Instead of entering the All-Star break with another road victory and a healthy winning streak, the Wizards watched a second half lead vanish because their offense disappeared.

Washington went the opening six minutes of the fourth quarter without a field goal and never could stop Detroit guard Jose Calderon from making 3-point field goals, falling on the road 96-85 to the Pistons on Wednesday.

Emeka Okafor had 20 points and nine rebounds, and John Wall finished with 16 points and nine assists for the Wizards (15-36), who went from having the NBA's second longest winning streak to being outscored 31-17 in the fourth quarter.

Washington had won four straight including Monday's victory at Milwaukee and appeared in good position for another by shooting 54.5 percent from the field through three quarters. Leading by eight in the third and 70-65 after Trevor Ariza sank two free throws starting the fourth, Washington did not score again until Nene's layup with 6:06 remaining.

At this point Detroit (21-33) only led 74-70, but the trend was headed the wrong thanks to careless ball handling. Several of Washington 17 turnovers came late in middle of the second half and the Wizards shot 26.7 percent (4 of 15) in the quarter.

Tied at 76, the Pistons went on a 11-0 run with a Calderon 3-pointer in the spurt. Acquired this month in as part of the Rudy Gay trade, Calderon made 6 of 9 from beyond the arc and finished with 24 points. Will Bynum scored 20 and Greg Monroe had 16 points and 18 rebounds for the Pistons, who have all three games this season and five straight overall against Washington.
