After meeting with Bryce Harper for five hours in Las Vegas on Saturday, the Philadelphia Phillies are considered the favorites to sign him, according to a report.

Bob Nightengale of USA Today cited three sources in his report.

The Washington Nationals, who were believed to be the favorites after meeting with Harper over the holidays, now believe they are a "long shot" to sign Harper.

The Phillies are expected to make a formal offer to Harper this week.
