Hearts of Oak increased BA United's woes with a 2-0 victory at the Accra Sports Stadium on Saturday.
Striker Gilbert Fiamenyo scored a brace to give Herbert Addo's side all the three points in the First Capital Plus Premier League Week 11 match.
Fiamenyo who has scored eight goals so far this season got the opener in 37th minute with a header.
The Phobians who felt comfortable throughout the game missed clear opportunities to increase their lead.
With just about five minutes to full-time, Isaac Oduro's freekick found Fiamenyo again as he headed home the second goal for the Phobians.
The result gives Hearts of Oak a boost as they prepare to travel to Senegal next weekend for their CAF Confederation Cup second Leg match against Olympique de Ngor.
Hearts of Oak won 2-1 in the first leg which was played at the Accra Stadium last week.
