Scouting grades: Fastball: 70 | Slider: 55 | Control: 40 | Overall: 45

All summer long, Sime Jr. showed off what scouts like about him, namely his arm strength, and what concerns there are, namely his command. The New York City native who attends Poly Prep announced his presence with authority at events like East Coast Pro Showcase and PG National but often struggled with finding the strike zone. At the Area Code Games, he walked the bases loaded, then struck out the side, which looked like he was turning a corner. That trend continued when he largely filled up the zone and struck out two at Major League Baseball’s High School All-American Game and he showcased similar stuff, and a little better feel, this spring, including at USA Baseball’s National High School Invitational.

A participant in MLB Develops programs like the Breakthrough Series and Dream Series, Sime has been lighting up radar guns for some time. He averaged over 95 mph with his heater throughout the summer and is routinely up to 98-99 mph, touching triple digits at times, and he’s been reaching those elite-level velocities this spring. The pitch has serious life to it, and he can sink it, with one scout calling him a “pure rock thrower.” The pitch can be so devastating that he hasn’t always needed anything else, but he’s worked hard on his breaking ball. He has feel to spin a 78-81 mph hard slider, landed a good one in the zone in the All-American Game and seemed more comfortable with it during his senior season. 

The biggest thing holding Sime back is his ability to consistently land his power arsenal in the zone. It was better at the end of the summer and for much of the spring, and it’s clear he understands he needs to improve that and the consistency of his secondary stuff to move up boards. Likened to a better-conditioned Armando Benitez, Sime is committed to Louisiana State should the Draft not work out.

After a turn in the MLB Draft League, he went to the Nationals in the third round and signed for $2 million.

A participant in MLB Develops programs like the Breakthrough Series and Dream Series, Sime has been lighting up radar guns for some time. He averaged over 95 mph with his heater throughout the summer and was at 96-99 mph in short spurts in the MLB Draft League, touching triple digits five times. The pitch has serious life to it, and he can sink it, with one scout calling him a “pure rock thrower.” The pitch can be so devastating that he hasn’t always needed anything else, but he’s worked hard on his breaking ball. He has feel to spin a low-80s curveball -- landed a good one in the zone in the All-American Game -- and seemed more comfortable with it during his senior season. There’s also an 85-88 mph changeup that he’ll need to develop a feel for in pro ball.

The biggest thing holding Sime back is his ability to consistently land his power arsenal in the zone. It was better at the end of the summer and for much of the spring, and it’s clear he understands he needs to improve that and the consistency of his secondary stuff to move up the ladder toward Washington.
