Todd Martin defeats Michael Chang

MINNEAPOLIS -- Todd Martin used a vintage wooden racket to close out Michael Chang 8-5 on Friday night in the championship match of the Leeann Chin Challenge, the fourth event of the Champions Series.

Martin reached the final with a 6-4 win over Andre Agassi. Chang beat Jim Courier 6-4 in the other semifinal.

Martin earned 400 points in the Champions Series rankings. Pete Sampras remained on top with 900 points, while Chang moved into second place with 700. The top three finishers at the end of the series will share a $1 million bonus pool.
