【Three Core Types of Foul Balls】Foul Ball Rules

1️⃣ Ground Foul | Ground Foul

The ball lands outside the first/third base (⚠️ The vertical line of the base serves as the boundary!)

Umpire signal: One arm pointing at the touching point ✋

MLB Rule 5.05(a)(2): "batted ball settling on foul territory"

2️⃣ Touching Foul Object | Touching Foul Object

⚾ If the ball hits the following objects, it is immediately ruled dead:

Outfield fences/advertising boards

Spectators/umpires in foul territory

Roofs (e.g., Tropicana Field, home of the Rays)

Umpire action: One hand pointing to the contact point ️

3️⃣ Fly Ball Over Foul Territory | Fly Ball Over Foul Territory

️ The ball flies over the foul fence/pole without touching the ground

️ Important! If it does not touch the ground = dead ball; if it bounces out after hitting the ground = live ball

⚠️ 【Controversial Call Logic】Umpire's Decision

Foul Tip | FOUL TIP

The ball lightly touches the bat and goes directly into the catcher's glove (height ≤ batter's head)

✅ Counts as a strike! The catcher must secure the catch

If not caught → regular foul ball

Rule 2.0: "Foul tip is a LIVE BALL"

Foot Out of Box | Foot Out of Box

‼️ Rule 6.03(a) Note:

If the entire foot steps out of the batter's box while hitting

Even if the ball flies into fair territory → it is ruled a foul!

Umpire signal: Hand slapping knee + pointing to the batter's box ❌

【Impact of Foul Balls】Game-Changing Impact

✨ During the first two strikes → +1 strike (increasing pressure on the batter)

The third strike being a foul tip → does not count as a strikeout! Runners can steal bases ♂️

Failed bunt that goes foul → results in an immediate strikeout! All players must stop on their bases
