Jeremy Bell missed a shot in the final seconds as Plymouth Raiders lost their first BBL Championship match of the season, 77-76 at Worcester Wolves.
Plymouth, who were behind for much of the first half and trailed by seven points going into the final quarter, took a 76-75 lead with 18 seconds left.
But Sherrad Prezzie-Blue gave Worcester the victory with a late basket to leave the Wolves unbeaten after four matches.
Bell top-scored for Plymouth with 24 while skipper Anthony Rowe hit 18.
Wolves, who are now joint-second, had beaten Mersey Tigers on Friday, 97-79.
