With a top prospect rostered, who will start at shortstop for the Diamondbacks?

The Diamondbacks head into 2024 with a pair of intriguing young shortstops. Arizona carried both Geraldo Perdomo and top prospect Jordan Lawlar on last year’s playoff roster. Perdomo held the job throughout the postseason and will continue in that role for the upcoming year.

“Perdomo is going to be our starting shortstop,” manager Torey Lovullo declared from the team’s Spring Training complex this week (relayed by Alex Weiner of Arizona Sports and Steve Gilbert of MLB.com). “He’s earned that right. I know he has worked very hard on his right-handed swing. … He deserves the opportunity to show me he’s able to handle a full workload as an everyday shortstop.”

Perdomo was an All-Star last season at age 23. He earned that nod with an impressive .271/.378/.409 batting line through the first half. Perdomo’s offensive production cratered down the stretch, as he hit .214/.322/.297 coming out of the All-Star Break. It looked as if that mediocre finish could at least open the door for Lawlar to seize the job, but the D-Backs are clearly bullish on Perdomo’s ability to rebound.

Overall, Perdomo is coming off an impressive year. His .246/.353/.359 line is right around league average. Perdomo drew walks at a strong 12.9% clip while striking out less than 18% of the time. His offense bounced back in October, as he turned in a .275/.362/.392 slash in 17 playoff contests. Perdomo logged nearly 900 regular season innings at shortstop. Defensive Runs Saved graded him slightly below average, while Statcast’s defensive marks had him just above par.

As Lovullo implied, one of the biggest remaining questions is whether the switch-hitting Perdomo can do enough damage from the right side of the plate. He didn’t hit for any power against left-handed pitching a year ago, running a .242/.304/.274 line in 71 plate appearances. Perdomo showed gap power as a lefty bat, collecting 18 doubles and six homers with a .246/.362/.374 slash.

It seems he’ll get a chance to prove he’s capable of handling pitchers of either handedness. Barring injury, it’s likely that means Lawlar is headed back to Triple-A Reno to start the year. Arizona acquired Eugenio Suárez to play third base and has Ketel Marte locked in at second. They signed Joc Pederson to take the bulk of the DH at-bats. There’s no path to regular playing time on the infield if everyone’s healthy. Arizona certainly won’t want Lawlar playing sparingly in a utility capacity.

The 2021 #6 overall pick could benefit from additional reps at the top minor league level. Lawlar barely played in Reno before Arizona called him up last September. He had just 16 games of Triple-A experience. The right-handed hitter spent the majority of the season at Double-A Amarillo. He turned in a stout .263/.366/.474 line with 15 homers and 33 steals over 89 games there in his age-20 campaign.

Reno’s extreme hitter-friendly nature can throw a wrench into the evaluations for Arizona prospects on both the position player and pitching sides. That’s probably not much of a concern with Lawlar, though, as he remains a consensus top-tier talent. He placed among the sport’s top 10 prospects on recent lists from FanGraphs, Keith Law of the Athletic and Baseball America. ESPN’s Kiley McDaniel slotted him in the top 20.

If Lawlar starts the season in Reno, Emmanuel Rivera and Jace Peterson project as the depth infielders. Neither is a great fit at shortstop, so the Snakes could add a glove-first middle infielder to back up Perdomo and Marte. Minor league signee Kevin Newman fits the bill and is trying to crack the MLB team as a non-roster invitee in Spring Training.
