Was Soriano nervous playing in the event?
"A little bit," the Cubs veteran said. "I was a little nervous because we were playing on a big league field. I said, 'One day, I'm going to play in those ballparks.'"
Castillo took part in the 2008 game, the last All-Star event held at old Yankee Stadium. His World teammates included Pablo Sandoval, Ivan DeJesus Jr. and Hector Rondon, then with the Indians and now on the Cubs staff.
Castillo said he couldn't tell who among his teammates would make the big leagues.
"Honestly, I wasn't sure I'd make it," Castillo said. "I wasn't a good catcher at that point because I was an infielder, and still learning a lot about catching. It was a good experience to be around those guys. I saw that a couple of the guys got a Major League debut in September, and I said, 'OK, I need to keep working hard because I want to make it.'
"Being in that game, it opened your eyes," he said. "I think it gave me a lot of confidence."
Edwin Jackson was on the U.S. Team for the 2003 Futures Game played at U.S. Cellular Field.
"All the names you see now, pretty much most of the people in the Futures Game find their way to the big leagues somehow," Jackson said.
Did he think he would make it?
"At the time you're just enjoying it," Jackson said. "You're talking about guys coming from Double-A, Single-A. Back then, you're 26, and you're still considered young. It's not like it is now."
