What is the ruling when a batter hits a stand-up double with his foot on the inside line of the batter's box and on home plate?

• A. The hit stands; the batter stays on second base.
• B. The batter is out.
• C. The batter must replay the at-bat.
• D. The batter is ejected.

Answer: (A)

The key idea is that being in the batter’s box allows some contact with its edges, and the lines count as part of the box. If a batter has a foot on the inside line of the batter’s box, that foot is still inside the box. Touching home plate with a foot at that moment doesn’t make the stance illegal. Because the ball is in play and the batter makes contact to produce a stand-up double, the hit stands and the batter ends up on second base. No rule is violated by the stance in this scenario, so there’s no out, no replay, and no ejection.
