Personally, all three have at least two years before seeing major league....Berrios is just going out there and throwing.....has no clue as to his surroundings and just having fun.....lacks seriousness of the responsiblilities......this disrupts the flow a team and pitching staff.....Maturity two years ......Alex Meyer is as good as he will ever get....Major league hitters will figure him out fast and this will cause him to try and adjust which will lead to even more inconsistancy....Great guy but IMO will need a change over.....Kohl Stewart IMO best of the three but 3 years away for much the same reasons as Berrios except IMO he will better because than Berrios because of his physical and emotional stature.....but still 2-3 years from really moving to twins... IMO the Twins need to focus on Levi Michael's, Alex Wimmers, and Brian Dozier.....the combination of Michael's and Dozier at 2nd and short will create the quickest and best defense in the league....once they improve their hitting to .250+ TWins better move them lup fast or they are gone to another team....As for Alex Wimmers, get him up there now....he looks ready and confident.....he was ready in college so he is more than ready now....The sooner Twins can start him behind Gibson the stronger the rotation will be due to the different pitching styles.....Hitters will adjust but from one day of Gibson to Wimmers with different release points, arm angles, and pitches, hitters will have to make the adjustment fast because their swing have to change to get on the ball.....This would be fun to watch......My opinion....Really like to see these three up with the Twins after All-Star game this year.....
