GLENDALE, Ariz. -- The first 2023 Spring Training complaint White Sox general manager Rick Hahn received came from a concerned Joe Kelly.

It dealt with left-hander Noah Schultz, the team’s top pick in the 2022 Draft and its No. 4 prospect, per MLB Pipeline.

“He asked me why Noah Schultz wasn't in big league camp because he has better stuff than Joe -- which made me worry about Joe a little bit,” Hahn said with a laugh.

Schultz, 19, is in Arizona taking part in Minor League Spring Training. He's been in town since mid-January when arriving for prospect minicamp. The 6-foot-9, 220-pounder, who has already drawn exciting comparisons ranging from Chris Sale to Randy Johnson without throwing in a Minor League game, has been halted this past week due to soreness caused by a left flexor strain.

This issue is “nothing crazy,” per Schultz, who expects to start throwing again soon.

“It’s working in a good direction,” Schultz told MLB.com during a recent interview. “Been working in the training room, getting help from the trainers.

“They have been amazing. The weight room, the trainers there, they have been helping with everything, modifying workouts and such. Everybody has just been great and I’ll be back out soon.”

During this brief hiatus, Schultz has watched live batting practice sessions and stayed as connected as possible to his work and his teammates. The injury slowdown is not really a bad thing in the big picture, since it’s minor and Schultz’s innings were already going to be monitored during this first professional season.

After going through instructs, where Schultz made a major impression during a dominant two-inning stint against the Dodgers, nothing has really been unexpected for him during Spring Training.

“I’d say there are more people, but I would say it’s the same structure somewhat,” Schultz said. “Our schedule we have is really nice and thought through well. Everything we do is trainers and people helping -- they do a great job of making sure everything is OK. Asking how we feel every day, which is great to be around these people, especially before a season.”

Fans already have taken to Schultz and the promise of his vast potential. He sees them every day as he’s walking to the back fields at Camelback Ranch, viewing their support as a cool thing to show how hard work has paid off so far and “just to show putting in hard work every day … the sky is the limit.”

A family who watched Schultz when he pitched for the Illinois Valley Pistol Shrimp in the summer Prospect League made the trip to Arizona and stopped to talk with the southpaw.

“Just to meet up and catch up with the guys,” Schultz said. “I didn’t personally know them, but they said they were at some of my games this summer.”

Those fans enjoyed Schultz’s work, but probably don’t have the same appreciation for his talent as Kelly. The veteran right-handed reliever worked four or five days per week at Camelback Ranch during the offseason and watched Schultz throw multiple times.

“I knew it was good,” Kelly said. “Then I watched him throw when we both got in the lab and the numbers he puts up would be the best on our team. When you take into consideration movement, when you take into consideration spin, when you take into consideration velocity, approach angle, length -- literally, he’s better than me already. There’s nobody who can repeat 6-foot-9 and 22 inches on fastball, 22 inches on slider, 22 inches on three elite, elite, elite pitches.”

“It’s always cool to get praise from guys, and he’s a cool guy, a good person to look up to,” Schultz said. “Still lots of work to do, lots of ways to get better every day.”

Kelly wanted Schultz in big league camp for the valuable learning experience. Even if he didn’t pitch, Schultz would talk with guys who knew what it takes to be at the big league level and watch other starters’ workouts as someone relatively new to the craft.

“When I was young, when I went to big league camp, every first-rounder was in big league camp even if they were in high school,” Kelly said. “Shelby Miller was 18 years old and went to big league camp right away when he was with the Cardinals and I was there.

“He’ll get his chance probably next year. But yeah, he’s going to be something special. It’s pretty cool to see.”
