Last May, Jeff Sullivan — along with others like this author and J.D. Martinez — hypothesized that pitchers might already be thinking about a way to adjust in the fly-ball era. The possible antidote? To work higher. After all, the swing changes that helped produce a surge in home runs were designed largely to address pitches at the bottom part of the zone, notably the growing number of two-seam fastballs directed there.
Said Martinez to this author last spring of how pitchers appeared to be adapting:
“Pitchers are countering it right now. The pitchers are always ahead,” Martinez said.
What exactly are the adjustments being made to his swing path? Martinez and I had not, apparently, reached that level of trust.
“That’s one of the things you don’t want to tell anyone,” Martinez said.
While Martinez would not reveal what he believes to be countermeasures to his swing path, it appears pitchers are trying to elevate their fastballs against Martinez.
The home-run surge — whether a function of the changing ball, evolving swing planes across the league, or a combination of factors — began in the second half of 2015 and has since, of course, continued. Jeff found that, in the second half of 2015 and 2016, the increase in home-run damage done by batters had largely occurred in the bottom half of the zone. So it made sense that pitchers, especially those with high-spin fastballs with a rising effect, would turn their attention upwards.
Pitchers like Jake Odorizzi, for example. It was Odorizzi who told this author last spring that he had become more committed to a high-fastball approach. The numbers bear that out: the right-hander utilized the high fastball more than ever last season. Of course, Odorizzi also allowed 30 home runs in 143 innings.
Odorizzi’s 2017 campaign led me to a pair of questions. First of all, were pitchers working up in the zone more frequently last season? And if so, was it working?
