Tu, 16, Upsets Coetzer in Second Pro Match

Meilen Tu, a 16-year-old from Northridge playing only her second professional match, upset eighth-seeded Amanda Coetzer, 6-1, 6-3, on Monday in the opening round of the Virginia Slims of Philadelphia.

Coetzer is ranked No. 16 in the world. Last year, the South African won tournaments in Australia and Japan, but she was able to win only one service game against Tu--the fourth game of the second set.

A long deuce battle ensued in the ninth game of the second set between the two, each using a two-handed backhand. Tu closed the match when Coetzer hit a lob out of court.

“I knew if I played well, I’d have a chance,” said Tu, who lost to Meredith McGrath, 6-3, 6-4, last Tuesday at Oakland in her professional debut. “I knew she was a little bit nervous because I came out playing pretty well. I was attacking right away. I didn’t give her any errors.”
