As powerful as they've been, the San Diego Chargers in recent seasons have had trouble avoiding letdowns in games they were supposed to win.

Quarterback Dan Fouts wasn't going to let it happen again.

"We knew what we had to do," said Fouts, who tied a career mark with five touchdown passes in a 44-26 victory over the winless Baltimore Colts today.

Fouts said the Chargers had anticipated heavy blitzing from the Colts and had a plan to offset it.

Fouts had three touchdown passes to tight end Kellen Winslow and two to wide receiver Wes Chandler.

The victory extended San Diego's winning streak to five games -- the club's longest in 18 years -- and set up a final game showdown with the once-beaten Los Angeles Raiders next week.

San Diego, 6-2, and headed for the playoffs for the fourth year in a row, built up a 23-0 lead in the second quarter lead against the NFL's youngest team. The Colts fell to 0-7-1, their worst start since the club's inception in 1947.

The Colts got a 58-yard field goal from rookie Dan Miller, the third longest in NFL history.
