Obstruction?

Remember that you have to have two things for obstruction - a fielder in a position that causes a runner to react (assuming no imminent play) AND a runner that actually does react (whether by his own will or by contact).

Negative. If the runner slid directly into the catcher, as he should, he did not alter his path, and altering is not necessary to get an obstruction call. It if was block, pause, catch, tag then obstruction is the correct call.
