In the top of the fifth inning, Shaun Marcum drilled one of Josh Collmenter's batting-practice fastballs deep into the power alley in left-center field.

This was a surprise.

The drive was caught by Gerardo Parra, and could also have been caught by Chris Young.

This was not a surprise.

When it comes to outfield defense, nobody's got what the Diamondbacks have got.

Just the other day, I filled out my Fielding Bible ballot.

Gerardo Parra was my No. 1 left fielder in the National League.

Chris Young was my No. 1 center fielder in the National League.

Justin Upton was, if memory serves, my No. 1 right fielder in the National League.

One can't really credit this brilliant outfield defense with much of the Diamondbacks' turnaround this season, because all three of those guys were the regulars a year ago.

It sure doesn't hurt, though. And while a Diamondbacks win tonight doesn't exactly turn this series around, it will mean we get at least one more game with baseball's greatest outfield.
