More national prospect rankings are being unveiled each week. The Twins have been ranked as having one of the top two or three farm systems in all of baseball again this year. We know that the organization has some high-end, potential impact big leaguers and several of them are getting close to being promoted. Because of that, Twins Daily is going to, over the next few weeks, produce our Top 20 Twins Prospects. Today, we begin with our choices for Twins prospects 16 through 20.

Minier was the Twins big international signing in 2012. He got a $1.4 million signing bonus as a 16 year old from the Dominican Republic. His professional career began in 2013 with the GCL Twins where the switch-hitter hit just .214/.252/.455 (.707) in 31 games. However, he still showed his tremendous power potential with five doubles, two triples and six home runs. In the offseason, he had shoulder surgery. Few believed he would be able to stick at third base, so he began to work in the outfield and some at first base. He returned to the GCL in 2014 and was much improved. His plate discipline and his power were able to develop. Minier just turned 19 last week and should spend 2015 with the Elizabethton Twins.Harrison was the Twins' first of two supplemental first round picks in the 2011 draft. His career began in 2012 when he hit .301 (.845 OPS) with 21 extra base hits in Elizabethton’s short season. He moved up to Cedar Rapids in 2013 and hit .253. However, he got on base almost 37% of the time and hit 28 doubles and 15 home runs. Following that season, he made the move from third base to left field. In 2014 he played in Ft. Myers. He continued to show very good strike zone judgment. He showed doubles power in the pitcher-friendly Florida State League, but the 6-1, 220 pounder hit just three home runs. Harrison will be 22 years old through the 2015 season. I suspect he’ll start the season back with the Miracle, but he should get an opportunity to move up to Chattanooga during the season. He is a solid hitter who uses the entire field. He cut his strikeout total by about 30% from the previous season in the exact same number of plate appearances. He has tremendous strength, so expect him to put up bigger power numbers as he moves up.With the Twins fifth round pick, they drafted their fourth straight college relief pitcher. They took Jake Reed who was the closer for the University of Oregon in 2014 after two years as a starter. He signed quickly for $350K. He pitched in four games for Elizabethton and 16 more for Cedar Rapids. In all, he put up video game numbers. For his work, he received an invitation to represent the Twins in the Arizona Fall League where he gave up just one run. Reed has a fastball that sits 93-95 mph and runs in on a right-handed hitter. He also has a very sharp slider that dives away from a right-hander. He will be just 22 years old through the 2015 season. He likely will start the season in Ft. Myers but should move up to Chattanooga fairly quickly. There is a chance he could be in the big leagues in 2015.Turner was the Twins third round pick in 2013 out of Ole Miss. He was awarded the Johnny Bench Award as the top college catcher that season. He spent that summer in Elizabethton. After going to big league spring training, Turner skipped the Midwest League and jumped to Ft. Myers. On May 25, he was hitting just .188. From that point on, he made some adjustments and hit .282/.360/.427 with 19 of his 25 extra base hits. At 6-3 and 230 pounds, he presents a big target behind the plate. He has the trust of his pitchers and his strong arm helped him to throw out 32% of would-be base runners. He will again go to big league spring training with the Twins and should spend the season as a 23 year old at AA Chattanooga.At Rice, Duffey teamed with JT Chargois as co-closers. Duffey was the Twins fifth round pick in 2012 and pitched great in Elizabethton that summer. In 2013, he started in Cedar Rapids and quickly moved up to Ft. Myers which is where he began the 2014 season. After four starts with the Miracle, and a 3-0 record, he was moved up to New Britain. He made 18 starts with the Rock Cats and went 8-3. His season ended with three starts in Rochester where he went 2-0. As impressive, his strikeout rate rose at each level, from 5.2 to 6.8 to 9.0. Duffey’s fastball sits between 91 and 94 as a starter and 97 in the bullpen. He throws a cutter in the upper-80s. His 12-6 curveball is probably his best strikeout pitch. He’s still improving his changeup. At 6-3 and 230 pounds, Duffey gets a lot of his strength from his legs. He could go back to AA to start the 2015 season depending upon the numbers. However, if he does, he should be the first guy called up to Rochester. He was recently invited to big league camp as well.Check back later this week for Part 2 of the Twins Daily Top 20 Prospects Countdown.
