InfieldBy rule a 90-foot square. Home plate and the three bases are at its corners. In everyday talk the name also takes in the ground just outside the square.
OutfieldFair ground from the infield out to the fence.
Pitcher's moundThe pitcher throws from the slab on top. The slab is called the pitcher's plate or the rubber.
First baseA square bag fixed to the ground. It sits wholly inside the infield.
Second baseThe bag is centered on its corner of the square. It is on the line from home plate through the pitcher's mound.
Third baseA square bag like the other two. It sits wholly inside the infield.
Foul lineThe lines run past first base and third base. The ground between them, lines included, is fair territory; everything outside is foul territory.
Foul poleIt carries the foul line upward. Then an umpire can judge a high fly ball. A fly ball that hits the pole is a home run.
Outfield fenceAlso called the outfield wall. A fair ball that flies over it without touching the ground is a home run.
Warning trackIt feels different from grass underfoot. A fielder watching a fly ball can then tell that the fence is near.
BullpenIts place depends on the ballpark. It lies in foul ground along a baseline or, as drawn here, just beyond the outfield fence.
Coach's boxThe first base coach and the third base coach stand in them.
DugoutThe rule book asks for one bench for each team. Roofed and closed in at the back and the ends.
StandsThe seating around the field. Only the part that wraps the infield is drawn here.

How it works
This blank map of a baseball field is the whole field from above on one sheet, with no names and no numbers. Fourteen parts wait for a name, from the infield and its three bases out to the fence and the bullpens.

The fourteen names in number order
Infield, outfield, pitcher's mound, first base, second base, third base, foul line, foul pole, outfield fence, warning track, bullpen, coach's box, dugout, stands. Home plate, the batter's boxes, the on-deck circles and the backstop are drawn small at the bottom corner and carry no number here; the labeled baseball field enlarges and names them.
Parts that get swapped on a blank field
The outfield fence is the outer edge; the warning track is the band just inside it. The bullpens are the two small areas beyond the fence; the dugouts are the long blocks set into the stands, one on each side of the infield. The pitcher's mound is the round patch in the middle of the infield; the two small circles near home plate are on-deck circles.
For a younger class, ask for the first six names only: infield, outfield, pitcher's mound and the three bases.
Five parts are drawn twice, and one name covers each pair: foul line, foul pole, bullpen, coach's box and dugout.
The field is not to scale: the infield and bases are drawn larger than life. It suits naming parts or penciling in fielders, not measuring.
Questions and answers
How many bases are on a baseball field?
Four: first base, second base, third base and home plate, which the rule book calls home base. The three bags are numbered parts of this sheet. Home plate is at the bottom corner, where the two foul lines start.
What is the dirt in front of the outfield fence called?
The warning track. It feels different from grass underfoot, so a fielder with eyes on a fly ball can tell that the fence is close.
Where is the on-deck circle on a baseball field?
In foul ground between home plate and a team's bench, one circle for each team. The next batter warms up there. The rule book's own name for it is the next batter's box.
Does the blank baseball field come with an answer key?
Yes. The key is this field with all fourteen names written on it. The numbered copy has a key of its own, with each name on its line under the drawing.
