The average fastball is between 50-60 mph. Although at this age the players may begin to reach puberty, and for that reason, it is not unusual to see a pitcher throwing around 70 mph. The changeup velocity at this age is generally between 40-50 mph.
This is answered for every age imaginable, if you search the forums for details. Short answer is is 55-60 mph. Anything faster than that is above average.

Division III players have a pitching velocity of 77 miles per hour to 82 miles per hour on average. Along with this, coaches often look for Division III players to have a strikeout to walk ratio of 1:1 and an ERA ranging from 2.50 to 3.50.
Does a curveball hurt your arm?
No studies found increased force or torque about the elbow or shoulder. Three epidemiologic studies showed no significant association between pitching a curveball and upper extremity pain or injury.
Does throwing a sinker hurt your arm? No. The sinker has a similar arm slot and grip as the two-seam fastball. The sinker generally safe.

Average freshman pitcher (14 to 15 year old) cruising speed would be about 70 mph. Average cruising speed for a good high school pitching prospect at 14 to 15 years old would be about 75 mph.
My nephew is 15, throws in the low 70- mid 70's and will make the V-team as a pitcher in a 5A school. He does have good stuff and control, just not overpowering. General rule of thumb for good-to-great velocity is AGE x 5 MPH. So, at 10, 50; at 12, 60; at 15, 75, at 17, 85.
Four-Seam Fastball
This is usually the easiest pitch to throw for a strike. If released properly, four laces of the ball rotate through the air, helping to keep the throw in line with the target. Pitchers should hold the baseball with their pointer and middle finger on the top laces or seams of the baseball.
The curveball should be thrown – just like all pitches – as hard as the fastball. The arm-speed for all pitches should be 100% at all times, but the output speed, the final radar gun speed, is determined by how much speed is converted into spin.
Throwing a curveball prior to age 13 was not found to be a significant risk factor for the development of a serious arm injury, defined as one requiring shoulder/elbow surgery or leading to retirement from baseball.
Little League did not institute a ban on curve balls, and, in light of new research suggesting that the pitch does not, contrary to conventional wisdom, put more strain on a young pitcher's elbow than other pitches (indeed, the research suggests curveballs place less stress on the elbow than a fastball), was perhaps ...

A hitter is more likely to contact a fastball, but curveballs have more power potential. Basically, a hitter is more likely to get on base by hitting a fastball, but a curveball has more capacity for extra bases. Hunting one pitch over the other may be situational.
And the consensus of the pros is that the curveball is the toughest pitch to hit.
Movement. The 12 to 6 curveball is the toughest type of curveball to hit, because it moves vertically, and has no horizontal break. The difference of the speed from a fastball and the break make the pitch difficult to hit if a pitcher uses it correctly in a pitching sequence.
Each baseball player has their own specialties. However, the two pitches that stand out to be the hardest to hit are the splitter and the slider. This conclusion is backed by research that has been done to detect the whiff rate for various pitches.
The right age to start throwing a slider or curveball is between 14 and 15, which gives a player enough time to develop the pitch (takes 1-3 years) so that it's good by the time the college recruiting process heats up.

Generally, pitchers see their velocity peak in their early 20s and steadily decline by a full mile per hour by age 26. After that, velocity drops more sharply and continues a steep decline into a pitcher's 30s.
