tjones1 and SanDiegoSteve
Started surfing the net and found this for both of you.
The article with the term "obstruction" was written by staff reporter Todd Zolecki. This may not be the article you were referring to though. Go to
http://www.philly.com/philly/sports
Scroll down to the writer Todd Zolecki's picture on the left. Click on "Guess theres no sweep. The first part that is underlined in the article "The Phillies lost last night.... should be clicked on---then go to the end of the article, "Howard scored, but wait, umpires ruled obstruction on Shane Victorino".
I do not know if this was on a back page or the front page of the Inquirer or if Todd also wrote another article on another page but changed the wording or something. Anyway tjones1 did see a Philly reporter use the word obstruction. Hope this helps.
