It has been explained as an optical illusion. Research has shown that doubling the weight of a 20-ounce wood bat can raise a BBS of 68.5 mph to 80.4 mph -- a 17.3 percent increase. The added back-spin from the higher speed further decreases the amount of sink. Hence, to the hitter, an overhand pitch will appear to be thrown at a hitter's shoulder level (or even belt level), as opposed to several inches above the hitter's head, from where the pitch is actually released from the pitcher's hand. A curveball can carry topspin of 1900 rpm, making it bite downward as it crosses the plate. The batter perceives it as a fastball which has risen and increased in speed.

It can take nearly 25 milliseconds for the brain's signals to pulse through the hitter's body and start his legs moving. Some batters are under the impression that they have seen a "rising" fastball, which starts with the trajectory of a normal fastball, but which as it approaches the plate rises several inches and gains a burst of speed. A more distant pitcher's mound and other changes have been proposed to restore balance.[6]. Zimmerman has discovered the same principle with his 34-in., 32ounce MaxBat. Assume that the collision occurs three-fourths of the way from the pitcher's mound to home plate. Other researchers may be more fascinated by the science behind the game. But Daniel Russell, a professor at Kettering University in Michigan, found that doubling the swing speed of a 30-ounce bat can raise a BBS of 62 mph to 83.8 mph -- a 35.1 percent increase.

The pitch velocity gone up so much mostly by the development of better training and clearer communication within the baseball community that velocity is so valued. Speed helps, but understanding the route to run, the arm strength of opposing outfielders and the game situation are more important skills than flat-out speed.
Go to www.killsometime.com and watch the "Bird Baseball" clip. A two-seam fastball, sometimes called a two-seamer, tailing fastball, running fastball, or sinker is another variant of the straight fastball. Two general methods are used to throw a four-seam fastball. To hit the ball out of the park, a batter must reverse the rotation of the ball so that it leaves the bat with backspin. Left-hander Sid Fernandez was known for throwing a rising fastball from a slightly "submarine" motion. [2] The four-seam fastball is the most common variant of the fastball.

Willie Feng -- 2005. "Power pitchers," such as former American major leaguers Nolan Ryan and Roger Clemens, rely on speed to prevent the ball from being hit, and have thrown fastballs at speeds of 95–105 miles per hour (153–169 km/h) (officially) and up to 108.1 miles per hour (174.0 km/h) (unofficially). [4][5], Higher pitch velocities have resulted in fewer hits and other imbalances. The fastball is the most common type of pitch thrown by pitchers in baseball and softball. Depending on the grip and pressure applied with the fingers, sometimes the two-seam fastball features more sink than lateral movement. A side-arm fast ball is thrown from an angle different from the normal one. The batter has another 50 milliseconds to decide whether to swing, and where, before he must act. A splitter usually drops as it approaches the plate, and breaks to either the right or left. As a curveball was often called an "outcurve", one might assume that an incurve is the opposite of a curveball, in other words, the modern screwball. But swing speed can affect BBS more dramatically. The thumb then rests underneath the ball about in the middle of the two fingers. Randy Johnson, the pitcher on the mound, throws a pitch which fatally hits a dove that flies by from the right of the screen. Convert the velocity from m/s to mph.

In 2008 the average fastball thrown in the MLB was 90.9 mph. Because the fingers are spread wider than normal on the baseball, this pitch produces more stress from the hand up through the arm.

If the ball was hit when it was 1.0 m above the ground, what horizontal distance does it travel before it lands on the building? The pitch is used often by the pitcher to get ahead in the count or when he needs to throw a strike.

But Rod Cross, a physicist at Australia's University of Sydney, found that the spot is more like a zone. Hits between the two produce minimal vibration -- and transfer more energy -- at both frequencies. People like Tom House, Eric Cressey, Kyle Boddy, and Ron Wolforth have all pushed the edge and dedicated careers to research on what makes the ultimate pitcher. Baseball's "king of swat" Babe Ruth reportedly began his hitting career using a 54 ounce (1.5 kg) hickory bat, and is known to have used a 40oz bat in 1927 when he hit his 60 home runs. The four seam fastball is widely regarded as the main key to advancing to the next level of play. But Daniel Russell, a professor at Kettering University in Michigan, found that doubling the swing speed of a 30-ounce bat can raise a BBS of 62 mph to 83.8 mph -- a 35.1 percent increase. A batter takes 100 milliseconds to see the 3-in. This usually causes the pitch to shift inwards or outwards by a few inches, less than a typical slider, and often late. A straight pitch is achieved by gripping the ball with the fingers across the wide part of the seam (called a "four-seam fastball") so that both the index and middle fingers are touching two seams perpendicularly. The answer to that question is "both," though past players tend to have used heavier bats than do today's players. The thumb needs to rest on that seam from the side to the middle of its pad. Afterwards we can analyze and see why he chose that … (II) A baseball is hit with a speed of 27.0 m/s at an angle of 45.0$^\circ$.

What is likely happening is that the pitcher first throws a fastball at one speed, and then, using an identical arm motion, throws another fastball at a higher speed. Having speed alone does not make one a good base runner. A cutter is effective for pitchers with a strong four-seamer since the grip and delivery look virtually identical. The first and most traditional way is to find the horseshoe seam area, or the area where the seams are the farthest apart. This ball tends to move for the pitcher a little bit depending on velocity, arm slot angle, and pressure points of the fingers. Tom Seaver, Jim Palmer, Sandy Koufax, Dwight Gooden, Nolan Ryan and Chan Ho Park have been described as paramount pitchers with this kind of ball action. Find the average velocity of the baseball using the formula v = ∆x/∆t. However, this does not appear to be so, as cited by John McGraw. A good base runner will listen to advice from coaches on the base paths, but will make the final decisions whether to run or stop based on his own knowledge. To show the effect that this increase in velocity has had on hitters in the big leagues, we can look at the runs scored stat. This perception enhances the apparent "rising" motion of the fastball when the pitch passes the hitter at a higher level than where the hitter perceived the pitch to have left the pitcher's hand. Retired pitchers Greg Maddux and Pedro Martínez were known for their effective two-seamers. v = ∆x/∆t v = 13.8 meters/0.3 seconds v = 46.0 m/s. "I'm thinking about what the pitcher might throw in that situation," says the 22-year-old rising star with the Washington Nationals.

In his prime, Rivera could deliver late motion while throwing the ball around 96 mph. When the pitch is thrown, the batter expects a fastball at the same speed, yet it arrives more quickly and at a higher level. Find the average velocity of the baseball using the formula v = ∆x/∆t. Factoring in the element of depth perception when the hitter watches the pitcher from 60 ft 6 in away from the pitcher's mound, and the hitter perceives the pitcher's size and positioning on the mound to be less elevated than it actually is.
