The Pittsburgh Pirates have signed star center fielder Andrew McCutchen to a six -year, $51.5 million contract extension, according to the Pittsburgh Post-Gazette.

The contract will also reportedly contain a club option worth $14.75 million, meaning the team could potentially control the All-Star through 2018. The deal is designed to buyout his remaining arbitration seasons, and his first two years of free-agency.

Last season McCutchen hit .259/.364/.456 with 23 home runs, 23 stolen bases, and 87 runs scored. The 25-year-old is about to enter his fourth MLB season with the Pirates.

Pittsburgh initially drafted McCutchen No. 11 overall in the 2005 MLB Draft.
