A young Detroit Tigers pitcher, Armando Galarraga, within one pitch of a perfect game - a feat so rare it's happened only 20 times in the 130-or-so year history of major league baseball.
He was trying for the 21st.
And he appeared to have it on a ground ball, the throw beating the runner by a step.
I saw it as it happened and I blurted, "he's out." And then the shock.
The umpire - a veteran and well-respected guy named Jim Joyce - signaled "safe."
It was the wrong call. Minutes later, Joyce approached Galarraga, told him he blew it, and hugged the young man.
Once again, the cries sounded for instant replay immediately in baseball. It now exists - but mostly for disputed home runs.
The argument against instant replay is that it compromises the traditional and "human" part of baseball, and it would make an already rather slow game (compared to other sports) even slower.
Today, Commissioner Bud Selig apparently deciding he will not reverse the call, although he didn't officially say it. Instead, he left it to unidentified sources close to him to leak that info. What Selig did say publicly is that he wanted to consult more people before making any decision - about instant replay.
So what do you think? CLICK HERE to voice your opinion. We'll have the latest, tonight - not at 11, but a wee bit later, after the basketball finals, game one.
Also tonight, an incredible story about a 22-year-old man who disappeared after a party in upstate New York early Sunday morning. This afternoon, cops found Thomas Wopat-Moreau- alive and in his car in the woods off the Taconic Parkway. He'd been marooned for all that time. Amazing.
We'll also have any breaking news of the night, plus Lee Goldberg's AccuWeather forecast, and Scott Clark with the night's sports. I hope you can join Liz Cho and me, tonight after the NBA Finals Game One.
