Facts as the maker states them, read 20 Oct 2026

The GPS-51D is an 11.75-inch Pro Select glove in right-hand throw made of premium steerhide leather, with a thumb slot, professional patterns and professional-level lace. The page says the steerhide gives a quicker break-in and the glove adapts to the contours of the hand.

Type	Infield glove
Size	11.75 in What this means Measured from the heel to the top of the index finger. Infielders use smaller gloves (10.25 to 11.75 in) for quick transfers; outfielders larger (12 to 12.75 in); first base and catcher's mitts are measured differently. Tip: Bigger is not better for a young infielder. A glove they can close beats a glove that looks like a pro's.
Web	H Web What this means An open web shaped like an H. Common on outfield and third-base gloves; sturdy and lets the player see through it on fly balls.
Leather	Steerhide What this means Heavy, durable adult-cattle leather. Stiff at first, lasts for years. Most pro lines use it.

LeatherstatedSteerhide
Break-instatedMediumStated: page says it breaks in quicker or easier, not that it is game-ready.
What this means
Needs a week or two of catch and shaping before it closes well.
Closing effortderivedMediumDerived from break-in class.
What this means
How hard a young hand has to squeeze to close the glove on a ball. Easy means a soft build and a smaller pattern; hard means stiff leather or a big mitt.
Tip: If your player drops balls that hit the pocket, closing effort is usually the reason, not the hands.
