Blue Jays’ Gausman increasing four-seam fastball to deadly pitching formula

In current years Kevin Gausman’s major plan of assault has been easy.

Fastballs up. Splitters down. 

While that’s an oversimplification, it’s the essential thrust of what the Toronto Blue Jays starter will be anticipated to do in any given outing.

He’ll combine a slider in there every now and then, and possesses a changeup thrown with out the break up grip — however attacking the highest of the zone with the heater and the underside together with his signature splitter is what makes him profitable.

While the Chris Bassitts of the world assemble deep repertoires and orchestrate confounding pitch sequences Gausman performs the hits. 

The right-hander’s velocity is sweet sufficient to pour in fastballs excessive, and that pitch tunnels nicely with splitters beneath the zone — which means that hitters can get simply caught between the 2 pitches.

Gausman is utilizing this combo as his bread and butter in 2023 as soon as once more, however regardless of the actual fact his pitch combine is kind of the identical this yr, he’s made a bit of tweak. Instead of dwelling up excessive together with his heater, he’s throwing it low extra typically.

Here’s the share of his fastballs that have been within the prime third of the zone above in comparison with the underside third or beneath over the previous two seasons:

While this isn’t a radical change, it’s clear that throwing four-seamers down has change into extra of a precedence for Gausman. 

That appears counterintuitive as a result of low fastballs don’t generate as many whiffs and when Gausman targets the underside third of the zone the pitch is now not as simply mistaken for his splitter in its simplest location — slightly below the knees.

Another overlay from the incomparable Pitching Ninja supplies a bit of perception on that.

When Gausman throws the fastball low he’s tunneling it with a distinct type of splitter — the one he completely buries.

This creates an fascinating swing-decision dilemma for hitters. Gausman’s opponents are conditioned to put off something that appears low, as a result of likelihood is it’s a splitter that’s going to fall out of the zone. 

That leaves them vulnerable to getting frozen by the low fastball. This season, they’ve swung at pitch far much less steadily the decrease it’s.

Gausman has 11 referred to as strikeouts this season, and so they’ve all come through the heater within the center third or beneath:

That might not look like an enormous quantity, however Gausman has by no means exceeded 32 wanting strikeouts in a season, so he’s nicely on his technique to breaking new floor.

If hitters get sensible to the veteran’s low heaters and begin to get the bats going in opposition to pitches that appear to be coming in low, they open themselves as much as waving at splitters within the dust.

That could also be a think about Gausman throwing his splitter decrease than ever this yr.

Gausman’s final begin on April 29 showcased simply how dynamic he will be when he’s that includes the low fastball. This is the place he positioned his heaters on Saturday:

His fifth-inning battle with Sam Haggerty was the right instance of a hitter’s reluctance to swing at his low fastball, even when he’s been throwing it persistently.  

After lacking with a splitter down and a heater up-and-in, Gausman threw Haggerty 5 consecutive fastballs no increased than the center of the plate.

He checked out 4 out of 5 of them — and proceeded to let a 3-2 pitch that was clearly a strike go proper by him.

In different circumstances, Seattle Mariners hitters clued into the low fastball, like Eugenio Suarez who gave this 97.2 mph pitch an excellent rip:

On the very subsequent pitch, Gausman went to a splitter manner beneath the plate which will have seemed like a low fastball to Suarez on the way in which in. The Mariners slugger — who has a chase price that’s within the 77th percentile — made an unsightly examine swing on the type of pitch he hardly ever struggles to put off, and shouted an expletive on his manner again to the dugout.

Gausman has elicited 9 swinging strikes on pitches Statcast categorizes as blocked by the catcher this season. It’s in all probability not a coincidence that he acquired these in a sport the place Seattle’s lineup needed to fear concerning the right-hander stealing strikes on the backside of the zone together with his fastball.

Nothing is altering with the 32-year-old on a basic degree. He’s nonetheless a man who’s as straightforward to know as he’s arduous to hit. This yr it looks as if he’s tinkering together with his formulation the tiniest bit without having to find a brand new pitch, grip, arm angle, or launch level.

Gausman is simply taking one thing that works extremely nicely, and increasing on it through the use of a barely completely different iteration extra steadily. He was already a headache for hitters to cope with, however now they’ve acquired a bit of bit extra to consider.
