The D-backs are going long with the newly acquired Martin Prado. On Thursday, the team announced that they have agreed to terms with their third baseman on a four-year contract. The deal means that Prado will be locked up through the 2016 season. In essence, the D-backs bought out the final year of Prado's arbitration eligibility and the first three years of his free agency.
The contract will pay him a total of $40 million. CBSSports.com's Jon Heyman reports that Prado's deal will break down as follows: $7 million in 2013; $11 million per in 2014, 2015 and 2016.
Prado, age 29, was acquired from the Braves as part of the recent Justin Upton blockbuster. He's coming off a season in which he batted .301/.359/.438 with 42 doubles and 17 stolen bases. Across parts of seven major-league seasons, Prado owns a career OPS+ of 109.
Prado was previously named to Venezuela's provisional roster for the upcoming World Baseball Classic.
