Andre Agassi celebrated his comeback from injury with a 60th ATP title triumph as he beat Luxembourg's Gilles Muller to win the Mercedes-Benz Cup.
The 35-year-old American came into the tournament after a two-month spell on the sidelines with a sciatic nerve injury in his back.
He was rarely troubled by the unseeded Muller in Los Angeles as he cruised to a 6-4 7-5 win in just 90 minutes.
It was Agassi's first title since his victory in Cincinnati last August.
And he joins Frank Parker, Roy Emerson and Jimmy Connors as the only four-time winners of the tournament.
"It feels amazing. This is why you work so hard," said Agassi.
"This feeling doesn't happen so often any more. I'm taking it all in and feeling good.
"It's great to remember how tennis used to feel for me. I'm only thinking about my game right now, not my injury.
"My body has responded. My recovery is great and moving along well."
The top seed dominated the first set, starting with a break and losing just two points on his own serve.
He increased the pressure on Muller in the second set, breaking for a 6-5 lead before serving out for victory in the next game.
