Chesterfield boss Lee Richardson was left to rue a missed opportunity after his side conceded a last-minute equaliser in their 1-1 draw at Wycombe Wanderers.
The Spireites were set to take all three points from Adams Park thanks to a Jack Lester strike, only for John-Paul Pittman to level right at the death.
Richardson said after the game: "I thought we deserved the win, in the first half we controlled the game and with a little bit of luck we would have scored more than the one.
"The second-half penalty miss meant that we didn't have that cushion and when you are playing a team that has been up the top for most of the season, they have that extra bit of belief that keeps them going.
"A bit of inexperience from some of the young lads has cost us and we got punished for giving away the free-kick at the end.
"But I can't fault the efforts of the players."
