Classification — cricket terms: identify the word that does NOT belong with standard cricketing positions/deliveries.

Introduction / Context:
Sports-terminology classification checks whether a term is a recognized fielding position or bowling delivery. Three of these are mainstream in cricket contexts; one is not a standard standalone term.

Given Data / Assumptions:

• Slip → standard fielding position.
• Googli → common misspelling of “googly,” a leg-spinner’s deceptive delivery; treated as the same in reasoning sets.
• Doosra → off-spinner’s delivery turning opposite to the conventional off-break.
• Diamond → not a standard position/delivery name by itself; “diamond duck” exists, but “diamond” alone is not the role/delivery label.

Concept / Approach:
Accept conventional cricket vocabulary and typical reasoning-set tolerance for minor spelling (googli→googly). Flag terms that only appear as part of a multiword phrase (e.g., diamond duck) rather than as a canonical role/delivery.

Step-by-Step Solution:
1) Slip → valid fielding position.2) Googli → accepted for “googly,” valid delivery.3) Doosra → valid delivery.4) Diamond → no standard cricketing role/delivery on its own.

Verification / Alternative check:
Cross-check standard lists of positions and bowling types—“diamond” appears only in phrases like “diamond duck,” not as a position/delivery.

Why Other Options Are Wrong:
They are recognized cricketing terms and fit the group.

Common Pitfalls:
Rejecting “googli” due to spelling; these questions typically accept common variants intended to denote “googly”.

Final Answer:
Diamond
