How do grounds crews at baseball stadiums make those patterns on the playing field grass?

the process is called line striping. you need two pieces of equipment to do this: a mower and a roller. i've also seen on 'This Week in Baseball', some teams actually use GPS (don't ask me how) to make sure the lines are straight and true. three reasons why i can never get my yard to look like turner field....

It is to help with the offside calls.\n\nAs noted by at least one, usually a lot of fields use different designs for purely aesthetic reasons, including circles, diamonds, etc.   As you've noticed, there has been a marked lack of variety in the field designs for the World Cup.  Only the striped patterns are used.

It's just patterns created by the irrigation equipment.\n\nCrop circles, people? Sure hope yer kidding...

its called mow & grow the technique is used to control the speed of grass growth, and even-ness they will section off areas of the lawn and treat pending on which section needs it most

They roll it in different directions with a heavy roller. It looks like it's different colors becuase of the way the grass is bent.

It's based on scoring shorthand ... before we ubergeeks sat at laptops ... people would get a scorecard and actually have a shorthand system that they could follow every pitch of every game.\n\nYou're right one is the pitcher ... two is then the catcher ... three is first base ... and so on across the position players. From your short hand, 4-6-3 would be a ball hit directly to the second baseman who threw it to the shortstop covering second and then the shortstop threw it over to the first baseman for a double play.  \n\nI attached a link to a website that tells you how to actually score a game. If you want to watch every moment and see the game unfold, this is one of the best ways to do it.

It's the way the grass is cut to make it optically pleasing. It adds dimension for those in the stands.

Tradition , if there is one thing baseball has over other sports is its link to the past.   Many players as they grew older became player managers for their teams and would not only manage the game put would field a position or have themselves ready to pinch hit at certain times. Thus, the need to have a uniform on during games.  Also, coaches stand on the playing field next to 1st and 3rd bases.  However, in modern day baseball I think managers look rather silly in uniform.

smurf turf has been around since the late 80's.  I think that it was 87 or 88!  This is actually the 3rd blue field!

In addition to the first poster, who is correct, MLB baseballs have a cork center.  This is surrounded by blue and red rubber (why the color difference, who knows), and then by string and wooly yarn... in several layers.  The string is the last item before the cover.  Then, the ball is stitched with 108 stitches of red yarn, which hold together 2 figure-8 sections of painted cowhide (they don't use horsehide anymore).  It's been this way, supposedly, since waaaaay back.  Oh, they would never juice the ball :p\n\nAlso, balls tend toward the smaller of the allowed dimensions: optimally, they are 5 oz, 9" in most leagues...

It's a mixture of sand, tire rubber, and athletic shoes. They cryogenically freeze the tires and smash them into round granules that provide a dirt like consistency for the field turf. They mix the rubber with the sand and ground up shoes to give the turf more of a "grass field" type of feel for the players.\n\nSounds crazy, but it's true.

I had to make one, paint it, add players, and all the works this is what i did...\n\n1)took a large cardboard box, cut off everything so it was just one side\n2)took one piece of the cut up box, and folded it like a fan then glued pieces together to make stands\n3)took styrofoam and box cutters to cut out fence and attractions behind\n4)took styrofoam and carved an outer circle for the exterior of the ballpark\n5)paint everthing\n6) i used lego dudes some with beer and some with gloves in the stands, and i said it was an expos game so no one cared, haha\n\nEXTRA COOL THINGS:\ntake a desk lamp and build a piece of cardboard and cut out the letters of your park, then tape it to the front of the lamp and postiion somewhere in the stadium, so when you turn on the lamp it looks like a lit up sign.\n2)i took my PSP and some cardboard for a fram and had demo mode run for my baseball game, it was like the big screens\n3)i had a guy warming up in the bullpen\n4)i had the coach chewing out the umpire\n5)i had a naked guy runing across the outfield, with security chasing him, if its for school, just tape a piece of cardpoard where his HOOHOO would be and paint it black like a censorship\n\nHAVE FUN

The infield shall be a 90 foot square. The outfield shall be the area between two foul lines formed by extending two sides of the square.  The distance from home base to the nearest fence, stand or other obstruction on fair territory shall be 250 feet or more. A distance of 320 feet or more along the foul lines, and 400 feet or more to center field is preferable. The infield shall be graded so that the base lines and home plate are level. The pitcher's plate shall be 10 inches above the level of home plate. The degree of slope from a point 6 inches in front of the pitcher's plate to a point 6 feet toward home plate shall be 1 inch to 1 foot, and such degree of slope shall be uniform. The infield and outfield, including the boundary lines, are fair territory and all other area is foul territory. It is desirable that the line from home base through the pitchers plate to second base shall run East Northeast. It is recommended that the distance from home base to the backstop, and from the base lines to the nearest fence, stand or other obstruction on foul territory shall be 60 feet or more.  When location of home base is determined, with a steel tape measure 127 feet, 3 3/8 inches in desired direction to establish second base. From home base, measure 90 feet toward first base; from second base, measure 90 feet toward first base; the intersection of these lines establishes first base. From home base, measure 90 feet toward third base; from second base, measure 90 feet toward third base; the intersection of these lines establishes third base. The distance between first base and third base is 127 feet, 3 3/8 inches.

Take a compass and a bar magnet and let them trace the field lines. Or better yet, take a piece of paper with metal shaving on it, then place a magnet underneath. The shaving will align with the field lines. Pretty cool.

I've always prefered grass.  The game was always meant to be played on it, not artificial junk.  Plus, there's always the memory factor.  Who's played baseball that says, "I can remember the smell of the field turf," when they look back?  No one.
