I just went back and took another look at Moncada's Minor League career. I don't know why we should be surprised that he hasn't been any better than he has. He really never demonstrated any ability to dominate, in the Minors. He had a 30% strike out rate there, and we had no reason to think that it would improve, in the Majors.
If he were a prolific slugger, hitting 40 homers, his strike outs might be acceptable. However, he didn't hit for that much power, in the Minors and he isn't anywhere near that, now. I've said it before, but to me, he looks like a very "well built, speedy, athletic and "flashy" player, with a pretty LH swing. In other words; a lot of style and not much substance. To this point, the style hasn't translated to great baseball skill. Let's hope that he develops the skill, but so far, he really isn't very good.
I'd like to see if he could hit LH pitching, as a left handed hitter, like most of the great left handed hitters do. At this point, he is worthless, as a right handed hitter.
I'd also like to see where else he could play. We've discussed this, at great length, but it bares repeating; Second base should belong to Madrigal. I have a feeling that he is soon going to push the issue, because he doesn't really profile anywhere but second base, and that is where he should stay. Moncada might better be utilized at third. I don't really care what position he prefers, he isn't good enough to demand that the team accommodate his preference. He has the arm to play there and Madrigal does not.
It's hard to justify keeping Eloy at AAA, considering how much better he has hit there, than Moncada did. Yet Moncada got the promotion pretty quickly. Eloy appears to be a much better hitter than Yoan and I'll be surprised if he doesn't have a better career. That's ok, if Yoan ends up hitting anything close to what Jimenez is likely to produce, he could be a valuable core piece, given his other tools.
I'm not giving up on him, but I admit that I'm disappointed with Moncada's results, so far.
