2. The batter-runner may turn left or right, provided that if he turns left he does not make an attempt to advance. An attempt is a judgment made by the umpire. The requirement is that the runner must immediately return to first after overrunning or oversliding it.
Rule: 7.08(c and j) Official Baseball Rules
3. A strike is a judgment by the umpire as to whether the batter attempted to strike the ball. Breaking the wrists, or the barrel of the bat crossing the plate are simply guides to making the judgment of an attempt, these are not rules.
Rule: 2.00 STRIKE Official Baseball Rules
4. The plate is in fair territory. There is nothing special about it. If a batted ball hits it, it is treated like any other batted ball.
5. The batter's box is not a safety zone. A batter could be called out for interference if the umpire judges that interference could or should have been avoided.
Rules: 2.00 INTERFERENCE, 6.06(c) Official Baseball Rules.
6. There is nothing foul about a foul-tip. If the ball nicks the bat and goes sharp and direct to the catcher's hand or glove and is caught, this is a foul-tip by definition. A foul-tip is a strike and the ball is alive. It is the same as a swing-and-miss. If the ball is not caught, it is a foul ball. If the nicked pitch first hits the catcher somewhere other than the hand or glove, it is not a foul-tip, it is a foul ball.
Rules: 2.00 FOUL-TIP, STRIKE Official Baseball Rules
7. The batter can switch boxes at any time, provided he does not do it after the pitcher is ready to pitch.
Rule: 6.06(b) Official Baseball Rules

Rule: 6.07(b, 1) Official Baseball Rules
9. Rule 7.08(c and j) simply state that a batter-runner must immediately return after overrunning first base. It doesn't state any exceptions as to how the player became a runner. It could be a hit, walk, error or dropped third strike. See Official Baseball Rules
10. The batter may attempt first base anytime prior to leaving the dirt circle around home plate.
Rule: 6.05(c), 6.09(b) Casebook interpretation Official Baseball Rules.
11. A strike is an attempt to hit the ball. Simply holding the bat over the plate is not an attempt. This is umpire judgment.
Rule 2.00 STRIKE Official Baseball Rules

Rules: 6.05(h) and 7.09(b) Official Baseball Rules
13. To be out the batter's foot must be ENTIRELY outside the box when he contacts the pitch. There is no statement about touching the plate. The toe could be on the plate and the heel could be touching the line of the box, which means the foot is not entirely outside the box.
Rule: 6.06(a) Official Baseball Rules
14. The runner must be out of the box AND cause interference. He is not out simply for being outside the lane. He could be called for interference even while in the lane. This is a judgment call.
Rules: 2.00 INTERFERENCE, 6.05(k), 7.09(k) Official Baseball Rules
15. The ball is dead on a homerun over the fence. You can't be put out while the ball is dead except when you pass another runner.
Rules: 5.02, 7.05(a) Official Baseball Rules
16. There is no such thing in the world of umpiring. The runner is either out or safe.
17. When a fielder other than the pitcher throws the ball into dead ball area, the award is 2 bases. The award is from where the runners were at the time of the pitch if it is the first play by an infielder before all runners have advanced or from where each runner was physically positioned at the time the ball left the throwers hand on all other plays.
Rule: 7.05(g) Official Baseball Rules
18. Rule 7.09(I) says the runner is out if the coach PHYSICALLY ASSISTS the runner. Hand slaps, back pats or simple touches are not physical assists.
19. In order to correct a base running mistake, the runner MUST retrace his steps and retouch the bases in reverse order. The only time a runner is out for running in reverse, is when he is making a travesty of the game or tries to confuse the defense.
Rules: 7.08(I), 7.10(b) Official Baseball Rules
20. There is no "must slide" rule. When the fielder has the ball in possession, the runner has two choices; slide OR attempt to get around the fielder. He may NOT deliberately or maliciously contact the fielder, but he is NOT required to slide.
Rule: 7.08(a, 3) this rule does not apply to professionals.
See Sliding and Collisions.
21. The bases are in fair territory. A runner is out when hit by a fair batted ball, except an infield-fly.
Rules: 5.09(f), 7.08(f) Official Baseball Rules
22. There is nothing foul about a foul-tip. If the ball nicks the bat and goes to the catcher's glove and is caught, this is a foul-tip by definition. A foul-tip is a strike and the ball is alive. It is the same as a swing-and-miss. If the ball is not caught, it is a foul ball.
Rules: 2.00 FOUL-TIP, STRIKE Official Baseball Rules
23. A force play is when a runner is forced to advance because the batter became a runner. When the batter is out on a caught fly, all forces are removed. An out on an a failure to tag-up, is NOT a force out. Any runs that cross the plate before this out will count.
Rules: 2.00 FORCE PLAY, 4.09 Official Baseball Rules
24. A runner must touch all the bases. If the runner misses a base to which he was forced because the batter became a runner and is put out before touching that base, the out is still a force play. If this is the third out, no runs may score. The base can be touched or the runner can be touched, either way it's a force out.
Rules: 2.00 FORCE PLAY, TAG, 7.08(e), 7.10(b) Official Baseball Rules
25. The runner MUST avoid a fielder attempting to field a BATTED ball. A runner is out for running out of the baseline, only when attempting to avoid a tag.
Rules: 7.08(a), 7.09(L) Official Baseball Rules
26. An Infield-fly is no different than any other fly ball in regard to the runners. The only difference is that they are never forced to advance because the batter is out whether the ball is caught or not.
Rules: 2.00 INFIELD-FLY, 6.05(e), 7.10(a) Official Baseball Rules
27. Yes it can. This is not a force play. A force play is when a runner is forced to advance because the batter became a runner. When the batter is out on a caught fly, all forces are removed. An out on an a failure to tag-up, is NOT a force out. Any runs that cross the plate before this out will count.
Rules: 2.00 FORCE PLAY, 4.09, 7.10(a) Official Baseball Rules
28. A pitch is a ball delivered to the batter by the pitcher. It doesn't matter how it gets to the batter. The batter may hit any pitch that is thrown.

