Gregory Polanco rejected offer

Gregory Polanco, the Pittsburgh Pirates' right fielder of the future and one of baseball's most highly regarded prospects, rejected a multiyear contract offer during spring training, according to multiple media reports.

Polanco turned down a seven-year deal that also included three team options, which would have allowed the Pirates to buy out his first three years of free agency.

The contract would have been worth between $50 million and $60 million had Pittsburgh exercised all three option years, according to CBSSports.com.

Pirates general manager Neal Huntington would not comment on Polanco's reported rejection of the deal.

"As we have done in prior situations, we will refrain from commenting on any player-specific contract rumors," Huntington said in a statement released by the team.

Polanco, 22, has been one of the most dominant hitters in the minors this season and is expected to debut with the Pirates at some point this season. He is batting .392 with four home runs, 27 RBIs and seven stolen bases in 30 games this year at Triple-A Indianapolis.

Polanco figures to eventually be the primary right fielder for the Pirates (13-20), who are off to a slow start this season and have struggled to get consistent offensive production from their right-field platoon of Jose Tabata and Travis Snider.

The 6-foot-4 Polanco was ranked earlier this year as baseball's No. 13 overall prospect by ESPN Insider Keith Law.
