The Rockies’ most prolific player of the last decade is saying goodbye to baseball.

Charlie Blackmon, a four-time All-Star who won the NL batting title in 2017, announced Monday that he’s retiring at the end of this season after spending his entire 14-year MLB career in Denver.

“As a kid you play the game because you love it, like nothing else matters. I still play the game that way, but I don’t feel like a kid anymore,” the 38-year-old bearded outfielder wrote in an Instagram post. “My perspective has changed. I have been blessed to call the city of Denver and the Colorado Rockies my baseball home for the entirety of my career. I am grateful for the support of this organization, my teammates, and most of all Rockies fans. It is with a thankful heart and a career’s worth of memories that I choose a new path.”

A second-round pick by the Rockies out of Georgia Tech in 2008, Blackmon enters the final six games of his career — which will all be at home — with a .292 career average, .831 OPS, 226 home runs, 797 RBIs, 991 runs and 333 doubles.

The numbers show he clearly benefitted from playing at Coors Field.

In 796 career home games, Blackmon as a .329 average, .939 OPS, 133 home runs and 477 RBIs, while in 822 career road games he hit .256 with a .722 OPS, 93 home runs and 320 RBIs.

Blackmon earned his first All-Star nod in his first season as a full-time starter in 2014, but it was his dominant four-year stretch from 2016-19 that he’ll be most remembered for.

In 2016, he hit .324 with a .933 OPS, 29 home runs and 82 RBIs, and he followed up with a monster 2017 season that saw him win the batting title with a .331 average while leading the majors in hits (213), runs (137), plate appearances (725), triples (14) and total bases (387). He registered career-highs of 37 home runs and 104 RBIs that season, finishing fifth in the NL MVP race and leading the Rockies to the playoffs for the first time in his career; they lost to the Diamondbacks in the wild-card game.

Blackmon led Colorado back to the postseason in 2018 after hitting .291 with an .860 OPS, 29 homers and 70 RBIs. They defeated the Cubs in the wild-card game before getting swept by the Brewers in the NLDS in Blackmon’s final postseason appearance, as the Rockies went back to the cellar, bottoming out last year with their first ever 100-loss season. They’re 60-96 entering their final six games this season.

His last All-Star season was in 2019, when he hit .314 with a .940 OPS, 32 home runs and 86 RBIs.

Blackmon is hitting .249 with 11 homers and 48 RBIs this season.

“When Charlie told me of his plans to retire I got a little emotional, as I’m sure many fans will when they see the news that one of the greatest Rockies of all-time will no longer take the field,” Rockies owner Dick Monfort said in a statement. ”Charlie’s passion and dedication to the game of baseball, this organization and our great fans was on display every single day and I can’t thank him enough for pouring his heart into every game and every at-bat over the course of his 14 years here. Charlie is a Rockie to his core.”
