The 22-year-old outfielder has not accumulated any service time.
The White Sox and outfield prospect Eloy Jimenez have agreed to a six-year, $43 million deal, Jeff Passan of ESPN.com reports.
Jimenez's deal is the largest ever for a player already in an organization who had not accumulated any service time.
The outfielder will receive $11 million over the first three years of the deal, including a $5 million signing bonus. Jimenez will then make $6.5 million, $9.5 million and $13 million in his arbitration eligible years, according to The Athletic's Ken Rosenthal.
The deal also includes two club options valued at $16.5 million and $18.5 million, per Rosenthal.
The 22-year-old is sure to be a useful addition to a White Sox club that went 62-100 last season.
Chicago opens its season on March 28 in Kansas City. Its first home series starts April 4 against the Mariners.
