Are metal cleats, jewelry and mismatched uniforms allowed?

Under Rule 3, Section 6:

Shoes:

• Metal cleats are allowed in 14U fastpitch. The no-metal rule applies only to JO fastpitch 10U and 12U, JO slow pitch, and coed and senior slow pitch.
• Cleats on metal sole or heel plates can't stick out more than 3/4 inch. Round metal spikes are illegal.
• Detachable cleats that screw into the shoe are legal. Screw-on cleats are not.

Jewelry: exposed jewelry the umpire judges dangerous must come off. Medical alert bracelets or necklaces aren't jewelry, but must be taped to the body with the information still visible.

Uniforms:

• Players' uniforms must match in color and style, with a whole number from 0 to 99, at least 3 inches high, in a contrasting color. No two players may wear the same number, and a player without a number can't play.
• Caps, visors and headbands are optional for girls and may be mixed. Handkerchiefs and plastic visors aren't allowed.
• Pants may be long or short. If more than one player wears undershirts or sliding pants showing, they must match.
• Casts, splints and braces with hard surfaces must be padded.

A player who refuses to remove jewelry, illegal shoes or illegal uniform parts can't play.
