How Can I Add Velocity From The Outfield

Is a human able to throw a baseball straight up at a greater velocity than it will attain on the way down?

Unless there's something pushing it on the way down, the speed on it's way down will never exceed the speed that it was thrown at.Discounting frictional forces and setting the initial height of the ball at a point with 0 potential energy, when you throw the ball up, at the beginning it has some kinetic energy E, and as it rises, the kinetic energy goes to 0 as its potential energy increases to E. At the very top, kinetic is 0 and potential is E. When it starts falling, potential energy decreases, back to 0 at the starting point, while kinetic energy increases back to E.Now if you add in air resistance, the total mechanical energy, which is P+K, constantly decreases, so even if all of the mechanical energy is kinetic energy at the very end, there's less of it so the ball will never reach the speed that it was thrown at.So yes, in most cases, the speed of the ball when it's thrown will be the maximum speed of the ball. The only exceptions I can think of are if maybe the wind starts blowing or some other force acts downwards right as the ball starts moving downwards, but that doesn't seem very likely.

Why do they wear gloves in baseball?

Here is a start to this answer. (I won’t pretend to fully understand the ins and outs of cricket strategy.) Gloves are used in baseball mostly because of the distinct requirements of the games and strategies of the batter.First, except for the catcher, baseball gloves are used to extend the reach of the fielder, and to facilitate subsequent play, which must be quick and timely.Second, in both games the speed of the ball toward the batter (pitching vs. bowling) is similar, and the balls are similar. But in cricket the object of the batter is to protect the wickets and direct the ball to the field safely. The batter does not need to run, and his turn at bat can last for hours. As such, hitting the ball with force is not required; there are many options for hitting and remaining at bat.In baseball, however, once the batter puts the ball into play his turn at bat is completed. He either reaches base safely, or he is out. Each at bat must somehow add value, or it becomes one of the 27 maximum outs in a 9-inning game. Further, the tubular shape of the bat does not allow for as precise placement of the pitched ball. A bunt is the safest type of hit, and a skilled fielding team usually achieves an out.As such, the primary intent of the batter differs between the games, with cricket allowing batsmen to hit safely with no penalty. If I understand correctly, batsmen primarily seek to avoid a dismissal, and secondarily to add to the team’s runs. But in baseball, hitting with force is necessary, as the primary intent of baseball batters is to get on base, or to move a runner forward (i.e., a ‘sacrifice’ toward scoring a run).Finally, in cricket only the catcher wears a protective glove and leg pads. Baseball players would like to know:WHY DO CRICKET BATSMEN WEAR SO MUCH PROTECTIVE GEAR? - more than our baseball catchers, it seems! Our batters are only required to wear a removable helmet.

Does every pitcher that throws 90mph and more get drafted to the MLB?

I'd qualify this question by adding one key phrase: "Does every high school pitcher that throws 90mph get drafted?"  And I'm inclined to say, Yes (if they're willing to get drafted, that is; see later).  If you're 17 to 18 and are already hitting 90, odds are that you're still continuing to grow, still able to put on many pounds of muscle and likely can add more MPH to that 90 mph existing fastball.  Therefore teams are more than willing to sign you, pay you the minimum wages for 6-7 minor league seasons while you grow up and see if you pan out.I add the caveat "if you're willing to get drafted" because as we've seen, many prep prospects make it known early in the process that they intend to go to school, and the new draft rules make it quite difficult to "buy out" players of these hard-line committments.  And, many more get deeper into the draft where they just can't get the life changing bonus offers and end up going to school.Once a guy has 3-4 years of college in him, as noted elsewhere 90mph isn't enough.  You need to throw 90 and have 3 projectable pitches, or have excellent command, or have great natural movement, etc.  Of course, it is worth saying that somewhere in the 20-25% range of division 1 players get drafted anyway ... there's lots of spots to fill in the short-season and rookie league teams.  So you have a good chance if you can at least break the 90mph barrier, but you'll face long odds to move up.

If I am a 17-year-old, 165 lb pitcher, and can consistently throw 79-82 MPH for my fastball, if I get up to 200 lb with 12% or less body fat, should I be able to throw in mid 90s or at least the 90s?

Bodyweight has been directly correlated to fastball velocity.Relationships between ball velocity and throwing mechanics in colle...I touch upon this point here: "As a general rule of thumb, our Sacred  Heart pitchers will gain 2-4 mph a  season during their 4 years in  college.  As much as I would love to say  it’s just training, there are  numerous reasons why we get increased  ball velocity each year including  mechanical improvement, growth of body  due to puberty, increased  muscle mass, and improved body  awareness/muscular coordination.   The  interesting trend is that most of  our athletes tend to add anywhere  from 5-15 lbs of bodyweight each  year. Does 5-15lbs = 2-4mph on the  mound?  Maybe."Why All Baseball Players Should Be Using CreatineWith my pitchers, we have the following hierarchy/system:1) Mechanics Rule All: Increase mechanical efficiency your energy leaks will decrease and velocity will go up.2)  Increase General Strength: Building a foundational base strength is not  only performance enhancing, but done properly will decrease the risk of  injury.3) Increase Muscle Mass: More muscle mass, the more potential to apply force.4)  Increase General Force Production (e.g. Power): Allows us to tap into  more high threshold motor-units to produce more force and increase IIx  muscle fiber.5) Increase Skill Specific Power: Explosive training in  a transverse plane. This could be med ball throws, weighted or  under-weighted ball throws, long toss, flat ground or even mound work.We  have had many mid 90MPH pitchers (injury free to boot) as well as some  whom have touched 99+MPH. Some of these athletes have gained upwards of  50lbs of very clean weight (still viable abs) in less than a year.  Everyone is different based on genetics, work ethic, movement  capabilities, diet etc.Alan Jaeger is outstanding. He get's the whole spectrum of training and popularized formal long toss.If  you are mechanically efficient, have relatively long levers and can  increase body mass to 200lbs and force production increase  proportionally it is very possible.
