Frankly I was not shocked to see Gee on the list, but I was a little surprised to see Nieuwenhuis appear on this list. Here are Goldstein's comments on Gee and Nieuwenhuis:
He struck out 165 in 161 innings—leading the International League in that category—and then posted a 2.18 ERA in five MLB appearances. Mets fans want to view him as a rotation answer. Here's the good part: he can throw up to five pitches. Here's the bad part: none of them (maybe his changeup) can miss bats consistently at the major-league level. In 33 IP with the Mets, he K'd only 17. Look at that stat more than the ERA; he's a fifth starter in all likelihood.Goldstein's comments are eerily similar to Toby's from last week. Gee had success in his brief stint with the Mets, but his overall #'s would indicate he was more lucky than good. Turn those numbers into a full season, and it won't be pretty.
Nieuwenhuis can hit and has gap-to-average power. The issue is more a matter of context. Evaluated as a center fielder (his current position), Nieuwenhuis is a potential above-average starter. The bad news is that his defensive reviews are marginal, as for many talent evaluators, he lacks the speed and instincts to stay up the middle. He might lack the run production ability to become an everyday corner outfielder in the bigs, though.So, with the bat, he has the "potential to be an above average starter" in centerfield, but the concerns are on the defensive end. Obviously his ability to stay in CF, is the key to his long-term value. If moved to a corner spot, I believe his ability to hit lefties and to make enough contact are the big issues for him moving forward.
