Some observations
Seven of the ten position players on the list were drafted out of high school.
Just one of ten pitchers on the list was drafted and signed out of high school.
Only five of the ten position players on the list are first round picks.
Three of 10 pitchers are first round picks.
Position players on the list not picked in round 1 were selected in rounds 4, 8, 9, 12, and 19.
Pitchers on the list not selected in round one were picked in rounds 2, 2, 2, 3, 6, 11, and 29.
Seems like the Twins should draft position players out of high school and pitchers out of college.
