CHESTER, Pa. — The good news:

The Red Bulls kept their Supporters Shield hopes alive with a road win at the Philadelphia Union.

The bad news:

So did Atlanta United.

The Red Bulls secured a 1-0 victory at TalenEnergy Stadium Sunday behind Kaku’s second-half penalty kick.

Second-place New York (21-7-5, 68) points stayed within a point of Atlanta (21-6-6, 69), 2-1 home winners over the Chicago Fire, in the Eastern Conference with one game remaining in the regular season for both teams.

The Red Bulls host Orlando City SC at Red Bull Arena next Sunday, while Atlanta visits 2017 MLS Cup champion Toronto FC. Fourth-place Philadelphia (50) fell to 15-13-5.

Kaku broke the deadlock in the 69th minute. After a review, the Video Assistant Referee ruled that Haris Medunjanin handled the ball on a Red Bulls’ corner kick.
