By 
Welcome to Mixing It Up, a weekly column where I take a look at beginning pitchers who are making notable modifications to their pitch mix or pitch shape/velocity. In this column, I’ll break down 3 to 5 pitchers every week who have actually revealed a modification in their profile that has me fascinated. It will not constantly be a pitcher who needs an instant include however might be someone who has actually worked his method onto our dream baseball radars or a pitcher I believe is set to start an efficient stretch. I’ll constantly attempt to ensure we have enough of a sample size to deal with and I’ll be blending in both shallow and deep league targets, so there must be a little something for everybody.
In the last couple of weeks we recognized some favorable modifications in Luis Medina , Steven Matz, Freddy Peralta , Cole Ragans , Brandon Williamson , and Chase Silseth prior to significant breakouts so ideally we can strike on a couple of more arms making appealing modifications.
With that stated, let’s dig in to today’s pitchers of note.
Joe Ryan – Minnesota Twins
Generally speaking, I do not like to invest excessive time examining modifications in simply one start since they can frequently be sustained by the particular challenger or how a pitcher feels his pitches are operating in the bullpen prior to the video game. Yet, when a recognized starter returns from a layoff and makes a variety of modifications, I believe it calls for a little a much deeper appearance.
Making his very first start in over 3 weeks, Joe Ryan had a visible modification in method throughout his 5 innings versus the Rangers. For beginners, Ryan, who has actually been utilizing a slider on and off all season to match his sweeper, in fact relied on his slider more frequently. He likewise increased the use of his splitfinger while showcasing more motion on the splitter and more extension in general.
Some of these modifications might likewise be the outcome of Ryan just being totally healthy after hanging out on the IL with a groin stress. There was never ever one clear minute when Ryan got injured, however he had actually enabled 31 made runs in 32.1 innings prior to going on the IL, so it’s possible that he was handling an injury for a while. A groin injury would have had myriad repercussions on his shipment from restricting his drive off the rubber to avoiding complete rotation on his release. Much of that might be the reason that we saw a dive in Ryan’s extension in his very first start back.
Now that he’s totally healthy, he has the ability to totally release, so the included extension, which decreased his release point and caused increased vertical break on his fastball might all be genuine modifications.
However, I’m less positive about the included drop on Ryan’s splitter, which dropped 3 inches more than prior to his stint on the IL. The pitch had simply an 11% whiff rate and 15% CSW because very first video game back, so it’s possible that the included motion has actually made the pitch simpler to recognize out of his hand. We will not understand that for sure till another start or 2.
The slider was likewise helpful for him in his one start, and the sweeper actually hasn’t been a terrific pitch for Ryan this season with a 12.6% swinging strike rate (SwStr%), 10.3% barrel rate, and 6.96 dERA (Defense Independent AGE). Mixing in the more difficult and tighter slider more frequently might not be a bad concept for Ryan, who would rise by discovering a more constant 3rd pitch.
I believe this variation of Ryan looked more like the early season variation that was a leading 20 beginning pitcher.
Bobby Miller – Los Angeles Dodgers
A novice season is frequently a rollercoaster of ups and downs and modifications. That’s precisely what we’re seeing from Bobby Miller, who break onto the scene by permitting simply 2 made runs in his very first 23 innings. He then got illuminated for 13 in his next 2 starts and published a 5.27 period in June and 4.64 AGE in July. Yet, Miller has actually started to recover in August with a 2.45 period and 16 strikeouts throughout 22 innings.
Part of that success might be credited to a clear modification in his pitch mix and pitch shape. After leaning on his sinker greatly early in the summer season, Miller has actually seriously called back his use of the pitch and started to rely even more on his four-seam fastball. He has actually likewise begun to gradually increase using his curveball, which has actually changed the slider as his main secondary pitch.
Those modifications all make good sense on the surface area. So far this season, the four-seam has actually been the remarkable fastball for Miller. It has a 9.9% SwStr%, 6.3% barrel rate enabled, and 2.57 dERA. Meanwhile, the sinker has an 8.0% SwStr%, 10.9% barrel rate enabled, and 4.80 dERA. Similarly, the curveball has a 3.45 dERA compared to a 4.59 dERA on the slider and just has a somewhat even worse SwStr%. That’s most likely why we’re seeing Miller’s strikeout amounts to drop a little late, while the outcomes in general have actually enhanced.
