“I was one for two”

Question

The following dialogue snippet comes from True Blood. A man comes onto a woman with a pickup line, and she replies: "Okay, that was a good line." "Well, I only used it on two other women before you." "Really? And how'd it go with them?" "I was one for two."

That last line is what puzzles me. Is it a real expression, or have I misheard the line?

Answer 1

"One for two" means someone had one success for two tries. It comes from sports, originally baseball, in which a player would be said to be "one for two" if he had two at-bats but only got one hit.
