The Reds took the lead through new signing Daniel Sturridge in the 7th minute who calmly finished past Mansfield custodian Marriott after Jonjo Shelvey had set him free with a brilliant through pass.
Despite playing their football in the Conference National, Mansfield showed no signs of fear against the Premier League outfit and pushed on for an equaliser, coming close a few times and keeping Liverpool goalkeeper Brad Jones busy throughout the game.
Liverpool however doubled their advantage in the second half against the run of play, with Luis Suarez bundling his shot over the line after clearly controlling the ball with his right arm following a rebound from his initial shot which was saved by Marriott.
The Stags managed to pull one back in the 79th minute through Matthew Green, but it was too little, too late as Liverpool eventually booked a fourth round meeting with Oldham Athletic.
Here, ESPNSTAR.com takes a look at the players who took to the One Call Stadium.
Alan Marriott - 7
Marriott was on hand to make several good stops early in the first half and showed great awareness to rush out of his area quickly to clear the danger on several occasions.
John Thompson - 6
The former Nottingham Forest player was often caught out of position by the mobile Sturridge during the initial stages of the game but he slowly grew into the game and made a few good tackles.
Exodus Geohaghon - 7
Geohaghon's devastatingly powerful long throws caused all sorts of havoc in the Liverpool defence and he almost got himself on the scoresheet with an accurate header in the second half.
John Dempster - 7
Dempster looked comfortable on the ball in defence and launched a few good counter-attacks from the back with his accurate distribution of the ball.
Lee Beevers - 7.5
Beevers defended heroically for his team, putting his body on the line and blocking several dangerous looking shots. He also proved a handful for the Liverpool defence during set-pieces and had a few decent opportunities to hit the back of the net.
Chris Clements (82' off) - 7
It was not the most technically proficient display by Clements, but he more than made up for it with a performance full of energy and grit. The 22-year-old worked tirelessly in midfield and won his fair share of tackles to stop Liverpool's midfield from getting a real foothold in the game.
Adam Murray - 7
Murray's tenacity in the middle of the pitch ensured the Reds' midfielders barely had anytime on the ball. He showed great strength to outmuscle Allen and Lucas off the ball on numerous occasions and he will be pleased with his overall contribution to the game.
Anthony Howell - 7.5
Howell did very well in the middle of the pitch to be the conduit for Mansfield's transition from defence into attack. He won and recycled possession effectively, spreading the ball well and stretching the Liverpool defence with his pinpoint passes.
Louis Briscoe (64' off) - 8
Briscoe partnered Green very well up in attack and held the ball up very well on his own whenever he had it. He created several good goalscoring chances for his team-mates and came close to scoring a few times.
Matthew Green - 8.5
Green was undoubtedly Mansfield's greatest attacking threat throughout the game. The 26-year-old's clever off-the-ball running often saw him easily evade the attentions of Coates to get into great goalscoring positions. His finishing left a little to be desired at times, but his goal was no less than he deserved for a fantastic display up front.
Lindon Meikle - 8
It was an enterprising display in attack by Meikle, whose pace and direct running had the Liverpool defence on the back foot most of the time. His link-up play with Green was particularly pleasing on the eye.
Colin Daniel (64' on) - 7
Daniel came on to provide an added attacking thrust for Mansfield and got himself involved in several good passages of play.
Matthew Rhead (82' on) - N/A
Brad Jones - 8
Jones probably believed he would have an easy day against unfancied Mansfield but the Stags gave him a real workout in goal as the 30-year-old custodian had to make save after save to keep his side from conceding. Only poor play from his defenders allowed Green to score against him.
Andre Wisdom (78' off) - 7
It was a stable, if unspectacular, shift on the right flank from the 19-year-old, who showed a pleasing willingness to bombard forward to support his attack throughout the game. He needs to brush up on his defensive work for future games though.
Jack Robinson - 6.5
Robinson did reasonably well at left-back in the first-half but made several errors in the second period of the game, including what proved to be an almost costly slip which allowed Briscoe to get his shot away but thankfully for the 19-year-old, Jones made the save to spare his blushes..
Jamie Carragher - 8.5
So often the leader at the back for Liverpool, Carragher has found himself on the fringes of the first-team in recent times owing to his advanced years and the potent partnership between Daniel Agger and Martin Skrtel, but the one-club man gave a reminder of why he was once regarded as one of the best defenders in the world with a super performance at the back.
The 34-year-old, captain for the day, led the Reds by example, making numerous important interceptions, sliding in bravely to block any shots on goal and showing great timing of the tackle to dispossess the effervescent Green on a few occasions.
Sebastian Coates - 6
Coates will have to do a lot better if he wants to convince manager Brendan Rodgers that he deserves a place in the first team. The Uruguayan was unconvincing in defence and gave away possession too cheaply.
Lucas Leiva - 6.5
It is clear Lucas has still not gotten back to full fitness following his long injury lay-off. The Brazilian looked laboured in the middle of the pitch and failed to properly cope with the energetic Mandfield players.
Joe Allen - 6.5
Allen was one of Liverpool's brightest stars at the start of the season, but it would be fair to say his star has faded somewhat in recent times. And the former Swansea player did nothing to dispel the notion that he was currently off-form with more than a few misplaced passes and mistimed challenges.
Jonjo Shelvey - 7.5
Shelvey looked lively in the first half and seemed to work well with Sturridge in attack. He created numerous good goalscoring chances for Sturridge during the game and was the catalyst for Liverpool's first goal, threading a brilliant through ball for Liverpool's new signing to score.
Suso (55' off) - 6
Quite why Suso has been unable to recapture his early season form is a mystery. The young Spaniard is without question one of the most technically proficient players for Liverpool but he has not been able to produce on a regular basis, and Rodgers seems to be quickly losing faith in him.
Stewart Downing - 7
Downing provided some pace and incision in attack for Liverpool down the right flank but his final ball was often poor. The former Aston Villa player also did well to curb his attacking instincts to help out in defence when his side were under pressure.
Daniel Sturridge (55' off) - 8
It was the ideal debut for Sturridge, who scored with a calm and composed finish in the 7th minute to put Liverpool in the lead. He looked really sprightly in the time he was on the pitch and could have bagged himself a hat-trick but for the heroics of Marriott.
Jordan Henderson (55' on) - 5
Henderson barely touched the ball and failed to make any sort of impact for Liverpool when he came on.
Luis Suarez (55' on) - 7.5
So often the hero for Liverpool, Suarez proved his invaluable worth to the club once again by scoring the winning goal, albeit in controversial circumstances. The former Ajax player's tricky feet helped earn his side a few crucial free-kicks in the advanced third of the pitch to help ease the immense pressure which the Reds' defence were subjected to in the second half.
John Flanagan (78' on) - N/A
