Gear by position

Infield: second base, shortstop, third base

What's different: a smaller glove with a shallow pocket, so she can get the ball out fast for quick throws. Common webs are the I-web and H-web, which let dirt fall through.

Many infielders wear a fielder's face mask, and some leagues require one.

Outfield

What's different: a longer glove with a deeper pocket, for reaching fly balls and holding on during running catches. Common webs are the trapeze and H-web, which make a deep pocket and let her see the ball through the web.

Utility: plays more than one spot

What's different: a glove in between infield and outfield size. It's the best first glove for a player who moves around or hasn't settled on a position.

Pitcher

What's different: a closed web, so the batter can't see her grip and guess the pitch. Gloves can't be the color of the ball or have markings that look like one, and umpires check pitchers most closely.

Pitchers are the closest fielder to the batter, so most wear a face mask. They also drag their back toe on every pitch, so a toe guard helps cleats last.

First base

What's different: a first base mitt instead of a glove. It has no separate fingers and a long, scoop-shaped edge for picking low throws out of the dirt.

A player who plays first only now and then can use her regular glove. See Starting a new position if she's moving there full time.

Catcher

What's different: everything. Catchers need a catcher's mitt, which is heavily padded and measured around the outside, plus a full set of gear: helmet with throat guard, chest protector, and leg guards.

See Catcher's gear for chest protector and leg guard sizes.
