Sometimes the learning curve for top pitching prospects takes much longer than anticipated and often these post-hype sleepers can turn out to be extremely valuable fantasy baseball commodities. Kansas City's Danny Duffy belongs in this category since the power lefty was at times unhittable in 2016 as he struck out batters at an ace-like 9.42 clip and posted a 3.51 ERA that was inflated due to some September struggles. What perennially held back Duffy previously was downright terrible control that allowed opposing pitchers to lay off his 98-mph fastball and wait for the guy to beat himself with errant throws. It call came together at the age of 27 last season however as Duffy made a huge breakthrough with his walks in posting an impeccable 2.10 BB/9 rate. With hitters no longer being able to lay off the missed pitches, Duffy's strikeouts really ramped up and his .239 BAA was phenomenal. A .291 BABIP was only slightly lucky and so the key now will be whether or not Duffy can replicate his excellent 2016 control. That is up for debate since Duffy's numbers there a year ago were in outlier territory but he also burned so many owner before that his draft price will not go up as much as you might think. If you can snag Duffy as an SP 4, you did well.
