"Are you nervous?" one girl asked another, lined up along the left-field line before the event got underway.
"Yeah," she replied. "I didn't think I would be, but now I am. It's so cool."
The boys and girls were divided into four age groups: 7-8, 9-10, 11-12, and 13-14. They had already advanced past local and sectional rounds, and this was the final hurdle.
All 30 Major League clubs hold a Pitch, Hit and Run competition, and the top three scorers nationally in each age group compete in the finals during All-Star weekend.
"Way to go, Superman!" yelled one supporter to Andrew Saldana of Lathrop, Calif., after he fired a few strikes in the pitching portion.
The kids got three swings apiece off a tee from home plate, and were timed dashing from second to home.
Final scores were calculated, winners were announced, and everyone, regardless of performance, received a plaque.
"You were on a Major League field," one dad reminded his son after meeting him in the stands behind third base.
For some of the kids, that simple fact was enough.
"Dad, look what I got: a ball that was on the field!" beamed Connor Poreidor of Jackson, Calif., the winner of the ages 7-8 boys division.
Then he added, almost as an aside: "I hope I get to go to..."
"Minnesota," he was reminded.
The national finalists will be announced June 29 on MLB Network.
