What are those two dirt circles for just to the left and right of the infield by the home plate area?

Those are probably the fungo circles.  When teams are taking their fielding practice, coaches hit fly balls to outfielders using a fungo bat.  By dedicating a dirt patch for that, it helps prevent wear and tear on the grass.

Q: Why is the foul pole called the foul pole when it is actually in fair territory?\n\nA: Good question. Contrary to common knowledge, the foul pole was named over something having nothing to do with the ball being in play or not. When the early designers of stadiums put these unnamed (at this point) poles up to help make calls on deep drives, they often became perches for area ducks and geese who found the lofty location a great way to spot food sources below. It wasn't long before these home run honkers started becoming a menace by leaving their calling cards on unprotected outfielders. Although stadium owners eventually hired sharpshooters to scatter the unwanted visitors, the nature of their specimen and the odor they left behind made "fowl" pole a perfect fit (The spelling was later changed to "foul").\n\nhttp://www.whitecaps-baseball.com/PRESSBOX/FEATURE2000/berkey2.html

Someone that throws left-handed. It came from the notion that when a left handed pitcher was on the mound he faced "south" before delivering a pitch as most parks were designed with home being "west" and second base positioned "east" for sunlight/fielding purposes

Home plate began its baseball career in the nineteenth century as a twelve-inch square, set down like a diamond, with the two sides forming the beginning of the foul lines. Home is the compass by which a baseball field is set. Those foul lines extend up the foul poles and on into infinity. It's the diamond of home plate that starts them running. In the winter of 1899 the Rules Committee extended the bottom of the plate (that is, the side facing the pitcher), creating the foundation of the home plate pentagon/house. That year's Spalding Guide tells us the committee felt the pitcher was handicapped by having to "cut the corners" of the old twelve-inch square. The umpire also found it difficult to judge which pitched balls caught those corners. The guide adds that by making the front of the plate square with a width of seventeen inches, the pitcher is able to see the width of the plate better and the umpire can judge balls and strikes with less difficulty. \n\nThat was a good question so i looked it up

Another reason for astroturf is to give the ball a true bounce, so there aren't as many tricky hops for the fielders.  The dirt is near the bases for sliding purposes.  The dirt on natural surfaces, if you think about it...there is a lot of traffic on the base paths so the grass is easily worn out and eventually would turn to dirt...so I believe fields gradually were made with just dirt around the base paths as years progressed way back when

The foul pole appears to have evolved from the foul lines themselves. According to photos from the Baseball Hall of Fame, foul lines in pre-1900 ballparks extended only halfway down the line from first and third base to the outfield fence or wall. Eventually the foul lines reached the outfield wall. Subsequently, a white stripe was painted vertically on the wall perpendicular to the foul line.\n\nAround the turn of the century, short, white, wooden foul poles approximately 10-15 feet high were erected. Hall of Fame umpire Jocko Conlan recalled, "In some parks, the foul poles were placed on the playing field in front of the outf1eld fence. If a ball hit the pole above the line of the outfield fence, it was a home run. If the ball struck the pole below the line of the fence, the ball was in play."\n\nMany years ago there was a disparity between the two leagues regarding balls that hit the foul pole above the fence then landed foul. The American League ruled such hits ground-rule doubles, whereas the National League declared such batted balls home runs which is currently the interpretation for both leagues

Yes.  There is a tunnel to get to the infield.

Those are farming plots.  Many places in the southwest, have these circular irrigation systems where there is a fixed stand in the middle of the field and a long arm with sprinkers on it extends out from the stand to a wheel on the far end.  Using the wheel, the arm rotates in a slow circle around the field (like the hand on a giant clock face) watering the plants beneath it.  The result is a circular field that is quite distinct looking from the air.

first recognize that its a curve by its spin. (It should be spinning on a sort of axis around the top area of the baseball.) Then just wait on it and swing. Be careful if it starts outside because if its any good it will curve out of your reach,also watch for the inside curve because it will break in for a strike. (This is for a righty pitching to a righty)

WHIP is  walks + hits divided by innings pitched.   where have you seen the FWTW?  Have NO idea what that is.

Do you mean the wrench?  There was some wrench logo on the side of the field.  I don't know what it really was or what it means.
