Tyler Duffey is one of my favorite Twins, I won't hide from that fact. His mind-bending array of curve balls has my tender heart all aflutter. At the same time, I admit he's not a perfect pitcher. As much as his benders bend, his modest heater tends to be straight as a ruler, and his two-seamer is so-so. However, something has changed since Duffey retreated to the bullpen. Mainly, he discovered that he could increase the angle of his pitches to right handed batters by starting from the 3rd base side of the rubber. Suddenly his benders sweep almost impossibly far, like we see from legendary lefties. Suddenly he can throw his curve right at the front knee of a hitter, and it breaks past the plate, to the far side. Most hitters cannot make themselves keep their knee in the path of a ball traveling over 80 mph. The result is some gloriously clumsy swings as hitters are bailing and flailing helplessly. It's hard to cover the plate when your butt is flying the other way. Duffey's new trick also helps his fastball, which still isn't amazing, but now, when he throws it inside, the hitter has to wonder, will it bend a foot, or go straight? Is this ball going to hit my knee? This makes Duffey's inside fastballs much more intimidating. The overall impact of this change is that Duffey appears to have solved the problem that was preventing him from being a successful starter. He now appears to be reasonably effective against hitters on both sides of the plate. So, should the Twins test the waters of letting Duffey start, one more time? I believe they should. On the other hand, Duffey also is the team's most flexible relief pitcher, so maybe he's this season's Trevor May. Also, I have noticed another relief pitcher that is starting to look like a possible starter: Taylor Rogers. This young man appears to be filling out his frame, and his stuff appears more and more like something you might like in a starting pitcher. For the same reason as Duffey, Rogers may wind up sticking in the pen for now. The team needs reliable relievers as much as good starters.
