Strange, and unexpected. Lucky/Unlucky.

Most baseball batters are right handed (therefore swing the bat from right to left) and hit a ball out into left field.
The batter immediately drops the bat and runs to the right to get to first base.
It is quite difficult for a good left field ball to hit the ground in far left field, get picked up, and thrown, accurately across the entire field to the first baseman, before the batter can get to first base. If this does happen, its an incredible throw, from way out in left field. Totally unexpected.
This lead is right out of left field; it'll be crucial in catching the thief.

out of left field comes from when wrigley field was first built. In left field there was a insane asylum so when something crazy or unforseen happened it was termed, "out of left field"
