British light-heavyweight Buatsi secured a victory yet underwhelming beginning to life under recent management with a decision win over Parker in the Manchester arena.
The Olympic bronze medallist's work rate likely gained him a majority decision in a competitive 10-round bout at the Manchester venue.
But the challenger landed significant shots, landing some telling clean blows in a contest where the approaches never quite clicked, with excessive holding marring the fight.
The officials had it 96-94 to the winner, with the final judge a even score.
"It wasn't my best display but what defines champions? They prevail," Buatsi stated in the ringside as he was greeted with boos from the crowd.
The Londoner bounced back after his initial pro loss - an epic battle with his previous opponent in last winter - to claim a 20th pro success.
Some ringside observers believed Parker, 31, merited the win but the contender endured the second setback of his 28-match career.
The fighter's advancement has slowed in recent years through management issues and extended periods of inactivity.
Previously predicted as the rising talent of UK boxing, he now stands trying to realize his potential - maybe in what feels like a last chance - under recent support.
He opened tentatively, with both competitors willing to overcommit in a calculated initial rounds.
Parker, whose sole prior loss came at super-middleweight against his former opponent in two years ago after breaking his hand in the contest, was competing in only his second bout at light-heavyweight.
By the fight's midpoint, the underdog had stayed in contention, creating difficulties for the favorite, who utilized a tight guard to narrowly win the more effective periods.
The crowd's patience decreased during constant clinching, with Parker falling to the floor various instances during clinches.
Parker finished the stronger, but many rounds were hard to judge. Nevertheless, previous titleholder the boxing analyst - providing analysis for Dazn - had it significantly in favor for the challenger, awarding Buatsi just only one stanza.
The victor progresses, but with the likes of power puncher David Benavidez, and Russian champion Bivol leading the category, the path to championship success - judging by this showing - still seems difficult.
In the secondary fight, Lyndon Arthur defeated Rea by divided decision in a terrific all-Manchester battle to win the continental belt.
The stadium became quiet for a deeply poignant memorial ahead of the contest as ten bells sounded in honor of the city's native Ricky Hatton, who passed away aged 46 in September.
It was the premier televised match card in the city since the passing of Hatton. As the concluding sound faded, the stillness became a roar of "there's only one Hatton".
The action inside the ropes equaled the sentiment. The eventual winner was floored by a significant blow flush on the chin in the early round, getting up unsteadily to his feet on the referee's count.
But the traditional red shorts of the fighter soon came forward again. From the other corner, the opponent - in competitive blue - was damaged soon, significant bruising appearing under his face as the fighters landed hard punches.
The challenger, twenty-seven, landed power punches but the champion, thirty-four, matched the intensity with effective uppercuts as the action rarely dropped over 12 rounds.
Arthur edged the decision with scoring tallies of 114-114, 115-113 and 115-112, but each competitor were persistent and brave, exactly what their idol Hatton represented.
