Jimmy Butler scored 18 points and Joakim Noah added nine rebounds and 10 assists as the Bulls won for the fourth time in five games. Chicago pulled ahead of Toronto for third place in the Eastern Conference after the Raptors' loss to Brooklyn.
Gasol secured the double-double - and the win - with 5.7 seconds to play when he had a tip-dunk of Taj Gibson's miss and got fouled by Andre Drummond. Gasol hit the free throw, giving Chicago a four-point lead.
Reggie Jackson had 22 points and nine assists for Detroit, while Andre Drummond had 14 points, 22 rebounds and six blocks. The Pistons had won five of seven.
