Scouting grades: Fastball: 55 | Slider: 50 | Changeup: 55 | Control: 45 | Overall: 45

There’s only been one player to make it to the big leagues out of Alhambra High School in Martinez, Calif.: Robert Stephenson, a Reds first-rounder in 2011, who saw eight seasons at the highest level. Millar isn’t expected to rise into the opening round like his predecessors did, but the Alhambra product did have a big up arrow next to his name as he progressed during his senior season of high school.

Over the summer at events like the Area Code Games, Millar was throwing his fastball in the 92 mph range more often than not. This spring, he’s seen a big spike in his velocity, and he’s been up to 97 mph consistently every start, throwing his heater with 20 inches of inverted vertical break. His changeup has been a quality second offering, and while there’s been some question about the quality of spin and bite on his slider, he moves it well from side-to-side; some think there’s an above-average breaker in there eventually as well.

Millar has shown some strike-throwing ability at times, but his arm isn’t always on time in his delivery, leading to an erratic release and inconsistent control. But the Arizona recruit went from being a kind of vanilla high school right-hander to one of the hottest prep arms in the west.

Millar’s stock rose quite a bit during his senior season at Alhambra HS in Martinez, Calif., and the Royals jumped at the chance to get him in the third round of the 2025 Draft. He signed for an over-slot $1,497,500 bonus to keep him from an Arizona commitment. Millar didn’t go out to affiliate ball after he was drafted, but he did pitch in the organization’s instructional league games in the fall.

Similar to a lot of prep pitchers the Royals have drafted recently, Millar is young and raw with intriguing stuff that needs development. His fastball was in the low-to-mid-90s in high school until it spiked to 97 mph his senior year, and the Royals have seen that velocity recently, along with good ride. Millar’s slider hovers around 83-85 mph and is more bullet-like and not quite average yet. His changeup was his best pitch in high school, a low-80s offering with lots of tumble. He’s working on throwing it from a more consistent slot, and one of his cues is to throw it harder and more like his fastball. Millar pitches from a higher slot. although there’s some inconsistency he’s working on, but it’s mostly a clean delivery with a quick arm. He went to the Royals’ strength and conditioning camp over the offseason with hopes that some of the benefits could be found in his delivery and velocity.

Millar’s development will be a slower one, but it’ll be as a starter to begin his career with the potential for a mid-to-back-end rotation member there. He gets high marks for his competitiveness on and off the mound.
