The Robins slipped to a fourth league defeat in a row after failing to deal with two quick-fire set-piece goals in the first half.
Two early goals in the first half just minutes apart was enough for the away side to pick up the win, despite the second-half fightback from Altrincham.
Before Bromley took the lead, it was Altrincham that had the better start in the opening exchanges, and they probably should have been a goal up.
Were it not for brilliant goalkeeping by Bromley’s Reice Charles-Cook, they would have been. He got down well to deny Jordan Hulme’s effort in the fifth minute who was clean through on goal.
Bromley did not offer much threat but found themselves in the lead in the 20th minute after a looping free-kick was headed in by defender Byron Webster. He rose up well and gave the keeper no chance.
There was a chill in the air at Moss Lane, and the Altrincham defenders certainly would’ve been left with cold feet three minutes later following yet another set-piece goal.
The goal came from a corner this time. The ball fell to Bromley’s Michael Cheek inside the box who the ball into the net after it was initially headed off the line by Eddy Jones. The 59 travelling Bromley supporters would’ve been delighted with their team’s effort going into the break.
Phil Parkinson’s men responded well and managed to get a goal back five minutes into the second half through on-loan winger Tyrese Sinclair’s close-range diving header after good work by Josh Lundstrum on the left-hand side.
The home crowd did their best to try and rally the team to an equaliser but Bromley were a tough side to break down and well-organised.
Before the match, there were touching tributes for Altrincham Legend, John King, who recently passed away.
The defeat keeps Altrincham in 14th on 36 points, just 7 points above the relegation zone with many of the teams below them having one or two games in hand.
The win for Bromley lifts them up to 8th, sitting just outside the playoffs on goal difference. Next up for Altrincham is another tough home match against third-place Woking.
