WASHINGTON (AP) -- Maicon Santos scored his first two goals with

his new club and added an assist to lead D.C. United to a 4-1

victory over F.C. Dallas Friday night.

Nick De Leon added a goal, the second of his rookie season, and

Danny Cruz also scored as United (1-1-2) picked up their first

win of the new season.

Blas Perez scored his second goal of the year before halftime

for FC Dallas (1-1-2), which has now lost its second straight on

the road after beginning the season with a win and draw at home.

Dallas' Daniel Hernandez was sent off in the 78th minute when he

picked up his second yellow card after a rough challenge on

Dwayne De Rosario.

After reaching halftime tied 1-all, United scored three goals

during a 13-minute stretch to turn what had been a close contest

into a comfortable win.

De Leon struck in the 60th minute, controlling a perfect cross

from Santos with his first touch, and hammering a half-volley

past Dallas' Kevin Hartman with his second.

Six minutes later, De Leon got free on the left and drove a low

cross to Cruz, whose one-time effort bounced past Hartman from

close range.

Santos, who was acquired from Toronto F.C in the offseason, then

scored his second in the 73rd minute, heading in De Rosario's

cross.

Television replays appeared to show Santos in an offside

position when the ball was played.

Santos' blasted a 25-yard strike past Hartman before halftime to

give United an early 1-0 lead, before Perez struck just before

halftime after a flubbed defensive clearance.

Bill Hamid, United's usual starting goalkeeper, missed Friday's

match with a left ankle sprain suffered in the United States'

3-3 draw against El Salvador in Olympic qualifying Monday.

Joe Willis replaced Hamid, who is expected to miss one to weeks

according to a team press release, and made three crucial

first-half saves to move to 1-1-1 in three starts.
