Like Machado, Harper's market is robust.
Nightengale's report falls in line with Wednesday's report that the team is willing to offer each the ten-plus-year deals they are looking for, while the White Sox won't go beyond seven years.
Bruce Levine covers the Cubs and White Sox for 670 The Score. Nightengale tweeted just a few minutes later that Philadelphia will likely make the highest offer to both Machado and Harper, making it even more intriguing to see which player ends up where.
If any Sox fans have been paying attention this offseason, it appears that many writers that cover Major League Baseball aren't fond of the idea of either Harper or Machado playing on the south side. It appears the team knows that, and they are willing to break the bank to sign either player.
When it comes to the Yankees, they are the team Machado wants, but with them not willing to break the bank, the White Sox and Phillies could have a chance if they bid significantly higher than the NY franchise.

Machado - who the team met with two weeks ago - remains Philadelphia's primary focus, according to Salisbury, although several teams have been linked to the superstar infielder, including the New York Yankees.
