PHOENIX -- Jordan Lawlar is about to complete his rapid ascent to the Major Leagues.

The D-backs called up their top prospect from Triple-A Reno after their 12-5 victory over the Rockies on Wednesday afternoon. He will join the team in Chicago, where Arizona will play the Cubs in a crucial four-game series with major Wild Card implications.

D-backs manager Torey Lovullo made it clear that Lawlar isn’t just here to get a taste of the Majors; the skipper said the 21-year-old is coming up to help Arizona reach the playoffs for the first time since 2017.

“He'll be the starting shortstop,” Lovullo said. “And then I just want to inject him into the lineup when I can for the right matchup in the right situation.”

Lawlar was drafted sixth overall out of high school by the D-backs in the 2021 MLB Draft, when he was the No. 10 overall prospect. Scouts cited his advanced pitch recognition, plus speed and all-fields power. Lawlar slashed .278/.378/.496 with 20 homers and 36 steals between Double-A Amarillo and Triple-A Reno this season.

Rookie sensation Corbin Carroll had a wide grin when he found out about Lawlar’s promotion during a postgame interview, and the 2023 National League Rookie of the Year Award favorite had some words of advice for his new teammate.

“I think he just needs to come up here and be himself,” Carroll said. “I think he has a lot of resources here … a lot of veteran guys and then some young guys as well who share experiences with him. I think he's going to be in a great spot.”

The D-backs made four corresponding moves in response. Nick Ahmed, Arizona's longest-tenured player, was designated for assignment, ending his 10 seasons with the club. Lovullo broke the news to Ahmed after the game.

“He left everything he could possibly have out there on this field.” Lovullo said. “He's had some unbelievable moments, it didn't end the way we wanted it to. My thought was to make him my first embrace when we clinched a playoff spot this year because of everything that he's been through, we've been through and this organization has been through. But we'll just put that on pause.

“That obviously hits me a little bit harder than some, but baseball's tough sometimes. But it happens and we've been a part of it, and we'll move on. He'll move on.”
