Jermain Defoe fired Bournemouth to their first win of the Premier League season to relieve mounting pressure on boss Eddie Howe.
The 34-year-old rifled his first Bournemouth goal in 16 years, as the Cherries came from behind to sink visitors Brighton 2-1.
Solly March's header had Brighton dreaming of a second successive Premier League win but Andrew Surman coolly levelled before England poacher Defoe stole the victory.
Defoe last scored for Bournemouth on a loan spell in May 2001, and the veteran exhibited all his stunning staying power to settle this south coast derby.
