TAMPA, Fla. (AP) _ Mamadou Diallo scored his third goal of the game in overtime as the Tampa Bay Mutiny beat the New York-New Jersey MetroStars 4-3 on Wednesday night.

Diallo, who has an MLS-best 22 goals after his first career hat trick, scored from close range with just over four minutes left in the second overtime. He is fifth player in league history _ and the first since Stern John in 1998 _ to reach 20 goals in a season.

New York-New Jersey's Alex Comas had tied in the 85th minute with his second goal of the game.

Steve Ralston put the Mutiny up 3-2 in the 70th minute.

New York-New Jersey took a 2-0 first-half lead on goals by Comas in the 21st minute and Adolfo Valencia in the 43rd. Diallo tied it with goals in the 45th and 61st.

Valencia, who has a team-best 14 goals, has scored three times in the past two games.

MetroStars goalkeeper Mike Ammann left the game with 2-3 fractured ribs and a possible broken jaw in the 29th minute. Ammann dived to beat Diallo to a loose ball. As Diallo attempted to jump over the goalkeeper, his right foot landed on Ammann's head.

Ammann was taken to St. Joseph's Hospital for X-rays.

The MetroStars were without midfielders Roy Myers (Costa Rica) and Tab Ramos (United States) because of national team commitments.
