Infielder Martin Prado reached a four-year extension worth $40 million with the Diamondbacks on Thursday, reports NBC Sports. Arizona bought out Prado's arbitration year this year and added three more years through 2016. Prado made $4.75 million with the Braves last season. His arbitration demand was $7.05 million and the Diamondbacks countered with $6 million.
Prado, along with Randall Delgado and minor league prospects, went to the Diamondbacks in the trade that sent Justin Upton to Atlanta last week. The 29-year-old hit .301/.359/.438 last season and played the majority of his games in left field, although he also spent time at all four infield positions. Prado will play third base for the Diamondbacks.
