Ironically, Prado did not even know it was a milestone hit.
D-backs clubhouse assistant Lupe Uribe mentioned to Prado when he returned to the dugout that they were working on getting the ball back for him, and Prado was initially confused as to why.
After the game, Prado traded an autographed bat for the ball.
"I never thought I was going to get it," Prado said of hit No. 1,000. "Just to see it from when you start at one all the way to 1,000. That's a lot of hits. I can't imagine those guys that have 3,000 hits. Hall of Famers. It's a good accomplishment in my career and I'm going to keep moving on."
