Blackmon, 30, increases the number of Rockies to win the award to 14 in their 24 seasons. Colorado players have won a total of 26, and this is the eighth time that club has had multiple winners.

"I am honored and grateful to be recognized among such an amazing group of players," Blackmon said. "I am thankful for good health, the opportunity to play and the teammates and coaches I am surrounded with."
Arenado, who already has won the NL Gold Glove Award and the Fielding Bible Award for his defense in 2016, led the NL in RBIs for the second straight year with 133. He also hit 41 homers to tie for the NL lead, also for the second straight year. Arenado became the first player since Hall of Famer Mike Schmidt (1980-81) to lead the league in homers and RBIs for two consecutive seasons.
"I don't really set goals in numbers," Arenado said late in the regular season. "A lot of goals I set, I don't really like to say them out loud. I guess the one number goal I set is RBIs, getting to 100. It's a hard thing to do, it's important to the team and that's my job."
In 2016, Arenado also led the NL in total bases (352) and was second in runs (116), extra-base hits (82) and slugging percentage (.570). He also tied for second with 57 multihit games.
Arenado joined Chuck Klein and Jimmie Foxx as the only players in history with two seasons of 40 homers and 130 RBIs before age 26.
Blackmon finished fourth in the NL with a .324 batting average, and he also set career highs in hits (187), runs (111), doubles (35), home runs (29), RBIs (82), on-base percentage (.381) and slugging percentage (.522). His batting average, slugging percentage, hits and runs led NL outfielders.
The 29 homers from the leadoff spot led the league, and they were the most in the NL since Alfonso Soriano and Hanley Ramirez hit 29 and 32, respectively, in 1997. Blackmon's homers also are tied for seventh most by a leadoff man in NL history.
Blackmon bucked the Rockies' reputation as a team that can't hit on the road when he hit .313 -- 10th in the NL and seventh in Rockies history -- away from Coors Field. It was the highest road average for a Rockies player since Helton's .326 in 2004.
Blackmon ranks the road performance "very high" on his list of career accomplishments, because he is "sick of hearing about splits."
