They say baseball is a game of inches.

Well, they're wrong. It's actually less than that.

The video below shows how close Oakland A's outfielder Chris Young came to hitting a walk-off, two-run home run on Tuesday night, against the Houston Astros.

The Astros led, 5-1, going into the bottom half of the eighth inning, before the A's put up three runs, cutting the lead to 5-4.

Young came up in the bottom of the ninth facing Astros reliever Chia-Jen Lo with two outs and a runner on first base.

The Houston native belted a pitch down the left-field line, and as you can see, came as close as you can get to hitting a run without doing so.

It's looks like the umpires got it right. The ball looks foul on replay. But remember, all the ball has to do it graze the foul pole, so even with replay, it's hard to be 100% sure.

Judging from the replay however, it looks like a great call by third base umpire Doug Eddings.

The Astros held on to win, 5-4.
