It’s been seven years since we last saw Jason Voorhees stalk and slaughter in a Friday the 13th movie. As we all know, it’s impossible to kill him, so it only makes sense that he may have reincarnated in the form of Jason Vargas (57.6% owned; +54.5%), the Kansas City Royals pitcher. In 13 2/3 innings, Vargas has an ERA of 0.66, a K/9 of 9.22, and a SwStr% of 13.1%. Those numbers would be akin to the other Jason wielding an AR-15 and mowing down his slow-running prey. Let’s delve into the KC iteration of Jason and see if anything can get unmasked. Vargas has been in the major leagues since 2005. Prior to this season, he never had a K/9 over 6.54 and a SwStr% over 9.2% (2016 was 10.1% but he only pitched 12 innings). There has been no velocity uptick, as the fastball remains in the 87 mph range. So, what can we attribute this early success to? Early in his career, Vargas was primarily a fastball, sinker, and change pitcher. In 2015, he really started to incorporate the curveball. This is when he started throwing the four-seam fastball more and sinker less. So far in 2017, he’s decreased usage of the four-seam fastball, increased the sinker usage while still throwing the curveball and changeup.
Please, blog, may I have some more?
