NEW ORLEANS — Derrick Rose is 31 and his body has taken a beating, but the 2011 NBA MVP showed once again he can still take over a game and knock down the decisive shot.

Rose hit a 14-foot jumper in the lane with 0.3 seconds left and scored 17 of his team-high 21 points in the fourth quarter to lift the Detroit Pistons over the skidding New Orleans Pelicans 105-103 on Monday night.

It was Rose’s second consecutive strong fourth-quarter performance for the Pistons, who have won four of five. New Orleans lost its ninth straight.

“I don’t talk or boast or brag about it, but I still have goals,” said Rose, who has endured a series of physical setbacks, including an ACL tear, that have resulted in him playing for five teams over the past five years.

“I know overall where I’m at as a player and as a person, and I believe in myself,” Rose added. “That’s where it all starts — with me believing in myself — and going to an organization and playing for a team that believes in me, too. I believe this is the start.”

With the game tied at 103, Detroit worked an isolation play for Rose, who dribbled the ball out top against Jrue Holiday, one of the best defenders in the league.

Rose drove into the lane, spun to the right and hit his jumper over Holiday’s outstretched arms.

“He has everything,” Holiday said. “I think it was a good play on his part. I’m not going to take anything from him. He’s a great player and the shot that he made was a tough shot. There was nothing I could do about it.”

Pistons coach Dwane Casey said Rose is not completely recovered from a strained right hamstring that forced him to miss five games last month. But his leg must be improving. In a 108-101 victory over Indiana on Saturday, Rose had 10 fourth-quarter points — including four in the final 1:14 and a floater in the lane with 18.4 seconds left that iced the game.
