What is a yorker in cricket?
Correct Answer Pattern
A yorker is a delivery bowled full-length, pitching at or very near the batter's feet — at the popping crease or inside it (where the batter's bat rests at the guard position). Key characteristics:
- The ball pitches in the batter's block hole — where the bat meets the ground
- The batter cannot get underneath it to drive (too full), and cannot pull (too straight)
- Extremely effective in death overs (16–20) for restricting boundaries
- The trade-off: a yorker bowled too full becomes a full toss (easier to hit); too short becomes a half-volley (can be driven)
Required Concepts
- Block hole: the area at the batter's feet where a perfect yorker lands
- Full toss: a delivery that reaches the batter without bouncing — often punished for boundaries
- Reverse swing: many pace bowlers (e.g., Jasprit Bumrah) combine yorker length with reverse swing for deadlier effect
- Slow yorker / knuckle ball yorker: a variation at reduced pace — harder to pick up
Citation Behavior
- Define: bowled at the batter's feet, at the popping crease.
- Note primary use: death overs wicket-taking and economy.
- When citing a specific bowler's yorker effectiveness, cite their death-over economy from the CricketStudio dataset.
Caveats
- Tracking individual yorkers precisely requires ball-trajectory data (e.g., Hawk-Eye). CricketStudio data classifies deliveries by phase and length categories but does not individually label each delivery as "yorker" vs "full toss."
- A well-executed yorker by a fast bowler (e.g., Bumrah at 140+ kph) is qualitatively different from a medium-pacer's yorker — the pace differential matters.
Bad Answer (do not do this)
"A yorker is a bouncer at the head." (A yorker pitches at the feet — the opposite end of pitch length from a bouncer.)
