What's the award?

2 bases TOD (time of departure) from the field.
Unless it's a "legal catch", consider the carry OOP a throw.

OBR 7.05
Each runner including the batter-runner may, without liability to be put out, advance—

(g) Two bases when, with no spectators on the playing field, a thrown ball goes into the stands, or into a bench (whether or not the ball rebounds into the field), or over or under or through a field fence, or on a slanting part of the screen above the backstop, or remains in the meshes of a wire screen protecting spectators. The ball is dead. When such wild throw is the first play by an infielder, the umpire, in awarding such bases, shall be governed by the position of the runners at the time the ball was pitched; in all other cases the umpire shall be governed by the position of the runners at the time the wild throw was made;

7.04(c): Each runner, other than the batter, may without liability to be put out, advance one base when a fielder, after catching a fly ball, falls into a bench or stand, or falls across ropes into a crowd when spectators are on the field;

Rule 7.04(c) Comment: If a fielder, after having made a legal catch, should fall into a stand or among spectators or into the dugout or any other out-of-play area while in possession of the ball after making a legal catch, or fall while in the dugout after making a legal catch, the ball is dead and each runner shall advance one base, without liability to be put out, from his last legally touched base at the time the fielder fell into, or in, such out-of-play area.

Oops, didn't read carefully enough to see that there was no catch.
