Question

What qualifies a baseball game to be called a comeback victory.?

Answer 1

Down by 3+ runs in the last few innings (7-9). That's how it is in my book.

Answer 2

Say the Cubs and the Cardinals are goin at it and Cards are winnin 3-0 at wrigley. Bases loaded and Soriano Homer in Bot 9. That comeback or "Walk-off homer".

Answer 3

After at least 5 innings, a team needs to be trailing and take the lead after 5 innings and keep the lead.

Answer 4

You have no runs in the 6th inning and come from behind to win. :}
