"He's a pretty serious kid, and rightfully so. And it's not because he's nervous, either," Showalter said.
"I'm sure he's trying to figure out a way to make the club. He's a very attentive listener. He'll get out of this what he needs to get out of it and get on with his season. He's a good-looking young man in more ways than one."
Showalter stressed that Bundy won't make the club. Don't get any ideas.
"We are going to deliver him healthy, hopefully, down to that (minor league) camp and he can get ready for his season," Showalter said.
"His train will get moving a little later."
"He's good," Showalter said. "He's got a lot of respect for the level here. You can tell he's been around baseball. He's a very polished young man."
Meanwhile, Showalter repeated that he views Japanese left-hander Tsuyoshi Wada as a starter.
"I like him," Showalter said. "He has a good look on his face. I have a lot of respect for his veteran status and things he's accomplished in Japan. You look at his track record and things he's been the best at over there. It's pretty impressive, so I have a lot of respect for that.
"I'm going to sit down with him (Monday). It's been a hectic day for him - physicals and the meetings we had on this and that, and the first day on the field. I want to leave him alone. He'll have a lighter day tomorrow. We'll sit down and I'll let him know that I've done some homework on his background. And I want him to have some input on what he thinks is best, too, and how he's been handled and treated, too."
Showalter challenged Mark Reynolds after the season to lose some weight, and the third baseman is noticeably lighter in camp.
"It was up to him. I think it's going to help him in a lot of ways," Showalter said.
"He played inside in Arizona and I think a lot of people underestimate the challenge of playing in Baltimore in mid-summer. Mark did some things very well statistically last year, and we both feel very strongly that he's better defensively than he showed last year, and I think that has a lot to do with it.
"I challenged him somewhat and he took it and ran with it. And I really respect that."
Showalter isn't concerned about Reynolds losing power, saying the third baseman dropped 12-15 pounds over the course of last season and still drove the ball.
Reynolds worked out with new special assistant Brady Anderson this winter.
"Brady did a great job with a lot of these guys," Showalter said. "I can give you about 10 guys who you can really tell he did something with."
That includes pitcher Tommy Hunter.
Showalter on Brian Roberts: "He's having a lot more good days than challenging days, so we'll see."
