Normally, a pitcher labors through the final outs of any outing. The human arm just wasn't designed to throw a baseball 100 miles per hour repeatedly in a few-hours' span.
Well, Stephen Strasburg isn't your normal pitcher. In his debut, he actually got stronger the further into the game he pitched, evidenced by retiring 10 consecutive batters following Delwyn Young's 2-run HR, the last 7 of which were struck out consectuively.
But take a look at the last batter he faced, Andy LaRoche. The poor third baseman struck out on three pitches:
Pitch 1: 83 MPH curveball (called strike)
Pitch 2: 83 MPH curveball (swinging strike)
Pitch 3: 99 MPH fastball (swinging strike)
It's the last pitch that really sticks out: 99 mile per hour gas on his 94th and final pitch of the ball game? Are you kidding me?!
While the 99 mile per hour heat is surely a joy to watch, it's that first pitch that was so unhittable it was silly.

How do those knees feel, Mr. LaRoche?
