Alex helped me practice pitching just before
Jon Hartman had given Ron pitching pointers earlier in the week, and Gail had helped practice too!
Thanks, Alex, Gail, and Jon!
Let's see... h(t) = h0 + v0 t - 1/2 g t^2 ...

So, g is 32 ft / s^2, but what is t?
Hmmm.. 60.5 ft to home plate... I probably pitch at
20 mph = 29.3 ft / sec...
It was cold! No wonder Pedro blows on his
The moisture definitely makes the ball less slippery...
Initial dh/dt = 32 ft/sec, angle is arctan(32/29) = 47 degrees...
Hmmm... that sounds like a fly ball... I think I better forget the math and throw this thing!
Jon said point the left foot towards home plate...
I hope that cute ball girl is a good catcher!
Strike (close enough!).
The Red Sox folks let me keep the ball (which had been engraved...)
Thanks to Gail, Alex, Chris, Joe, Prabhakar, Becca, Ann, Arvind, Nisha, Jon, Jim, Beck for being there with your support!
That was both an honor, and very exciting!
Go Red Sox!
The Sox won, 6-2!