Another modification has actually been the motion profile on Miller’s four-seam as the season has actually gone on. As you can see from the chart below, pulled from Alex Chamberlain’s Pitch Leaderboard, Miller has actually increased both his vertical motion and his vertical method angle above average (VAA AA) as the season has actually gone on.
Alex likewise composed a post for FanGraphs in 2015 where he pointed out the value of Vertical Approach Angle, which is the angle at which a pitch approaches home base. He pointed out that VAA is an item of any/all of speed, pitch height, and release point. Based on Alex’s research study a favorable VAA AA highlights that the four-seam is flatter than typical and “the flatter a pitcher’s four-seam fastball, (1) the lower in the zone it can induce whiffs (per swing), and (2) the larger its margin for error throughout the zone.”
Well, Miller’s fastball seems getting flatter based upon its VAA AA and it has actually published an 11.2% SwStr% in the 2nd half of the season as compared to a 6.7% SwStr% in the very first half. We like to see that, and we like to see that Miller is relying more on than pitch now, which, when matched by strong slider and curves, provides him a much safer flooring to couple with his alluring ceiling.

Josiah Gray – Washington Nationals
Sometimes you get a pitcher who does not wish to make one modification to their toolbox however appears to be reconstructing on the fly. We’re seeing that a bit with Josiah Gray over the summer season.
As you can see, from July to August Gray has actually considerably changed the use of his slider, sinker, curveball, and cutter. That might raise your eyebrows, however what must raise them a lot more is that August has actually been, without a doubt, Gray’s worst month. He’s published a 7.79 period in 17.1 innings in spite of publishing his most affordable batting average versus (.239) of any month of the season. However, he has actually likewise enabled a 17.6% barrel rate in August, which lets us understand that despite the fact that he’s not enabled as lots of hits, he’s permitting even more difficult contact.
Part of that is not a surprise considering that Gray has actually enabled a 16.7% barrel rate on his curveball and a 13.3% barrel rate on his sinker in the 2nd half of the season. He has actually considerably increased the use of both of those pitches, and they have actually each carried out even worse than in their minimal use in the very first half of the season.
Considering the curve has the greatest SwStr% of any of his pitches, it makes good sense that Gray would have wished to make use of the pitch more, however it’s likewise totally possible that it’s a pitch that carries out much better in a lower function. Sometimes when players see a pitch more frequently and start to try to find that pitch, it ends up being simpler to get. Gray might have been experiencing success with the curve considering that it was his 4th most-used pitch and might frequently capture a player off guard.
At completion of the day, Gray has actually been looking for a constant variation of a fastball for much of the year, however I do not totally get why he would restrict the use of his slider, which has actually been his finest pitch this season.
Cristopher Sanchez – Philadelphia Phillies
Another pitcher who has actually made modifications to their pitch mix that have actually not yet caused outcomes is Cristopher Sanchez , who has actually reduced the use of his sinker while increasing both the usage and motion on his slider.
Yet, August has actually likewise been his worst month with a 4.70 AGE (5.43 dERA) throughout 23 innings after publishing a 2.40 AGE (3.61 dERA) in June and a 2.25 AGE (2.26 dERA) in July. Still, I’m not excessively worried about the bad outcomes.
On one hand, a few of it is natural regression. Sanchez was not going to be a 2.40 period pitcher for the rest of the season. He has actually likewise begun to see his sinker get struck harder with a 6.89 dERA and 14.8% barrel rate. However, we likewise see that he’s restricting the use of that pitch, so he comprehends that it’s not his finest offering.
What intrigues me is that Sanchez has actually included motion to his slider, as you can see from this Brooks Baseball chart of vertical motion listed below.
He has actually likewise seen a big dive in SwStr% from 9.2% in July to 17.6% in August. Now, Sanchez has actually done this in June too, however that likewise caused an 18% SwStr% on the pitch and among his finest months. I believe the included motion is a net favorable for Sanchez, and we have previous outcomes to bear that out, so I believe we’ll begin to see the production follow. I’d still be holding where I could.
