Can it be that it would have been even though it might not have been?

The score was tied in the bottom of the ninth, I was on third base, and there was only one out when Bubba hit a towering fly ball to deep left-center. Although I’m no speed-demon, the ball was hammered so far that I easily could have scored the winning run if I had tagged up. But I didn’t. I got caught up in the excitement and stupidly played it half way, standing between third and home until I saw the center fielder make his spectacular catch, after which I had to return sheepishly to third. The next batter grounded out, and we lost the game in extra innings
