Watch Tennessee Pitcher Throw 103.5 Miles Per Hour

Initially I thought the same, but watching them wave at it....he's bringing it and seems to be effortless.

then he had a stroke on the field at practice or warming up.

yep … Damn, I see that too

Did he do this last year or was he just holding back.

105 is not the absolute limit but the faster you throw the more dangerous it is to the batter. That is two separate but distinct facts.

The article he is talking about was in Popular Mechanics and said 105 is "testing the limits" of torque the elbow can take/create. But like he says, the radar guns may be a bit off. The UCL can only withstand so much. Everybody's is made of the same stuff and the article states that throwing at 105 is on par with having a 60lb weight hanging off of your hand at that awkward cocked position. There is most definitely a limit to how fast you can throw a ball unless you start finding ways to increase the amount of torque a UCL can take.
