Andre Agassi made light work of Juan Ignacio Chela at the Mercedes-Benz Cup to reach his first final of the season. The top seed broke the Argentine in the seventh game of the first set and raced into a 5-2 lead in the second, closing out a 6-4 6-2 win with an ace.
The Los Angeles event is the American's first after two months out with a sciatic nerve injury in his back.
Agassi will face Luxembourg's Gilles Muller, who beat second-seeded Slovak Dominik Hrbaty 4-6 7-6 (7-4) 6-1.
The unseeded Muller saved two match points in the second set before cruising to victory in the third.
The 35-year-old Agassi has not won a title since his victory in Cincinnati last August.
"It was a big day, coming off two hours of real violent movements and throwing myself at everything I could get my racket on (in the quarter-finals).
"I was really interested to see how I was going to play. To be able to go out there and feel that good and move around against a guy (Chela) that was letting the ball fly was a great feeling for me.
"It gives me a lot of confidence, certainly for the final but as the summer unfolds, just to go out there and bring my game without hesitation."
