SAN ANTONIO -- A 14-year-old girl testified Monday that she and boxer Tony Ayala Jr. had sex twice last fall after she had vigorously pursued him for months, and that word of the relations got out when she mistakenly told a guidance counselor at her junior high school.

The testimony came on the first day of a hearing on whether to revoke Ayala's 10-year probation for a September 2001 burglary conviction.

But under cross-examination intended to sully her credibility, the eighth-grader from suburban San Antonio conceded that she had lied to authorities previously when telling them that her stepfather had molested her for several years.

Ayala, released from prison in 1999 after serving 16 years for raping a New Jersey schoolteacher, said the current allegation of statutory rape is not true. The decision to revoke the burglary probation will be made by state District Judge Maria Teresa Herr.

The girl, whose identity has been protected by the court, gave a detailed account of how she met Ayala when she took up boxing at his family's gym after getting into a fistfight at her school while in seventh grade.

She said she met Ayala, 39, during her first day at the South Zarzamora Street Gym, and that she developed a heavy crush on him right away.

She said that she later told Ayala how she felt, and that he kept his distance.

"He said that I was too young, and that we would have to wait until I was of age," she said while being questioned by Bexar County prosecutor Scott Simpson.

The girl said she and Ayala built up a close platonic relationship over the months, and that she confided in him about her troubles in school and other problems. Last August, she testified, she again tried to seduce Ayala and that he again resisted.

But on Nov. 14, she said, the pair started kissing in his car in a supermarket parking lot, which led to a brief sexual encounter in the vehicle's backseat.

About two weeks later, she said, the pair had intercourse again, this time in a bedroom at the home of Tony Ayala Sr. where the girl often spent weekends.

She said she was elated about the new intimacy with Ayala, and that she told her school guidance counselor about it in early December, unaware that school officials are required under Texas law to alert the state Child Protective Services office.

"I told her out of excitement -- I was happy," the girl said, adding that she still has strong feelings toward Ayala. "I didn't think she was going to report it."

She said she first wrote out a statement to CPS denying that anything had happened because she didn't want to get Ayala into trouble, but that she later admitted that the pair had had sex.

Defense lawyer Jimmy Parks aggressively went after the girl's credibility, at one point openly accusing her of being a liar on the stand.

He questioned her about her many disciplinary problems at school, which included suspensions for fighting, getting caught with a knife and other offenses.

Parks worked to link the girl's decision to tell the guidance counselor to an upcoming hearing on whether to permanently expel her from school, suggesting that she made up the story about Ayala as a way to get out of the hearing. She denied that claim.

But Parks got her to admit that she had once falsely told a CPS caseworker that her stepfather had been molesting her for four years. She concurred with Parks that she made up the story, which she later recanted, because she was mad at her stepfather because he got upset over her relationship with Ayala.

Parks also got the girl to admit that she had gotten angry with Ayala when he wouldn't speak to her at the gym for a week, though she denied the lawyer's contention that she invented the sexual encounters as revenge.
