R Sai Kishore revealed the one variable in spin bowling that no batsman can ever detect: grip pressure. In a detailed spin bowling masterclass on YouTube, the Gujarat Titans and Tamil Nadu left-arm spinner explained that while a batsman can study a spinner’s hand position, seam orientation, and wrist angle, there is no way to gauge how tightly or loosely the bowler is holding the ball.
“A batsman can see how you’re holding it, but he can’t see the pressure. So he cannot see how tight I’m holding it or how loose I’m holding it… if I hold it a little more loose, I can’t spin the ball. There is no friction on the ball. The batsman can never tell.”

Grip pressure determines friction between the fingers and the ball. More friction means more revolutions. Less friction means the ball slides out without bite. Every other element of a spinner’s release, the position of the wrist, the angle of the seam, the trajectory of the arm, is visible to a batsman watching from 22 yards. Grip pressure is not. It is a problem that batsmen have faced against every great spinner, and Matt Prior once described just how difficult it was to pick Muralitharan’s variations even from behind the stumps.
Sai Kishore’s disclosure carries weight because of who he is and how he bowls. Standing six foot three, the 29-year-old uses his height and long fingers to generate both spin and overspin. He idolises R Ashwin so deeply that he wears jersey number 99, mirroring Ashwin’s own. Hardik Pandya, who captained him for two seasons at Gujarat Titans, called him a “scientist” for his ability to out-think batsmen rather than simply out-spin them.
That description fits. After IPL 2024, Sai Kishore studied ball-by-ball Hawk-Eye data from his own season, analysing pitch maps and release points. One result of that study was the refinement of a carrom ball, a delivery almost unheard of from left-arm spinners. Only Mitchell Santner among active left-arm bowlers worldwide was bowling it regularly. In IPL 2025, Sai Kishore used it to dismiss Krunal Pandya, turning the ball away from the left-hander when conventional left-arm spin would have turned in. He finished IPL 2025 with 19 wickets in 15 matches at an average of 20.68, the second-highest wicket tally among spinners that season.
Why Grip Pressure Changes Everything for a Left-Arm Spinner
The masterclass quote is not an offhand remark. It reflects a deliberate philosophy Sai Kishore has built over years. He once told Sportskeeda that he does not want to bowl the carrom ball and googly just to create a perception that he has variations. Every addition to his repertoire serves a specific tactical function, and the grip pressure principle is the thread running through all of them.
Spinning the ball hard requires a firm grip. Bowling it at pace requires a fluid release. These two demands pull in opposite directions, and the resolution lives entirely in how a bowler distributes pressure across the fingers. Too tight and the arm stiffens, which slows the delivery and alerts the batsman. Too loose and the ball loses revolutions.
What makes Sai Kishore’s explanation significant is that he frames grip pressure not as a technical detail but as a tactical weapon. The batsman sees the same hand, the same seam, the same arm speed. The ball either rips or slides, and the batsman gets no advance warning.
This is the logic behind the carrom ball’s late addition to his arsenal. He told ESPNcricinfo that he had been practising the delivery for three to four years before feeling confident enough to bowl it in IPL 2025. The carrom ball requires a fundamentally different finger pressure: the ball is flicked out from between the thumb and middle finger rather than rolled off the index finger. Yet the hand shape at the point of release can look almost identical to a conventional delivery. The deception, again, is in the pressure, not the position. The kind of craft that is rarely shared openly between spinner and coach, let alone on a public platform.
Former India batting coach Sanjay Bangar compared Sai Kishore’s control over speeds and angles to Daniel Vettori and Mitchell Santner. Aakash Chopra noted that his carrom ball could change how captains use left-arm spinners against left-handed batsmen entirely, a situation where orthodox left-arm spin has traditionally been considered a liability.
Sai Kishore’s red-ball credentials underline the point. He has taken 192 first-class wickets at an average of 23.51, captaining Tamil Nadu to three consecutive outright Ranji Trophy wins for the first time since 2015. In July 2025, he signed a short stint with Surrey in the County Championship, taking a five-wicket haul against Durham in only his second match. The versatility echoes what Garry Sobers achieved with three distinct bowling styles, though Sai Kishore’s range operates within the subtler margins of finger spin. His first-class record proves that the grip pressure principle is not a white-ball trick. It is the foundation of his bowling across formats.

The detail Sai Kishore shared about grip pressure opens a door that most commentary never walks through: what happens to that grip when conditions change.
A new red ball with a pronounced seam gives a spinner a natural ridge to grip against. The fingers lock into the seam and the friction is built into the equipment. Forty overs later, that seam has flattened. The lacquer is gone. The surface of the ball is smoother. To generate the same revolutions from the same delivery, the spinner has to grip tighter.
But tighter grip creates a problem. It stiffens the wrist and slows the arm. A batsman who has faced 20 overs of the same bowler will pick up any change in arm speed instantly. That slight deceleration before a turning delivery becomes a cue, and the batsman adjusts. The element of surprise, the very thing Sai Kishore describes as the advantage of invisible pressure, disappears.
The professional adjustment is subtler than simply squeezing harder. It is about redistributing pressure across different fingers without changing the total force. Instead of gripping tighter with the entire hand, a spinner might press harder with the index finger and ease off with the ring finger, or shift the point of contact slightly along the seam. The hand looks the same. The arm speed stays the same. But the ball behaves differently because the friction point has moved.
This is also why the same spinner produces different amounts of turn on different grounds and in different sessions of play, even when the pitch itself has not changed much. The ball is ageing, and the spinner is making micro-adjustments to grip that no camera, no analyst, and no batsman can detect. It is the most instinctive part of spin bowling, learned through thousands of overs, and Sai Kishore is one of the few active players to describe it publicly.
