SAN FRANCISCO >> The song has paused in the game of musical shortstops and Marco Luciano doesn’t have a seat.

When the Giants signed Nick Ahmed, they always intended the veteran shortstop to serve as a stopgap. But instead of handing the keys to their top prospect after another half-year of seasoning at Triple-A, the club’s cutting ties with Ahmed this week was prompted by the emergence of other young players.

“We’re pretty comfortable with what we have at shortstop right now,” manager Bob Melvin said Wednesday, referring to Brett Wisely, 25, and Tyler Fitzgerald, 26, who are expected to share the duties moving forward. “Wisely’s just done a fantastic job moving from second to short. He’s swinging the bat well, too, and an infusion of energy.”

Luciano, who turns 23 in September, remains at Triple-A Sacramento, where he has been since a hamstring strain ended his tumultuous first tenure in the big leagues this season. He is no longer playing exclusively shortstop, spending time at second base since being activated off the injured list on June 13.

Despite Luciano being passed over for a promotion and moved off his primary position, his stock hasn’t taken a hit in the Giants’ eyes.

“Nobody’s jumping to conclusions based on a short stretch and a handful of tough plays that didn’t go his way,” president of baseball operations Farhan Zaidi said Tuesday. “Some of this is just his philosophy of finding different spots to get guys to the big leagues when we have opportunities. Diversifying things a little bit for him has made some sense.

“But we’re not giving up on the shortstop role for him.”

The emergence of Wisely and Fitzgerald isn’t such a bad thing for an organization that was able to count on one man, Brandon Crawford, at the position for 13 years and possessed the depth you might expect behind such reliability. They cycled through players such as Donovan Walton, Dixon Machado, Johan Camargo, Mauricio Dubón, Paul DeJong and Casey Schmitt before settling on their current duo.

Luciano has been earmarked as Crawford’s eventual successor since he signed as a 16-year-old out of the Dominican Republic for a $2.6 million bonus. But even after the symbolism of having him replace Crawford for the final inning of their last game of 2023, the Giants brought in Ahmed to challenge him in spring training. The defensive-minded veteran went on to win the Opening Day job.

With Ahmed sidelined earlier this season, the Giants handed the reins to Luciano, who, according to Zaidi’s frank assessment, “had one of the roughest weeks defensively that a lot of us have seen.” He committed five errors in five games, four in the ninth inning or later, prompting Melvin to shift Wisely from his natural second base to shortstop.

Over many more games in the minor leagues, the defensive metrics the Giants consider have rated Luciano’s play at shortstop more favorably, Zaidi said.

“So over big samples he’s done a nice job,” Zaidi said. “It’s always going to be different when you come up here, the pressure and expectations and being able to do it on a night-in, night-out basis on a big stage. That’ll be a hurdle for him, but we’re going to continue to get him reps (at shortstop).”

Luciano has made nine appearances this season at second base, compared to 44 at shortstop. While it hasn’t been the smoothest season from an offensive perspective for Luciano, batting .230 with a .681 OPS in the hitter-friendly Pacific Coast League, the Giants don’t have any doubts about his potential at the plate.

The more pressing questions are when he gets his next chance in the majors and what position he’ll be playing.
