The Chicago White Sox have made free agent infielder Manny Machado a seven-year, $175 million offer according to ESPN's Buster Olney.

Bob Nightengale of USA Today tweets the offer was made "about two weeks ago" and the White Sox haven't felt the need to alter it and bid against themselves. 

Olney points out that their approach is similar in some ways to Boston's last off-season with free agent outfielder J.D. Martinez. The Red Sox offered Martinez $100 million and waited for two months, eventually settling on a five-year, $110 million deal in February.

Olney also wonders that if a seven-year, $175 pact is Chicago's best offer, could Machado and the New York Yankees re-visit a potential deal? Doubt of the Yanks signing Machado emerged once New York brought in shortstop Troy Tulowitzki and second baseman D.J. LeMahieu earlier this off-season.

The reported offer from the White Sox is significantly less than Max Scherzer's deal of seven years and $210 million and Zack Greinke's six-year, $206.5 million contract of comparable term.

ESPN's Jeff Passan reported last week that the White Sox might be willing to stretch their offer to as high as 10 years. 

Jon Heyman of Fancred Sports reported last week Machado's camp is claiming there is also a mystery team involved in the bidding, but the validity of the claim is unknown.

Machado, 26, hit a career-high 37 home runs last season to go along with 107 RBI and a slash line of .297/.367/.538.
