Brenton Doyle makes baseball look effortless.

The Gold Glove center fielder glides across the vast expanses of Coors Field. He goes Superman to make diving catches and emerges with a know-it-all grin. His powerful swing sends balls soaring over the fence.

We can see all of that. We don’t see the monotonous work that transformed Doyle from an offensive liability into a budding star. And we don’t understand what it takes for a major league player to recognize a major flaw and embrace a major change.

But the 26-year-old Doyle did that, altering his swing over the course of one strenuous offseason and, in doing so, turning himself into a promising young hitter for a Rockies team trying to chart its future.

“It is not easy to change your swing — especially not in the big leagues,” veteran third basemen Ryan McMahon said. “But ever since Doyle came to spring training, he’s looked the same every time up to the plate. He’s been so much more consistent. I’m kind of amazed. The dude’s been really impressive.”

Doyle’s statistics illustrate the turnaround.

After slashing .203/.250.343 as a rookie last season, Doyle entered Saturday night’s game slashing .263/.324/.471. He hit 10 home runs in 126 games last year. He’s hit 20 in 110 games so far this season. He’s dramatically cut down on strikeouts while increasing his walks.

Doyle’s diligence was rewarded when he was named the National League player of the month for July, becoming just the 12th Rockie in franchise history to win the monthly award. In 25 games, he slashed 333/.394/.800, with 11 home runs, seven doubles, one triple and 27 RBIs. He was the first Rockies player to hit 11 home runs in July since Carlos Gonzalez in 2015.

In Colorado’s 6-5 win over the Braves on Friday night, he reached 20 homers and 20 steals in 110 games, a feat accomplished five other times in club history — by Hall of Famer Larry Walker (1997), Dante Bichette (1994, ‘ 96), Ellis Burks (’96) and Gonzalez (2013).

“I like being in that company,” Doyle said.

Doyle already had enormous self-confidence and solid pitch recognition. His improvement was based primarily on fixing flawed mechanics.

“The biggest thing was trying to minimize the movements in my swing,” he said. “That allows my body to stay quiet and it allows my eyes to work a little bit better. Also, when things aren’t going well — and that happens all the time in this game — if your swing is really simple, it’s easier to make little adjustments. You don’t have to work so hard on it because there aren’t so many moving parts to fix.”

Doyle’s fundamental problem last season was his tendency to drop his hands when he began his swing. That bad habit disrupted his timing and caused him to move his head.

Hitting coach Hensley “Bam Bam” Meulens started tinkering with Doyle’s approach last season, and the Rockies staff told Doyle that some major changes were needed in the offseason. Teaming up with personal hitting coach Kevin Lachance back in his native Virginia, Doyle got to work.
