Diamondbacks close to extension with Justin Upton

FOX SPORTS is reporting that the Diamondbacks and Justin Upton are closing in on a six year extension worth 51 million dollars. Upton, 22, hit .300 last season with 26 home runs and 20 stolen bases in 138 games last season. He is a career .272 hitter in three professional seasons. 

The deal, which will buy out all three years of arbitration, is a great deal for the Diamondbacks. GM Josh Byrnes is certainly a proponent of signing players to guaranteed contracts during their arbitration years, having done so multiple times throughout his time as a GM. 

If Upton can prove to stay healthy for another full season, he should be on his way to another All-Star caliber season.
