With [tag]baseball season[/tag] upon us, one of my favorite (not!) NotPhrases is back in constant use, to wit:

“There goes a line drive off of the bat of Joe Baseballer.”  Or, “He just got a hit off of pitcher Sam Flamethrower.”

I’m here to reaffirm that off of is not just redundant but incorrect.  How about, “There goes a line drive off the bat of…” and “He just got a hit off pitcher…”?

Of course, these are jocks and sports announcers using this construction, but a lot of people hear “off of” and think nothing of it and even use it themselves as a consequence.

Just stick to off, as in, “Get off my back with your lousy English.”
