TAMPA, Fla. (AP) _ Mamadou Diallo had his second consecutive two-goal game as the Tampa Bay Mutiny remained undefeated at home with a 3-1 victory over the Columbus Crew on Saturday.

The Mutiny's 6-0 start at Raymond James Stadium is two behind D.C. United's MLS record of eight consecutive home victories to start the 1998 season. Dominic Kinnear scored his first goal since Aug. 29, 1998, in the 48th minute, and Carlos Valderrama had two assists for the Central Division-leading Mutiny (6-4-0).

Valderrama has 10 assists for Tampa Bay, which has outscored opponents 20-5 at home.

Robert Warzycha scored on a 74th-minute free kick for Columbus (3-6-1), which lost for the second time this season at Tampa Bay. The Crew dropped a season-opening 5-1 decision to the Mutiny on March 18.

The Crew are last in the Central, eight points behind Tampa Bay.

Tampa Bay coach Tim Hankinson, who uses a 4-5-1 system, opted to start Diallo over Raul Diaz Arce as the lone forward. The decision paid off 11 minutes in when Diallo scored from 10 yards.

A minute later, Mutiny midfielder Steve Ralston left with a right leg injury. After being examined on the sideline, Ralston left the field on crutches.

Diallo beat two defenders to a pass from Valderrama in the 38th minute to score his seventh goal of the season, giving the Mutiny a 2-0 lead.
