Baseball officials still see the Nationals as the favorites for Michael Bourn, while the Phillies are seen as an early favorite for Upton.

After trading away starters Hunter Pence and Shane Victorino this summer, the Phillies entered the offseason with several holes in their outfield. They figured to target outfielders, and specifically a center fielder, this winter, but it wasn’t known how much the team would be willing to pay considering their disappointing 2012 season.

General manager Ruben Amaro Jr. likes to act quickly when it comes to the offseason so he could pounce on Upton, who’s regarded as one of the top free agent center fielders available. The 28-year-old, who could cost $60 million over five years according to Heyman, hit .246/.298/.454 with 29 doubles and 28 home runs last season. He owns a career line of .255/.336/.422.
