Andre Agassi clinched the 60th title of his career by beating Gilles Muller of Luxembourg 6-4, 7-5 in the final of the Los Angeles Open on Sunday.
The top-seeded American, still a major force in the game at the age of 35, put paid to his 22-year-old opponent in a little under 90 minutes.
Agassi's triumph, his first of the season, put him level with Frank Parker, Roy Emerson and Jimmy Connors as the only four-time winners of the tournament.
The eight-times grand slam champion improved his Los Angeles record to 34-6 by avenging his loss to Muller in their only previous match last August in the Washington semi-finals.
"It feels amazing," said Agassi. "This is why you work so hard. This feeling doesn't happen so often any more. I'm taking it all in and feeling good."
Agassi, playing again after two months out with a sciatic nerve injury in his back, dominated the first set after 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.
"It feels good to let my game fly, have the eagerness to scamper for balls not sure you will get to and end up winning the points," added Agassi, who is listed as an entry for next week's Washington event.
"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."
Agassi became the fourth ATP winner aged above 30 this season after Australian Wayne Arthurs, Denmark's Kenneth Carlsen and Briton Greg Rusedski.
