Reuben Reid's brace and a late goal from substitute Zak Ansah helped Plymouth to a 3-0 win over Cheltenham at Whaddon Road.Argyle's opener arrived in the 34th minute and it was the result of a fine run from Carl McHugh. He powered through the middle and found Reuben Reid, who had time and space to beat Trevor Carson with a low finish. Chances were few and far between in the first half, but Mathieu Manset missed Cheltenham's best opportunity to level shortly before the break. He exchanged passes with Shaun Harrad and held off two defenders before firing wide with only Luke McCormick to beat. Carson made a reaction save to keep out Lewis Alessandra's shot but it was 2-0 after an hour. Reuben Reid beat Jack Deaman to make room for a shot and he saw his effort loop up off Matt Taylor and into the net. Ansah rounded off the scoring with four minutes left, nodding in Anthony O'Connor's cross.
