Coincidentally, Rodriguez's injured elbow was the impetus for Houston to call up the 20-year-old Lyles, who is now the youngest player in the Majors at 20 years, 224 days. He's also the youngest to make his big league debut for the Astros since Cesar Cedeno did it at 19 years, 115 days.
"I'm sure he's just going to go out there and pitch," Norris said before Tuesday's game. "He's going to be around for a while. He's a young guy and he's got a lot of good stuff. I just hope he cherishes the moment before he steps on that mound and knows he's worked so hard to get here."
Norris did exactly that for the Astros on July 29, 2009, when he threw three innings of relief and allowed just one run in his own Wrigley Field debut.
"Three innings and one run ... I was pretty excited for my debut, and I've never been back to the bullpen since," Norris said. "It was a flash. It just went really quick. I don't really remember much except getting done with it and looking at the linescore. But I had Mom and Dad in the stands and that was really special that they could be here. There's no better place to debut than Wrigley Field."
