Runner Hit by Batted Ball after Deflection

 
With two outs and runners on second (R2) and first base (R1), the batter (B1) hits a hard line-drive up the middle. The line-drive ricochets off the pitcher's glove and then directly towards the shortstop. However, before the shortstop can field the ricochet, the ball hits R2 (unintentionally) as he runs toward third base. All runners are safe at their next base. 
 
What actions should the umpire take?
 
Call
After a batted ball has touched an infielder, it is not interference if the runner is then unintentionally struck by the ricochet (NF 8-4-2k). In the situation below, since the batted ball first touched a fielder and R2's actions were not intentional, there is no penalty and the ball remains live and in play.
