Wycombe back to winning ways to spoil Adam Murray's Stag party
A goal in either half secured a 2-0 win for Wycombe to ruin Adam Murray's 50th game in charge of Mansfield.
Luke O'Nein headed home from close range on eight minutes, before Aaron Amadi-Holloway wrapped up the points in injury time.
Goalkeeper Matt Ingram pulled off a number of key saves throughout as Wanderers secured their first win in five Sky Bet League 2 games.
Wycombe hit the front through O'Nein against the run of play after he found space in the box.
Craig Westcarr, Blair Adams and Reggie Lambe all wasted first-half chances for Mansfield.
Ingram saved well from Lee Collins a minute after the restart, before Sam Wood and Garry Thompson wasted good chances on the break.
Adi Yussuf tamely fired straight at Ingram, before Green shot high and wide as Mansfield wasted more chances.
The inspired Ingram then pulled off two more fine saves in the closing stages to deny Nathan Thomas.
Amadi-Holloway cooly doubled Wycombe's lead in stoppage time after a pin-point pass by Matt Bloomfield.
