"They just came up with more plays than we did," said Singler, who had seven points in the fourth. "We just weren't able to convert and get stops. They hit a couple of big shots and they were able to win."
Tyreke Evans and Isaiah Thomas both had 15 points for the Kings (2-3), who had lost five straight to Detroit. Jason Thompson scored 13 points and Fredette had 12.
After Knight's 3-pointer and a free throw by Singler cut the Kings' lead to a basket, Marcus Thornton responded with a 3-pointer to put Sacramento ahead 100-95 with 1:134 left.
Leading by three, the Kings scored six straight to build a 90-81 advantage. Cousins had the first three points and Fredette followed with a long 3-pointer.
"I feel a lot more comfortable this year than I did as a rookie, and I think it shows," Fredette said. "I got to really enjoy the moment tonight."
Kings rookie forward Thomas Robinson hit Jonas Jerebko with a vicious elbow, knocking him to the floor early in the fourth quarter. Robinson was promptly ejected from the game.
"It was just in the heat of the game," Jerebko said. "I'm all right and it's all good. I have nothing against him. I have no problem at all."
Following a quiet first half, Evans got going in the third quarter, thanks to several twisting drives to the basket in traffic. He had 11 points in the period and the Kings took a 79-71 lead into the fourth.
The early struggles continued for Stuckey, who last season averaged 35.5 points in two games against the Kings. Stuckey opened the season shooting 1 of 23 in the first three games. He had five points against Sacramento, going 2 for 6 in 34 minutes.
Pistons coach Lawrence Frank wasn't concerned afterward about his team's offense. Detroit shot 49 percent, made eight 3-pointers and broke 100 points for the first time this season.
"Until we have a defensive mindset, it's going to be very hard for us to win," Frank said. "We have to commit. Every guy that steps on the floor has to defend. It's a simple formula, but hard to do."
Thomas scored 12 points and Cousins had 10 to help the Kings take a 55-46 lead into halftime. Led by the strong play of its bench, Sacramento outscored the Pistons 29-19 in the second quarter. Monroe had 10 first-half points for Detroit.
