CHICAGO -- With four weeks left in the regular season, the Rockies will get the chance to see what they've got in certain young players. They’re hoping that some of them take this opportunity and run with it. 

Alan Trejo fits under that category of a player doing all he can to make an impact in the Majors. His two-run homer in the Rockies’ 4-2 loss against the White Sox on Tuesday night at Guaranteed Rate Field helped to show Colorado the type of player he can be for the team. 

“I think with him, he has Major League ability,” manager Bud Black said. “We had a pretty good shortstop this year in [José] Iglesias, so Alan is getting a little bit more playing time now. But Alan’s very capable.” 

Trejo’s season has been up and down with the Rockies, literally. After making the Opening Day roster, the 26-year-old has been optioned three different times to Triple-A and only appeared in one Major League game from May through August.

But he remained positive and confident throughout those times. 

“Taking it one day at a time and trying not to put too much pressure on myself and just allowing the game to come to me,” Trejo said of his mindset. “That’s probably the biggest thing I’ve done.” 

But Trejo’s call-up on Sept. 1 to fill in for the injured Iglesias has been a bright spot for the Rockies. The middle infielder has played in eight of the Rockies’ last nine games and points to that consistency in the lineup as the difference this time around.

“I’m playing every day, so it’s more like what I got to do in Triple-A,” Trejo said. “It’s more of what kind of player I am. Being able to play every day definitely helps stay in a rhythm, see the ball better, have better at-bats, and it’s easier to decompress after a game. After playing maybe two games in a week, it’s hard to digest that. But when you get to play every day, you get to move on and know that the next day is going to come.”

Entering September, Trejo slashed .231/.250/.333 with one homer and six RBIs across 11 games. In September, he has slashed .320/.393/.640 with two homers and five RBIs across eight games. 

His second homer in four games came on Wednesday, when he sent White Sox starter Michael Kopech’s hanging slider into the left-field bullpen. 

“I was being aggressive,” Trejo said. “I swung at a fastball up early in the count, just trying to zone him in a little bit. But for the most part with two strikes, still trying to be aggressive and put the ball in play.”

That added power in the big leagues has been a result of his work in the Minors this season. Trejo hit 16 home runs and 20 doubles with 52 RBIs with Triple-A Albuquerque. 

This pop in his bat helped him return to the Rockies, especially after a red hot August. He batted an impressive .358 (29-for-81) with seven doubles and eight homers in 20 August games with the Isotopes.

Trejo’s addition to not only the Rockies’ offense, but also to their defense has been key. Although he made his second error of the season in the eighth inning, it’s something that doesn’t happen quite often for the shortstop. He entered Wednesday with just one error across 79 chances this season in the Majors.

“I think he’s a good defender,” Black said. “That error in the eighth was uncharacteristic of Alan and how I think he can play defense.” 

In the small sample size, Trejo has been a nice fill-in at shortstop with Iglesias nursing a right thumb bone bruise. Although Iglesias is progressing from his injury, there is no timetable set on his return to Colorado’s lineup. 

“He’s improving in the training room daily, so gradually getting better,” Black said. “No timeline yet, and we just have to make sure the grip strength and getting a bat in his hand is comfortable.” 

It remains unknown what will happen to Trejo when/if Iglesias comes back this season. But one thing is for certain: the young shortstop is making the most of his opportunity with the Rockies. 

“He’s got the skill set that plays and he’s getting an opportunity here now to show it,” Black said.