31. You can tag a base with ANY part of the body.
Rules: 2.00 FORCE PLAY, PERSON, TAG, 7.08(e) Official Baseball Rules
32. In Federation rules it is, not in any others. If a throw or pitch is made after the balk call, the ball is delayed dead. At the end of the play the balk may be enforced or not depending on what happened. On a throw; if ALL runners advance on the play, the balk is ignored. If not, the balk award is enforced from the time of pitch. On a pitch; if ALL runners INCLUDING the batter, advance on the play, the balk is ignored. Otherwise, it is no-pitch and the balk award is made from the time of the pitch.
Rule: 8.05 PENALTY Official Baseball Rules
33. The position of the player's feet or any other part of the body is irrelevant. A ball is judged fair or foul based on the relationship between the ball and the ground at the time the ball is touched.
Rule: 2.00 FAIR, FOUL Official Baseball Rules
34. An appeal may be made anytime the ball is alive. The only time the ball must go to the pitcher, is when time is out. The ball cannot be made live until the pitcher has the ball while on the rubber and the umpire says "Play." If time is not out, the appeal can be made immediately.
Rule: 2.00 APPEAL, 5.11, 7.10 Official Baseball Rules
35. A pitch is a ball delivered to the batter by the pitcher. If the ball is not delivered, it is not a pitch. If this happens with runners on base it is a balk.

36. The pitcher is required to come to a complete stop in the Set position before delivering the pitch, not before making a throw.
Rule: 8.05(m) Official Baseball Rules

Official Baseball Rules
38. As long as the fielder is not touching the ground in dead ball territory when he catches the ball, it is a legal catch if he holds onto the ball and meets the definition of a catch. If the catch is not the third out and the fielder falls down in dead ball territory, all runners are awarded one base. If the fielder remains on his feet in dead ball territory after the catch, the ball is alive and he may make a play.
Rules: 2.00 CATCH, 6.05(a), 7.04(c) Official Baseball Rules
39. If an umpire is hit by a batted ball before it passes a fielder, the ball is dead. On any other batted or thrown ball, the ball is alive when the umpire is hit with the ball. Umpire interference also occurs when the plate umpire interferes with the catcher's attempt to prevent a stolen base.
