obs

[RKBUmp]

The defensive player just being there is not necessarily obstruction, you also have to have a physical impedement of the runner. In the initial set of photos you posted there is nothing to indicate the runner slowed or altered their path to the base. In the last photo it does appear the ball is about to come out of the glove. If it did come out and the runner had not yet reached the base, then you have obstruction.
