10. Adam Walker– Outfield
Date of Birth: October 18, 1991
Acquired: Drafted in the 3rd round (97th overall) of the 2012 draft
Walker had a huge 2015 season in Double-A. He has the same issues as Daniel Palka though, except he’s more talented and plays a position where his value is higher. His power is real, but his bat will need to improve a little before he can reach the majors, which could happen full-time around 2017. Walker will have to battle it out in the Twins crowded outfield, but if he continues to hit for power, the tool that makes him a high B-grade prospect, he will make the majors and stick.
9. Nick Burdi– Pitcher
Date of Birth: January 19, 1993
Acquired: Drafted in the 2nd round (46th overall) of the 2014 draft
Burdi is moving through the Twins system very fast and figures to be very impactful relief arm as soon as 2016. He could take over for Glen Perkins as closer at some point. Burdi is a high-end B-grade prospect and he could be a good relief arm for years in Minnesota. He is the best of the group of relievers that are coming up and could help the Twins build one of the better bullpens in baseball.
8. Stephen Gonsalves– Pitcher
Date of Birth: July 8, 1994
Acquired: Drafted in the 4th round (110th overall) of the 2013 draft
Gonsalves had a great 2015 season, and he is now in the picture as a member of the future rotation along with Berrios, Jay, and Stewart. Some view him as a better arm than Stewart at this point, but I’d like to see one more impressive season from him before I move him ahead. He could be in the majors by 2018 and he’s a high B-grade prospect. It’s pretty impressive that he’s left-handed and moving fast too because we all know that good lefty starters don’t grow on trees. Burdi and Tyler Jay could make a pretty impressive duo in a few years. Gonsalves has three average to above average pitches. He just needs to work on keeping his walks down for now.
7. Kohl Stewart– Pitcher
Date of Birth: October 7, 1994
Acquired: Drafted in the 1st round (4th overall) of the 2013 draft
Stewart was one of the top picks in the 2013 draft. He has been pretty solid as he’s climbed the minors and he has a very impressive fastball and some good offspeed pitches with good movement. Stewart could potentially be an ace in the future if the Twins give him time to develop and are careful with him. His floor is as a number-three starter who can flash brilliance but is a solid starter. He’s a low-end A grade for me and he could debut at the end of the 2017 season, before competing for a rotation spot in 2018.
6. Jorge Polanco– Shortstop
Date of Birth: July 5, 1993
Acquired: Signed as an amateur free agent, 7/6/2009
Polanco kind of reminds me of his teammate Eddie Rosario, who had a good debut in 2015. Polanco figures to compete for an infield job this spring. He has good extra base power and could have average home run power for a shortstop. Polanco should be a consistent hitter, who hits above average year in and year out and he won’t hurt you on defense. He’s also a lower grade A-prospect for me. Polanco can also steal some bases, and he will be a guy that the Twins can slot almost anywhere in the order and do a little bit of everything.
