It's one of those baseball statistics you won't find in the morning newspaper or on a website. But all teams keep close track of pop times.

That's the amount of time it takes a catcher to receive the ball, pop out of his crouch, and throw to a base. Two seconds is considered an average time. Anything around 1.8 is excellent.

In the sixth inning on Friday, when Red Sox prospect Christian Vazquez threw out Trevor Plouffe at second base, the Red Sox had him at 1.82 seconds. It was the kind of throw that had people in the stands buzzing. In the Red Sox dugout, too.

Vazquez has the most impressive arm among a strong group of catchers in camp. It's strong and accurate, and he's not afraid to use it to throw behind runners.
