taking his place in goal with, from right to left across the back, Maurizio Consorti, Paul O'Donoghue, Perry and Johnnie Jackson.
Leonhardsen started in right midfield with Sherwood, Piercy and Matthew Etherington completed the quartet, while Yannick Kamaman and Steven Ferguson accepted striking duties.
Forest sent out a strong team packed with first team experience. Familiar faces include Riccardo Schimica, David Johnson and Jack Lester.
Both teams set a high tempo from the kick-off, with Etherington lively down the left. It was from two of his crosses that Sherwood and O'Donogue went close with headers. Ferguson spurned the best opportunity of the early stages, shooting straight at Pascal Formann after bursting through down the right.
The game entered something of a lull as the first half progressed, with both teams cancelling out each other's attacking intentions. It was Spurs who got the welcome breakthrough on 40 minutes when Piercy weaved his way towards the Forest penalty area. The midfielder fed Ferguson who did the rest with a cool finish beyond Formann.
Half-time Spurs 1-0 Forest
Both teams began the second half brightly, as the contest remained, bar the scoreline, relatively even. A further plus point was the way Perry and his junior sidekick O'Donoghue coped with the expensively assembled strikeforce of Johnson and Lester.
George Snee replaced Ferguson on 68 minutes, adding a new dimension to our attacking options. Snee is a player of some trickery and very clever feet. Shortly after his arrival on the pitch, Leonhardsen fashioned a chance from the right, but overplayed the effort and lofted over from an angle.
Piercy was the victim of a heavy challenge from Forest's Gary Jones on 75 minutes and only after prolonged treatment was he able to continue, with Ben Bowditch poised to replace him. Young Ben did not have to wait long, Piercy lasted only a further three minutes before coming off.
Snee worked himself an opening as the boys appeared to grab the ascendency, but his effort was saved by Formann. Forest launched a late salvo in an attempt to snatch a point, but the boys held firm and banked all three for themselves.
Team: Kelly, Consorti, Jackson, Piercy (Bowditch 78), Perry, O'Donoghue, Leonhardsen, Sherwood, Ferguson (Snee 68), Kamanan, Etherington. Subs: Henry, Burch, Herron, Snee, Bowditch.
Steven Ferguson scored the goal that opened the reserve side's points account for the season with the full three against Nottingham Forest at Stevenage on Tuesday evening. The pacy Scot scored the decisive goal after 40 minutes of an impressive display against a strong Forest team.
