I don't recall anyone outside of a few Red Sox fans that thought the play Pedroia was hurt on was dirty.
Sometimes accidents do happen.
Am I remembering wrong? Was there an outcry from the general baseball fanbase that the play was dirty? Or was it retroconned that way after we found out how injured Pedroia was?
Here is the film.

The announcers don't seem upset, Manny appears to be honestly concerned about Pedroia (as opposed to all the catchers he's hit with his bat).
There are better ways to dirty slide.
