The Rockies are calling up top prospect Adael Amador for his MLB debut, manager Bud Black said after Saturday's 6-5 win over the Cardinals.

Amador, 21, who plays second base and shortstop, is the team's No. 1 prospect and the No. 32 prospect in baseball, according to MLB Pipeline. Second baseman Brendan Rodgers is battling a left hamstring strain and will be placed on the 10-day injured list, Black announced.

Though he's had a rough start in Double-A -- he's hitting .194 in 46 games this season for Hartford -- Amador homered in three straight games from Tuesday through Thursday. He also performed well in lower levels last season, hitting a combined .308 between Rookie ball and High-A with 11 homers and 45 RBIs. Scouts say the switch-hitter has advanced hitting skills for his age and has shown an ability to consistently barrel the ball from both sides of the plate.

In his last 24 games, Amador has slashed a more representative .255/.360/.489 and is 11-for-13 on stolen-base attempts. In the last nine games, he has sizzled at .359/.422/.846 with six of his seven total home runs this season.

"It's going to give Amador a taste of the Majors here for a short period of time until 'B-Rod comes back," Black said. "We're excited about that. It'll give us a chance to look at him. He'll be exposed to the pace of a Major League game versus a Double-A game. He's in good form at 21 years old. The thing that prompted this was the last 10 days he's been playing well. He's hit some homers, his batting average even though its below .200 it doesn't look great, he's been hitting well over .300 the last week or so. His defense has been fine. He's leading the Eastern League in walks and stolen bases, so there are some things to be excited about."

Amador has been solid on defense, showing good hands and footwork while playing mostly at shortstop, though some believe his long-term position is second base.

"I don't know if he's ready for what's going to be thrown at him, but it also gives him a good opportunity to see some things he needs to work on for down the road to get back up here," general manager Bill Schmidt said.

Double-A Hartford manager Bobby Meacham recently told MLB Pipeline's Sam Dykstra: "Especially with younger guys, I focus on what can be. The key for me is for them to learn the game. Everybody talks about numbers. I call that a lazy way to do things. The smart way is to add up what you know. That, combined with the numbers, will make you a big league ballplayer.

"If you just have numbers, then go to the next level and don't produce those same numbers, you're lost. You don't know enough to make sure those numbers work. I talked to him a little bit about it. I said, 'We're going to coach you hard. We're going to give you all the information. You're probably going to be information overloaded, but you have to sort through it and use what you can at this level, at this time in your life and at this time in your career. Then you pick up more knowledge as time goes on.'

"I don't worry about the numbers. At the end, they always come out well or should come out well if you know how to do things right in this game."
