Let’s be honest here, you are worried about Hector Rondon.
Almost every recent televised appearance in Spring Training or the World Baseball Classic has shown the former Cubs closer getting shelled. Type “fix” and “Hector Rondon” into a Google search and you’ll be inundated by several articles and comments refarding the Venezuelan reliever’s struggles this spring.
But those games didn’t matter, right?
In this post, we’re going to compare the PitcHFX data from Rondon’s 2016 Spring Training performance to this recently concluded preseason. We’ll particularly look at release point variance, velocity, and pitch movement. Although there are similarities between the two sets, there are stark differences, too.
