SURPRISE, Ariz. - Michael Chang won his second career title on the PowerShares Series Friday night, defeating Mark Philippoussis 6-2 in the one-set final of the Cancer Treatment Centers of America Championships, the 12th and final event this year on the U.S. circuit for champion tennis players over the age of 30.

Chang's previous title came in 2011 in Washington, D.C. when he defeated, in succession, Pete Sampras and Jim Courier. Chang dedicated his victory Friday to his grandmother, who passed away earlier this week.

"It's been an emotional week," said Chang, the 1989 French Open champion. "I'm sure my grandma was looking over me tonight. I was happy to (win) for her."

Chang broke the Philippoussis serve at 1-1, using his crafty groundstrokes to move his Australian opponent side to side, controlling points from the baseline. Chang made a high percentage of first serves, committed virtually no errors and registered another service break in the seventh game, before closing out the relatively quick championship match.

Philippoussis, who won the 2010 title in Surprise, was a late substitute in the field for Sampras, who withdrew due to continued troubles with his right shoulder.

Earlier in the night, Chang beat Courier 7-6 (5) in the first semifinal. Chang served for the match at 6-5, but Courier immediately broke back to force the decisive tie-breaker, saving four match-points in the process. Chang ripped an inside out forehand winner to take a 4-2 lead in the tie-breaker and never looked back, hitting a forehand winner on match point to advance into the final.

Philippoussis, a two-time Grand Slam tournament runner-up, beat Todd Martin, another two-time Grand Slam tournament runner-up, in the other semifinal 6-3.

The win earned Chang 400 PowerShares Series rankings points to move him to the No. 6 ranking position in the final 2014 points standings. The 200 points for Philippoussis moved him into a final ranking position of No. 7, tied with Ivan Lendl. John McEnroe won the PowerShares Series points championship for the first time in his career, finishing with 1600 points and four tournament titles.
