San Francisco Giants: Midseason Top 30 Prospects (Nos. 10-1)

2. SS Marco Luciano

Age: 17
Current Level: Arizona Rookie League
Acquired: IFA (2018)
Future-Value Grade: 50

Luciano has the highest ceiling in the San Francisco Giants system. In fact, he may have one of the highest ceilings in baseball.

Like Heliot Ramos, he has a football player’s build and is a powerful athlete, able to generate 70 to 80-grade bat speed. That kind of power alone would make him an intriguing prospect, but he also has a solid chance to stick at shortstop defensively.

Since he doesn’t have to sell out to do damage, there’s hope that Luciano will be able to develop an above-average hit tool along with his power, but that won’t be necessary to contribute. After signing just last summer for a $2.6 million bonus, the Giants aggressively sent Luciano stateside to make his debut and he hasn’t disappointed.

After a strong first week, Luciano has maintained an elite level of productivity over his first 15 games. If he keeps this up, he may force his way onto the Low-A Salem-Keizer roster before long.

Regardless, he appears destined for Single-A next season, which will put him on a developmental path similar to Ramos.
