I don't know if you were following the Nationals/Brewers game closely, but this was the first game Nationals pitching prospect Bill Bray ever pitched in. He entered in the bottom of the 8th with the Nats down 3-2, threw ONE pitch for a strike, and then Brian Schneider gunned down a runner attempting to steal second for the last out of the inning.

The Nats took the lead in the top of the ninth, of course, putting Bray in line for the win.

The question, therefore, is this: is Bray the first pitcher to win a game on his first and only Major League Pitch? That's got to be some kind of (trivia) achievement, right?

I believe there's been some research on the issue, so I'll see what I can find.
