Baseball is a game of precision and strategy, where a single pitch can make all the difference in the outcome of a game. In recent years, the rise of advanced analytics and pitch tracking data has given fans and coaches unprecedented insight into the performance of individual players.
One player who has received particular attention in this area is Dylan Cease, a promising young pitcher for the Chicago White Sox.
By analyzing the pitch tracking data collected by the PITCHf/x system, we can gain a better understanding of Cease’s pitch repertoire and evaluate his performance on the mound.
We’ll take a closer look at how many pitches Dylan Cease has thrown, which pitches he relies on most, and how effective they have been in the 2019-2023 seasons.
How Pitch Tracking Data is Collected
Pitchf/x System
The PITCHf/x system is a sophisticated pitch-tracking technology used by Major League Baseball to capture data on each pitch thrown during a game.
The system was developed by Sportvision in partnership with MLB Advanced Media and uses a combination of high-speed cameras and radar to track the movement of the ball from the moment it leaves the pitcher’s hand to the point where it crosses the plate.
The system captures a wide range of data, including pitch type, velocity, spin rate, and release point.
How Data is Captured
The PITCHf/x system works by using two high-speed cameras, one behind home plate and one at a higher angle above the field, to track the ball’s trajectory.
These cameras capture images of the ball at a rate of 60 frames per second, allowing the system to measure the exact speed, spin, and movement of the pitch. In addition to the cameras, the system also uses radar to measure the speed and location of the ball in flight.
By combining data from both the cameras and radar, the PITCHf/x system is able to provide a highly accurate and detailed picture of each pitch.
Limitations of the System
While the PITCHf/x system is a powerful tool for analyzing pitcher performance, there are some limitations to the data it provides.
One limitation is that the system relies on cameras and radar to track the ball’s movement, which means that pitches that are obscured or thrown off-camera may not be accurately recorded.
Additionally, the system may occasionally misclassify pitches or misattribute them to the wrong pitcher.
Finally, while the PITCHf/x system provides a wealth of information on each pitch, it does not capture other important factors that can affect a pitcher’s performance, such as the batter’s stance or the game situation.
Despite these limitations, the PITCHf/x system remains an essential tool for analyzing pitcher performance and understanding the nuances of the game.
Analysis of Dylan Cease’s Pitch Repertoire
Total Number of Pitches Thrown
According to PITCHf/x data, Dylan Cease has thrown a total of 8,854 pitches between 2019 and 2023. This includes pitches thrown in both regular season games and spring training.
Breakdown of Pitches Thrown by Type and Frequency
Of those 8,854 pitches, Cease’s pitch repertoire has primarily consisted of three types of pitches in the 2023 season: Slider, Fourseam Fastball, and Curve. The frequency and distribution of these pitches are as follows:
Slider: Cease has thrown 3,290 sliders, accounting for 37.1% of his total pitches in 2023. The average velocity of his slider is 87 mph.
Fourseam Fastball: Cease has thrown 2,793 four-seam fastballs, making up 31.5% of his total pitches in 2023. The average velocity of his four-seam fastball is 96 mph.
Curve: Cease has thrown 1,145 curves, representing 12.9% of his total pitches in 2023. The average velocity of his curveball is 80 mph.
In addition to these three primary pitches, Cease has also thrown a smaller number of other pitch types, including a Changeup and a Cutter, among others.
Comparison to League Averages
Compared to league averages, Cease relies more heavily on his Slider and Fourseam Fastball, while throwing fewer Changeups and Sinker pitches.
According to Statcast data, the average pitcher in the MLB throws a fastball 52.8% of the time, while Cease throws his fastball only 31.5% of the time. Similarly, the average pitcher throws a slider 18.8% of the time, while Cease throws his slider 37.1% of the time.
These differences suggest that Cease has developed a unique pitch repertoire that allows him to keep hitters off balance and generate swings and misses.
Evaluation of Dylan Cease’s Performance
Effectiveness of Each Pitch Type
To evaluate the effectiveness of each of Dylan Cease’s pitch types, we can look at a number of metrics, including swing-and-miss rate, called-strike rate, and opponents’ batting average against each pitch type.
According to Statcast data, Cease’s Slider has been his most effective pitch in 2023, generating a swing-and-miss rate of 35.8% and a called-strike rate of 15.7%. His Fourseam Fastball has also been effective, with a swing-and-miss rate of 24.4% and a called-strike rate of 9.3%.
His Curveball, while thrown less frequently, has also been an effective pitch, with a swing-and-miss rate of 29.9% and a called-strike rate of 15.4%.
Changes in Pitch Usage Over Time
Looking at changes in pitch usage over time can provide insight into how Cease has evolved as a pitcher. In the 2023 season, Cease has relied more heavily on his Slider and Curveball, while reducing his usage of his Fourseam Fastball.
This represents a shift from his pitch usage in previous seasons, where he relied more heavily on his Fourseam Fastball and Changeup. This change in pitch usage may reflect a strategy to keep hitters off balance and generate more swings and misses.
Comparison to Previous Seasons and Other Players
To compare Cease’s performance to previous seasons, we can look at a number of metrics, including ERA, strikeout rate, and walk rate. In 2023, Cease has posted an ERA of 3.02 through his first five starts, a significant improvement from his 2022 ERA of 4.82.
His strikeout rate in 2023 is also up to 28.1%, compared to 25.5% in 2022. However, his walk rate has also increased slightly, from 8.5% in 2022 to 9.5% in 2023.
To compare Cease’s performance to other players, we can use advanced metrics like FIP (fielding independent pitching) and xFIP (expected FIP). According to Statcast data, Cease’s 2023 FIP is 3.19, which is above average but not elite.
