Substitute Kaid Mohamed netted the winner as Cheltenham came from behind to beat Plymouth.
The visitors broke the deadlock on the half-hour mark when Conor Hourihane nestled a fine shot into the bottom corner of the net.
But their lead only lasted for seven minutes as Steve Elliott headed in a Billy Jones free-kick.
Plymouth had a penalty appeal waved away before Jones set up Mohamed, who nodded in his third of the season.
VIEWS FROM THE DRESSING ROOM
Cheltenham Town manager Mark Yates told BBC Gloucestershire:
"I thought we were outstanding, especially in the first half.
"We earned out luck at the end when Scott Brown made a fantastic save.
"Chris Zebroski was outstanding but he was guilty of missing three or four chances.
"But we'll take that because he's a proper lad and put in a proper shift."
