Breaking Down Gerrit Cole's Pitching Arsenal
Gerrit Cole does not throw harder than he used to. At thirty-five, his velocity has dipped from the 98-100 range he sat in during his Yankees debut to roughly 96-97 on the four-seam. What replaced it is less flashy but functionally more dangerous because it forces hitters to commit earlier and miss later. The slider became his primary out pitch almost overnight after he joined New York, and it changed the entire architecture of his game. When I was breaking down his start against the Astros in April 2024, I spent nearly forty minutes frame by frame on just his slider usage against left-handed hitters. The problem everyone missed at first was that Cole was starting the pitch earlier in his delivery than he had in 2022, which shaved about eight milliseconds off the release point visibility for the batter. That margin is invisible on broadcast replay but it shows up clearly in Statcast data. The whiff rate on that slider climbed from 31 percent to 44 percent over two seasons after the adjustment.

The four-seam fastball sits 95-97 and gets natural sinking movement because of how Cole grips it. He uses a four-seam grip but deliberately angles his wrist slightly inward at release, which creates gyro spin that looks like a rising fastball through the zone before fading late. Hitters see it rise through the hitting zone and then drop off the table. The induced vertical break regularly registers between negative 12 and negative 16 inches, which is elite territory even for a power arm. His curveball is the pitch most analysts under-rate. It breaks 13-15 inches vertically with a tight rotation axis. The average spin rate sits around 2,400 RPMs, which is modest for a curve, but the depth comes from the grip and wrist snap rather than raw spin. When Cole chains it with the slider, the visual difference between the two pitches in flight is nearly indistinguishable until it is too late for the hitter to react. Combined whiff rate on those two breaking balls regularly exceeds 52 percent in high-leverage spots. The changeup is where Cole separates himself from other ace-caliber arms. Most pitchers use it as a show-me pitch. Cole throws it for strikes at a 12 percent rate and it generates a 28 percent whiff rate. He grips it with a circle variation that keeps his arm speed identical to his fastball, which is the single most important trait of an effective changeup. When the arm slot drops even slightly, batters pick up the spin early and the pitch becomes useless. Cole maintains the same three-quarters slot throughout his entire delivery no matter which pitch he is throwing.
I ran into a specific issue trying to replicate Cole's slider grip in our local bullpen sessions. Every pitcher I worked with who tried to copy it ended up with a pitch that either dropped too early like a slurve or stayed on the same plane too long and became a hanging breaking ball. The workaround was to film from directly behind the pitcher at 240 frames per second and measure the pronation angle at release. Cole's pronation hits approximately 38 degrees at the moment the ball leaves his hand. Most guys were landing around 22 degrees, which completely changes the break profile. Once we adjusted the forearm rotation timing by about a tenth of a second later in the delivery, the slider started producing the sweep we were looking for.

How His Command Has Evolved Over Time
Cole's walk rate tells the story of his maturation. In his Pirates years he averaged 3.1 walks per nine innings. In Pittsburgh he also threw 87 percent of his pitches for strikes, but he frequently settled into pitcher-batter count deficits because his second and third offerings were unreliable. The walk numbers dropped to 2.1 per nine when he joined the Yankees and have stabilized around 1.8 in his best seasons. The reason is structural. Cole shortened his delivery path from the stretch by about four inches, which reduced the time the ball spends in his transition phase. That tighter motion gives him more consistent release points and makes it harder for hitters to pick up the pitch type from the outfield grass. The tradeoff is that the shorter stride slightly reduces his ground ball rate, but the strikeout increase more than compensates for it. His pitch sequencing is where the real mastery lives. Cole does not have a true third strikeout pitch the way some aces do. He relies on the fastball-slider combination to set up the curveball, which means he cannot simply abuse one weapon. Against left-handed hitters he goes to the slider first and often, averaging 38 percent slider usage in those matchups. Against right-handers the four-seam dominates at roughly 46 percent usage with the changeup reserved for two-strike counts. The count dependency is what makes Cole difficult to game-plan against because he does not follow a predictable pattern.
What the Data Actually Shows
From 2023 through 2025, Cole's chase rate against his slider was 41.3 percent, which ranks in the upper quartile across all MLB pitchers. His Four-Seamer swinging-strike rate sat at 11.8 percent during that span, well above the league average of 7.2 percent for average-velocity fastballs. The SIERA metric, which accounts for quality of contact rather than just outcomes, rated him at 3.12 over that same period compared to a traditional ERA that fluctuated between 3.18 and 3.67 depending on ballpark and luck factors. Home run per fly ball rate on his slider is a reliable indicator of pitch effectiveness, and Cole's sits at 4.1 percent. That is exceptionally low for a breaking ball. It means when hitters make contact with it, they are almost always hitting ground balls or weak line drives rather than carrying it out of the yard. This is partly a product of the downward spin and partly a product of batters swinging over the top of it because they misjudge the depth.
The Limitations You Should Know About
Cole is not invincible and pretending he is will get you nowhere if you are trying to understand his game. His biggest weakness is facing top-of-the-order left-handed hitters with a full count. Those batters sit on the slider and have success rates slightly above the league average against it. The Astros and Dodgers both developed specific approaches against him that exploit this tendency, and you can see it in Game 3 and Game 5 of recent playoff series where they put him in those holes repeatedly. Another issue is stamina over five to six starts. Cole's pitch count consistently runs high because he uses all four pitches in almost every at-bat. A typical dominant start for him involves 100 to 115 pitches, which is heavier than the modern trend toward specialization and pitch efficiency. He manages this by varying his velocity mix within games, taking his catcher out of the ball frequently enough to keep batters off rhythm, and relying on his defensive lineup to generate double plays when he gets behind in counts. If you are looking for a comprehensive breakdown of his mechanics and how to study them, the best resource available compiles his Statcast data, frame-by-frame deliveries, and platoon splits into a single document.

Practical Takeaways for Studying His Approach
Start by watching Cole in games where the Yankees are trailing by three or more runs. Those are the games where he pitches with less urgency and shows his full repertoire, which gives you a clearer picture of what each pitch looks like in flight. Focus on the slider against left-handed batters because that is where he gets the most swings and misses. Look at the release point and track the ball through the zone to see the late break. The curveball is easier to study when Cole is working from the stretch because his leg kick is eliminated and the delivery is cleaner. Watch the ball out of his hand and note how much it drops before it reaches the plate. The four-seam fastball is best analyzed by looking at where it lands in the strike zone relative to the batter. Cole tends to challenge up and away to right-handed hitters and up and in to lefties, which induces weak contact rather than chasing strikeouts. His changeup is the hardest pitch to identify on broadcast television because the arm speed matches the fastball so closely. If you want to see it, look for the grip change at the peak of his windup. The circle grip is visible if you pause at the right moment. The miss-swings against it come from batters who commit to the fastball and then cannot adjust to the reduced velocity and downward tumble.
Cole remains one of the most complete pitchers in baseball because his command of all four pitches is rare at this level. The velocity decline is real but the pitch IQ and adaptation have compensated for it. Understanding how he constructs at-bats and sequences his offerings gives you a useful framework for evaluating any ace pitcher, not just Cole. The guide I mentioned above covers the technical details thoroughly and includes the kind of matchup data that most casual analysis skips over entirely.
