At least one MLB general manager believes Washington Nationalssuperstar outfielder Bryce Harper will leave the organization as a free agent this offseason to sign with the NL East rival Philadelphia Phillies.

On Thursday, Jon Heyman of Fancred reported the Chicago Cubs, Los Angeles Dodgers, New York Yankees and San Francisco Giants are among the other clubs linked to Harper, but the unnamed executive is predicting he'll land in Philly.

"I think Harper winds up with the Phillies," the GM told Heyman.

The 25-year-old Las Vegas native, who struggled in the months leading up to the All-Star Game, has come alive since the Midsummer Classic. He's posted a .352/.448/.682 triple-slash line with seven home runs in 88 at-bats after winning the Home Run Derby.
