The New York Yankees are negotiating with the fan who caught Alex Rodriguez's 3,000th hit ball, according to sources.

Zack Hample recovered Rodriguez's 3,000th hit, a solo home run against the Detroit Tigers on Friday.

Hample said that after the team's head of security offered some items for the ball, he declined, and then met with Randy Levine and Lonn Trost in Levine's office.

Levine had asked Hal Steinbrenner if the Yankees had an interest in pursuing Rodriguez's ball. Steinbrenner said they did, but a deal was not struck on Friday.

On Monday, the two sides met again. Yankees spokesman Jason Zillo said "substantial progress" had been made in finding common ground with Hample, who works with a charitable organization called Pitch In For Baseball.

"I'm flattered," Rodriguez said.
