2017 New Pitch Tracker

This marks the fourth consecutive spring for tracking new pitches at Fangraphs. In 2014, the series was launched with a piece featuring both a retired and current pitcher and their insight into adding new pitches during the offseason and/or in camp. The 2015 tracking was done at RotoJunkieFix where I serve as the CIO which is just a fancy title for the guy that keeps a 20+ year old fantasy community up and running in his spare time. By popular demand, the 2016 New Pitch Tracker gained front page real estate here and I updated it throughout the spring with help from Jeff Zimmerman and others scraping the stories from the web and the crew at BrooksBaseball helping validate the pitches. That same support model will be in place this year for the extended 2017 Spring Training.

The follow-up work in 2014 showed that 17 of the 23 pitchers that faced at least 100 batters in 2014 improved their strikeout rate, 16 of 17 generated more swinging strikes while 15 of them reduced their contact rates. In 2015, even more pitchers tinkered with new pitches, but the gains were not as definitive. I did not do a follow-up piece to the 2016 new pitches to see whether gains were realized but that list included as many breakouts as it did busts. Perhaps a look back at those pitchers can be done this spring while we continue to compile the new list of new pitches over the next few weeks.

(3/7 update) – Did a radio interview with the Kevin Wheeler show in St. Louis talking about new pitches

Without further ado, here is the list of new pitches we’ve heard about in chronological order with links to the tweet or the story with the details of the pitch:
