Here were your 3 1B in the system and you can see from the highlighted parts why they chose who they did. Groover could maybe make it to third. He's the only one with a chance.
De Los Santos Scouting:
Scouting grades: Hit: 40 | Power: 60 | Run: 40 | Arm: 50 | Field: 40 | Overall: 50
Signed for $200,000 out of the Dominican Republic by the Diamondbacks in 2019, De Los Santos burst onto the prospect scene three years later by winning the Single-A California League batting title (.329) and mashing 22 homers between three levels. His subsequent struggles in the Arizona Fall League after the 2022 season and in Double-A at the start of last year prompted Arizona to put him on the development list for the first two weeks of July so he could rework his right-handed swing. Though he batted .322/.340/.596 afterward, the D-backs left him unprotected on their 40-man roster, and the Guardians pounced on him in the Rule 5 Draft in December. Returned to Arizona in March, he moved on to the Marlins in a July deal for A.J. Puk.
With raw power and exit velocities that rank among the best in the Minors, De Los Santos offers huge power potential thanks to his bat speed and strength but won't come close to fully tapping into it unless he can tone down his approach. Arizona tried to simplify his load and give him more time to make better swing decisions, yet despite his improved performance, he still chased way too many pitches and produced too many ground balls. Even with his flaws, he led the Minors in homers (28), total bases (217) and RBIs (84) at the time of the trade.
Melendez Scouting
Scouting grades: Hit: 40 | Power: 60 | Run: 30 | Arm: 50 | Field: 40 | Overall: 45
A junior-college transfer, Melendez joined Texas for the 2021 season and showed good power with 13 homers but only went in the 16th round to the Marlins that summer. After not signing, he put together one of the most powerful college seasons in recent memory with 32 homers (most in NCAA since BBCOR bat restrictions were adopted in 2011) and led Division I in total bases and slugging percentage on his way to winning the Golden Spikes Award. The D-backs took Melendez in the second round in 2022, and while some questions remain about the entire profile, he lived up to his reputation with 30 homers over just 96 games between High-A and Double-A in his first full season before finishing up with a stint in the Arizona Fall League.
The right-handed slugger has the natural strength for at least double-plus raw power, so much so that coaches have advised him he just needs to “tap the ball” to send it screaming around the ballpark. To wit, he topped out with a 115.5 mph exit velocity in the AFL; only Ketel Marte (117.1) had a higher EV among D-backs Major Leaguers in ’23. Melendez has an uphill swing that creates the loft needed for his high homer total, but that also creates major contact concerns. He had whiff and chase rates above 30 percent on every pitch type he saw at Double-A, including fastballs.
Groover
Scouting grades: Hit: 60 | Power: 50 | Run: 30 | Arm: 45 | Field: 40 | Overall: 50
Groover hit .351 as a freshman at UNC Charlotte in 2021, transferred to NC State the following year and never stopped hitting for the Wolfpack. He produced a .332/.430/.546 line with 13 homers and a 26/36 K/BB ratio over 57 games as a junior last year and was selected by the D-backs in the second round that July, signing for exact slot at $1.783 million. Groover went 23-for-87 (.264) and struck out only nine percent of the time over a 23-game stint with High-A Hillsboro to end the summer.
The right-handed slugger has a quiet and simple stance at the plate, letting his hands do the firing because of their impressive quickness. He manipulates the barrel well, too, helping him make contact against pitches of all types, and he especially feasted on fastballs, whiffing on only nine percent of his swings against heaters in college in 2023. His swing can be grooved, leading to solid line drives across the park, but he has 20-homer upside if he can elevate a bit more.
Groover’s defense was his biggest drawback going into the Draft. Below-average speed made him a first baseman as a freshman and sophomore, and while his fast reactions helped him move to third base last year, he still lacks the range and arm strength (with a short throwing motion) to project as anything more than below-average at the position. His plus bat would hold up at the cold corner, second base or the outfield, where he also got looks in school. It was at first that he suffered a broken left wrist on April 9, an injury that could keep him out for three months of his first full season.
