Myles Peart-Harris’ second-half goal secured a 1-0 home victory for Forest Green over Cheltenham in the first-ever Sky Bet League One Gloucestershire derby.
The Brentford loanee headed in Harry Boyes’ free-kick in the 75th minute to seal Rovers’ second league win in succession.
They were on top for much of the first half, with Josh March seeing a shot deflected wide in the 12th minute after Kyle McAllister seized on a loose pass.
A high ball was not dealt with by visiting goalkeeper Luke Southwood, under pressure from Connor Wickham, but Sean Long cleared from inside the six-yard box a minute later.
Southwood parried a low drive from Peart-Harris, also keeping out Oliver Casey’s header from McAllister’s free-kick.
Peart-Harris was denied by Southwood again in the 28th minute
Cheltenham improved before half-time, with Dan Nlundulu unable to convert after Long’s throw-in.
Nlundulu then forced Casey into an error and Luke McGee had to save from Alfie May with his legs.
Josh March had a chance from a tight angle after Southwood could only push a cross into his path, but Rovers scored their deserved winner and held on comfortably.
