Baseball trivia (not Barry Bonds)

Someone told me this about this player when we were discussing him at lunch today, and lo and behold it's true, not an urban legend.

Without using Google or any other search engine, tell me, "Who is the only player in MLB history to homer in his only World Series at-bat?"

 

Bill Bathe?

 

No. He had three WS at-bats. He did have a homer in the 1989 WS after not hitting one in the regular season, tho.

 

some Yankee scrub in '77 I think but I can't remember who

 

Jim Mason, 76 Junkies....

 

Jim Mason is correct.
