BOSTON (AP) -- Allison Kemp scored her first goal of the season in the 90th minute as the Boston Breakers tied the Philadelphia Charge 1-1 on Saturday night.

Kemp, who came in as a substitute in the 84th minute, gave Boston (4-8-7) the tie on a breakaway.

Liu Ailing scored for the first-place Charge (10-2-5) in the 84th minute.

Kristine Lilly and Ragnhild Gulbrandsen pushed the ball ahead to Kemp, who broke free from the Charge defense and beat Melissa Moore, the league's top goalie, with a soft tap to the far left corner.

Breakers defender Jena Kluegel passed back to goalkeeper Tracy Ducar, who tried to clear the ball but kicked it to Ailing, who was waiting 10 feet outside the box and blasted a hard shot into the net.

The Charge's Marinette Pichon, leading the league with 13 goals and 27 points, sat out with a toe injury.

The Breakers stayed unbeaten at home at 4-0-4, but were eliminated from playoff contention.
