Obstruction with Leaping Runner

With no outs and the bases loaded, the infield is playing in, with the shortstop even with the baseline between second and third base. The batter hits a grounder between the third baseman and shortstop. The shortstop dives for the ball, misses it, and ends up laying directly across R2's base path. R2 slows down, stutter steps, leaps over the shortstop, goes to third base and is then called out on a really close play at home plate. 
 
The defensive coach wanted R2 called out for leaping/hurdling his shortstop. The offensive coach wants R2 awarded home due to the shortstop's obstruction. What do the umpires do now?
 
Call
Leaping over a fielder is a legal attempt to avoid a fielder as long as the fielder is lying on the ground (NF 8-4-2b2).
 
Obstruction occurs when any member of the defensive team hinders a runner or changes the pattern of play (NF 2-22).
 
In the play below, the shortstop had completed his attempt to field the batted ball. He was no longer protected and he obstructed R2 attempt to advance. Since R2 was out on a close play at the plate, the umpires determined that R2 would have been safe at home had it not been for the shortstop's obstruction -- so R2's run scores.
