Illegal Glove

[Dakota]

F3 playing in - near the start of the running lane.
F4 comes over to cover first on a bunt.
F9 playing in to cover the slap.

Since all three are for all practical purposes covering the area normally covered by F3, I say all three may legally wear a mitt. The dugout has an official "glove runner" who runs the proper gloves in and out of the game between pitches.
