Bauer made his Major League debut on Thursday wearing No. 17, the same number he wore with Triple-A Reno this year. He was asked about the significance of the number.
"I don't know," he said. "I showed up to [Double-A] Mobile this year and I think I wore 19 last year. The clubby asked me what number I wanted. I said, 'Do you have 47?' He said, 'No, we don't have a 47 jersey.' I said, 'OK, I'll take 19.' He goes, 'Well, someone else already has it.' I said, 'Just give me a number.' So he gave me 5. Then I showed up to Reno and I just had 17. I was like, 'OK, I guess I'll wear 17.' Hopefully I can get my college number back at some point. Numbers don't mean that much to me."
That would appear to be the case, as he went through a couple during his time at UCLA.
"I had 11 my freshman year," he said. "One of my teammates from high school came to UCLA. He has a twin sister, they've both worn 11 the whole time. She plays softball at Tennessee. I gave him 11 and took 47, and really, there was no reason behind it."
First baseman Mark Grace and right-hander Brandon Webb are two of the players who have worn No. 17 over the years for the D-backs.
