Leaders Plymouth extended their unbeaten run in Sky Bet League Two to 10 games as Sonny Bradley's double secured a 2-1 victory at Stevenage.
Argyle edged a cagey first half and almost scored on 43 minutes as Jimmy Spencer's looped effort hit the woodwork after Graham Carey had broken from midfield.
Derek Adams' visitors broke the deadlock soon after the restart when David Fox's free-kick evaded everyone apart from Bradley, who diverted the ball into the top corner.
Stevenage equalised just seven minutes later as Henry Cowans' low free-kick found Matthew Godden unmarked and he smashed the ball home from six yards.
Boro - who have now lost three of their last four league games - were only level for four minutes as Bradley glanced in a header from Carey's free-kick.
Stevenage had their chances to level during five minutes of injury time, with Jack King and Harry McKirdy going close, but Plymouth saw the game out to remain top of the table by five points.
