 23-year-old right-hander from Venezuela. He's about to fire his first pitch of the big leagues to Jared Kelnick as Jared climbs in. Diaz looks to be ready. And now for the ball game. The first pitch swung on and missed. Showed him a fastball. Came across at 95 miles an hour. And it's nothing and one on Jared Kelnick. And Gilbert delivering from the stretch. No windup for him. And Kelnick trying to show him a little bit of what the big league's all about here.
