Yes, batters can be ejected while they are batting, usually by arguing about the strike the zone with the umpire. This usually only happens after the batter has struck out, rather then in the middle of the count, but if the batter argues too much, the umpire can toss him at any time.
Pine tar from his swing and resting his bat there. I believe it has nothing to do with him resting his bat on his shoulder. A batter does not rest his bat on his FRONT shoulder. I believe, although I have nothing to confirm this, that Matt Kemp himself is putting the dirt on the uniform of his left shoulder. This is his surgically repaired shoulder and he might have developed a ritual or a superstition about it...Just a thought
The batter swinging the bat.
In the game of baseball the batter is the player who is at bat. There are many rules that the batter must follow. One of the most important rules is that the batter cannot leave his position in the batter's box once the pitcher comes to set position.
Yes the batter can switch as often as he would like. It just has to be after the strike.
That is solely up to the preference of a batter. I have noticed most batters now days use two but occasionally a batter will wear only one normally on the hand that is lowest on the bat.
That batter would be called out. If the ball goes directly from his bat to hitting the batter when they are not in the batters box, the batter is out. If a defensive player deflects the ball before it touches the batter then play continues as normal.
I used my shoulder to swing the bat in baseball.
If the wrong batter completes the at bat, then the skipped batter is recorded as an out. If it is noticed prior to the completion of the at bat the skipped batter assumes the count of the at bat and completes with no additional penalties.
Probably so the bat boy can retrieve it quickly to make way for the next batter.
If the batter is still in the batters box, it is a foul ball, otherwise, the batter will be ruled out, and it is a dead ball with runners returning to their bases This is wrong, if the ball hits the bat a second time in fair territory the batter is out, standing in the batters box means nothing in this rule. see MLB rule 6.05 h
A batter is credited with an at bat for every plate appearance except: 1) base on balls 2) hit by pitch 3) sacrifice fly 4) sacrifice bunt 5) catcher's interference If an inning ends while a batter is in the middle of an at bat (eg., a base runner is thrown out stealing for the 3rd out) no at bat is credited and the batter is the first batter to bat in the next inning. If the batter is replaced before the at bat is completed, no at bat is credited unless the batter was replaced with two strikes and the replacement batter strikes out. The strikeout is credited to the batter who was replaced.
In the 2008-2010 MLB seasons, there were 497916 total at bats and 4811 batters hit by the pitch for an average of 0.966 batters hit per 100 at bats.
