This article explains why. It has a lot to do with the juiced ball. He's pretty much ditched his sinker and cut down drastically on his curve ball.
He concluded that with the launch angle revolution of recent years, it did not make sense to throw a pitch that has movement that would complement swings that have more upper trajectories.

This is a very interesting article for any baseball fan.
Jacob deGrom has ditched his sinker and minimized his curveball - (
New Window )
Since then, Paxton has made seven starts for a 2.98 ERA. Hitters are 10-for-69 (.145) against his four-seamer with a .261 slugging percentage during his August and September outings.
So, while it's certainly interesting to note that deGrom has been able to cut down on the HR balls allowed by utilizing his 4-seamer more often; it may be unique to him and not necessarily something more pitchers will do to try and counteract the juiced balls.
Decreased fastball usage from 60% to 50%
Decreased cutter usage from 22% to 19%
Increased curve usage from 14% to 24%
Added in new changeup at 4%

While Paxton's breaking ball has been his third most-used pitch, per Statcast, opponents have hit just .163 against it. For comparative purposes, batters have hit .270 against his fastball and .261 versus his cutter. Those numbers aren't a one-year mirage, either. For his career, opponents have a .183 average against the curve, versus .206 against his cutter and .254 versus his four-seamer, according to Brooks Baseball.

Pax has always been a fastball guy and a strikeout guy.
The 81 mph curve is how he's getting hitters off balance now. He's mixing in the 96/97 mph fastball and still using the 88mph cutter.
It's made a big difference for him and he's looked significantly better in recent weeks.
You and me both! :)
Also, sorry if I derailed this thread - I didn't mean to make it about Paxton. I actually found the linked article to be a good read.
deGrom has a legitimate case at another NL CYA this year. For me, it's between he and Max. Both of them are incredible. Ryu has tailed off a little bit - I'd vote for either of the other two guys before Ryu.
