MILWAUKEE -- What's in a number? For D-backs right-hander Trevor Bauer, apparently not a lot.

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.

Bauer expects to make start on Tuesday

MILWAUKEE -- Trevor Bauer was still dealing with tightness in his groin muscle on Friday, but both the right-hander and manager Kirk Gibson said the injury should not prevent him from making his scheduled start Tuesday.

"He seems to be able to pitch with it," Gibson said. "We've tested it; he's strong as a bull. He's very, very strong. That's encouraging. I expect he'll be able to make his next start."

Bauer has dealt with the issue on and off throughout the year. It flared up in the third inning of his debut on Thursday, and he said it caused him to alter his mechanics and therefore impacted his command.

"A lot of hip repositioning stuff to try to take off some of the pressure and some soft tissue stuff to get some of the swelling out of there and get it to calm down a little bit," Bauer said of the treatment he received Friday. "It's been worse in [Double-A] Mobile and I never missed a start. I'll be fine."

It has been a whirlwind few days for Bauer, who is still trying to get acclimated to the big leagues. The fact that Major League teams travel via charter aircraft as opposed to flying commercial flights like they do in the Minors is a big perk. So is the fact that in the Majors players get their own hotel rooms on the road, whereas they have to have a roommate in the Minors.

"I'm still trying to figure the whole routine out," he said. "Parts have settled in. It's nice knowing guys from Spring Training, for sure. Last year, when I went to Mobile, the first time I met the guys, and when I went to [Class A] Visalia [last year], it was the first time I'd met the guys. I definitely feel more comfortable now that I know some of the guys from Spring Training and I can shoot the breeze with them. It makes things easier."

Before being called up, Bauer had to incessantly answer questions about when he thought he might be promoted. As of Thursday, his online interaction with fans changed.

"Now I have people on Twitter telling me I let their fantasy team down," Bauer said with a smile. "Whole new set of issues. It's nice, though I try to keep myself away from all that and focus on what I can control and pitch. It's tough.

"Obviously, I do enjoy going on Twitter and interacting with fans and stuff like that. I see what people are saying, good, bad and indifferent. It's something I want to continue doing, be kind of fan accessible and answering questions and stuff like that. It's always going to be there. I just hope to find a way to regulate it and be able to shut it off when I need to get my work done."

Skaggs added to Futures Game roster

MILWAUKEE -- Tyler Skaggs will be one of two participants to represent the D-backs in the Sirius XM All-Star Futures Game.

Skaggs replaces Trevor Bauer, who was called up to the big leagues on Thursday, and joins outfielder Alfredo Marte in representing the Arizona organization.

Skaggs, who is pitching for Double-A Mobile, will play on the U.S. Team, while Marte, who also plays for Mobile, will play for the World.

This will be Skaggs' second straight appearance in the game.

"So blessed to be able to go to the [Futures Game] again!" Skaggs tweeted. "Can't wait to get to KC. Another dream come true."

Worth noting

• Left-hander Joe Saunders (shoulder) is scheduled to throw a light bullpen session on Saturday, and if that goes well, he will throw 50 pitches in a simulated game on Tuesday at Chase Field.

If Saunders comes through those tests, the plan is to have him make one Minor League rehab start.

"He should be good to go after that," D-backs manager Kirk Gibson said. "[Right] after the All-Star break. That's the wish. I don't see it getting sped up. It's possible, but that's kind of the plan as of today. Things can change."

• After playing two days in a row, shortstop Stephen Drew was out of the starting lineup on Friday.

"I kind of planned on not playing him today anyway, so hopefully he'll be ready to go tomorrow," Gibson said. "We just want to work him back into it at a reasonable pace."

Drew, who played Wednesday for the first time since last July 20, said he was feeling pretty good and expected to be back in the lineup Saturday.

• The D-backs signed a four-year contract renewal of their player development contract with their Triple-A Reno affiliate.
