Match ends, Bournemouth 1, Newcastle United 4.
Bournemouth's Premier League survival hopes were dealt another blow as Newcastle beat them comprehensively with an exciting performance at Vitality Stadium.
Jefferson Lerma's mistake was punished by Dwight Gayle to give Newcastle an early lead and Cherries manager Eddie Howe shook his head in frustration as Sean Longstaff made it 2-0 within half an hour.
Bournemouth hit the woodwork twice in the second half but could not recover once Miguel Almiron netted a third for Newcastle.
Substitute Valentino Lazaro made it 4-0 after he was slipped in by Jonjo Shelvey and he hit the post moments later, before Isaac Hayden skewed the rebound over from a few yards out.
Dan Gosling bundled in a consolation goal in stoppage time for Bournemouth, who now sit second-from-bottom of the Premier League with six games remaining.
Painful times continue for Cherries
Relegation now seems a matter of when and not if for Bournemouth, who desperately needed points from this game.
Manager Eddie Howe said their situation "hurt deeply" following their recent 1-0 defeat by Wolves; against Newcastle, his players looked like a team resigned to going down rather than one fighting to stay up.
Lerma's early mistake summed them up - his poor first touch invited pressure from Longstaff, who won possession back for Newcastle. From that point on, Bournemouth looked shaky, short of confidence and reluctant to play out from the back.
"The players are playing slightly tense, you could say understandably with the position they are in," Howe said afterwards. "I urged them to play the game and not the situation but they are struggling a bit under the weight of that."
Bournemouth were punished by Gayle, who showed composure in front of goal for the opener, while Saint-Maximin continued to torment the defence for the impressive hour he was on the pitch.
Howe's half-time team talk seemed - momentarily - to kick some life into his side as Dominic Solanke's deflected shot bounced off the inside of the left post but Joshua King was offside when he headed in the rebound.
Any hopes of a comeback, though, were dashed minutes later when Almiron clipped it into the top left corner to make it 3-0 to Newcastle.
David Brooks curled a shot on to the crossbar for Bournemouth, for whom it looked like being a blank evening until Gosling got on the end of Nathan Ake's header seconds before the full-time whistle.
Howe, who looked dejected throughout, walked off the pitch with his head hung low, while some of the Bournemouth players crouched down on the pitch at full-time.
The result leaves second-bottom Bournemouth fighting for their safety with six games remaining and they still have to travel to Old Trafford and Etihad Stadium, as well as welcoming Tottenham and Leicester to Vitality Stadium.
Saint-Maximin 'capable of doing anything'
Newcastle boss Steve Bruce said before the game his side had a "wonderful opportunity" to break into the Premier League's top 10 by the season's end.
His optimism has clearly rubbed off on his players as they got off to a rapid start - Gayle scoring within five minutes, setting the tone for a comfortable first-half performance.
The visitors' creativity was showcased in full by their star man Saint-Maximin, who Bruce said after the match is "capable of doing anything".
The summer signing, who picked up three assists in this match, produced the goods after half an hour when he deceived three defenders on the left and put a chance on a plate for Longstaff to fire into the roof of the net.
"I like my second assist because it is good dribbling," Saint-Maximin told Sky Sports at full-time. "I said to Longstaff to wait for this and he was to score a great goal so I am really happy."
And while Bournemouth's heads went down, Newcastle continued to play with freedom and expression - Saint-Maximin taking on defenders at any opportunity, while Shelvey's passing was full of vision and precision, and Almiron was a burst of energy when he came on.
"He has wonderful talent," added Bruce, when discussing Saint-Maximin's impact on the victory. "Every time I go to a ground and people haven't seen him play, they always say what a talent he is. He can only get better."
Newcastle will have a spring in their step after picking up three consecutive away wins for the first time since November 2016 and they now sit two points off Sheffield United in 10th place with six games remaining.
'We contributed to our own downfall' - what they said
Bournemouth boss Eddie Howe, speaking to BBC Sport: "It was another difficult start for us. The two games have been built up so much here at home [against Crystal Palace and Newcastle]. The importance of them... both times we have conceded an early goal and it has really knocked our stride and confidence.
"We contributed to our own downfall. There were some uncharacteristic mistakes. It may be a lack of confidence. It was close to being a lot better than it looked. There were some good bits mixed in there but they get lost and deservedly so with the result."
Newcastle boss Steve Bruce, speaking to BBC Sport: "Some of the football we played and the goals we scored were a delight to watch. All credit to the players.
"I felt we had lost that cutting edge, creating an opportunity to try to win a match. We enjoyed playing, that was pretty evident. There was a certain cutting edge to them. Long may it continue."
