"We were walking into class and people started saying something," Chamberlain said. "Obviously no one really knew what was going on. We all went down to the auditorium, and they had TVs set up, and we saw the second plane hit the World Trade Center."
Chamberlain had no way to know that he'd one day wear "New York" across his chest; in fact, he'd never even been on an airplane. But the future Yankees reliever, like most everybody else, vividly remembers the emotional flood that accompanied the worst terrorist attack in United States history.
"We were all making phone calls and trying to figure out what was going on the rest of that day," Chamberlain said. "There were so many rumors, like that gas was going to go up to $9 a gallon. My dad was out there directing traffic for the gas station. You obviously didn't know what was going on."
More than 500 miles east, manager Joe Girardi was living in Chicago at the time, then a member of the Cubs. He said that he was in his family room that morning with his wife Kim and their daughter Serena.
"A friend in New York called us and said, 'You've got to turn on the TV. You're not going to believe what's happening,'" Girardi said. "And I was in shock. I was scared. I was sad.
"It was a terrible day. I had the TV on all day. At 7 o' clock, I finally said, 'You know what? I've got to take a walk outside to get some fresh air and think about what's going on.' You could hear fighter jets flying over near O'Hare Airport. It was a scary, scary day."
In New York, Derek Jeter checked his messages that morning and found a voice mail from teammate Jorge Posada, asking if the Yankees' game that night would be cancelled. Jeter flicked on his television and saw that the Manhattan skyline had been forever altered.
Once baseball resumed, Jeter recalled an "uncomfortable" feeling. Many in the wounded city looked to him and his teammates for diversion and inspiration; as workers at Ground Zero huddled around radios to listen to game broadcasts, the Yankees charged through the postseason and battled the D-backs in an epic seven-game World Series.
"We'd been a part of a lot of big games over the years, but that was probably the loudest I heard Yankee Stadium," Jeter said. "We gave New Yorkers something to cheer for."
