From Fangraphs: #20 on top 30 Minnesota Twins prospects https://www.fangraphs.com/blogs/top-30-prospects-minnesota-twins/ Littell is a tough evaluation for scouts. He has a maxed-out 6-foot-4 frame, has been traded twice in the last two years, sits 87-90 or 89-91 depending on when you see him but can reach back for a 93 or 94 occasionally, and doesn’t have a plus pitch or plus command. That would normally point to an organizational player who doesn’t project for a big-league career of any consequence, but Littell is now in Triple-A and keeps performing, figuring out ways to set up hitters and get them out. His curveball flashes 55 at times, his changeup is average to a hair above, and he mixes in a slider against right-handers: the weapons are not overwhelming. Scouts will always question how effective he can be, and it’s likely that his big-league career is as a back-end starter barely surviving on guile and filling in as a long reliever at times. Because we don’t completely understand why Littell keeps performing, we’ll stick him here. [shrug emoji.]
