Where baseball gets technical
- Force plays and appeals: when the force is still on, when it disappears, and how missed-base or leaving-early appeals change an inning.
- Interference and obstruction: who owns the running lane, when a fielder is protected, and how umpires award bases after illegal contact or blocking.
- Balks, dead balls, and awards: what stops play immediately, what stays live, and how runners are placed after the violation.
