Body: 5-foot-11, 175 pounds. Athletic infielders build with baseball athleticism. Moves around the infield naturally and shows some twitch at the plate. Ability to play multiple infield positions and pitch show his natural ability on the baseball field. 

Hit: Right-handed hitter. Hitting set up; stands athletic and loose, keeps hands shoulder height and back, loads with a leg lift and some coil, hands work quickly - passing the quick hands eye test, bat shows that it stays on plane, hips clear quickly. Bat speed averaged 66.8 mph and rotational acceleration average of 21.1 g, according to Blast Motion. Bat speed metric currently shows that he is able to propel his bat at contact at the average ideal range at the college level. Flores rotational acceleration is well above the MLB average of 17 g at 22.1 g, 4th highest of the 24 hitters tracked at the ProCase. Flores also posted the 2nd highest Rotation score out of the 24 hitters tracked at the ProCase. The rotational acceleration metric shows that Flores bat is able to reach peak speed at a well above-average speed, showing that he sufficiently uses his hips and torso well to generate speed. The Blast Motion rotation score doubles down on the rotational acceleration metric by showing Flores above-average ability to sequence correctly, make in-swing adjustments and elite ability to check his swing. Flores’ also posted a 86% on plane efficiency swing metric, well above the desired 70%. 

Power: Trackman data shows that his average exit speed is 86.28 mph, with exit speed contact averages to inside and outside pitches relatively even across the board with slight average gains on inside pitches. Personal best exit speed of 89.80 mph with a launch angle of 26.70° at 337ft. Showed off some present line drive pop with a double to left-center field in the live at-bat portion of the ProCase. Flores' above-average rotational acceleration metric shows that his hands are projectable and can evolve with higher velocities, thus indicating more power to come down the line. 

Field: Slick fielding infielder with the kind of actions that have become common in Southern California infielders over the years. Prep steps before each grounder or pitch to set himself up athletically for wherever the ball is hit. Keeps his body and glove low to the ground helping enable his lateral quickness and help put his body in a good throwing position. Quick hands at the plate transitioned onto the field as well as he showed off clean quick transfers and the ability to get rid of the ball quickly. Charged the ball well, displayed lateral quickness and average overall range. 

Arm: Infield arm velocity reading of 72 mph, 10 out of 10. Showed a quick release and poor throwing mechanics. Keeps his hand close to his body and glove helping enable his quick release. Made throws from multiple arm angels. Throwing motion looked strained and the low infield velocity reading was a surprise. Also known as an effective pitcher with a fastball clocked as high as 86 mph, the ProCase poor infield arm showing could have been due to lack of play from the High School season shutdown or from injury. 

Run: 7.28 60 yard dash. 

Summary: Flores’ above-average swing metric readings in rotational acceleration and on plane efficiency are clear indicators of why he is a successful hitter and great for down the line hitting projections. These types of swing metrics show that his bat currently possesses tools to succeed at the collegiate and professional levels. The arm tool is in question and could force him to the right side of the infield, where his infield skills will play up along with his bat. The bat alone will garner him professional scouting interest in the 2021 season but time in an Aztec uniform to develop more as a hitter could really propel him down the line in the professional scouting circles.

OC Preseason All-State: After a standout showing to end the summer at the California State Games followed by an equally good fall with the SoCal Athletics Scout Team, Flores came to the Preseason All-State ready for what should be a huge junior season for the silky smooth shortstop who can pitch and help Cajon win games there too. Showed continued consistency with his barrel control during BP where favored the big part of the field. Twitchy strength throughout his frame. Manipulated barrel plane well. On the mound Flores showed at least average command of three pitches with nothing straight out of the hand. Arm can get long in back at times causing his mechanics and timing to go awry, a sign of lack of work as a pitcher maybe. Fastball worked 84-86 mph, while his curveball worked 76-78 mph with both flashing side-to-side movement. Change has developed significantly since last summer while maintianing it’s velocity at 76-78 mph. 


PBR CA STATE GAMES - Medium, full frame with strength and athletic actions showing two-way skills that can carry over to the next level. Worked three innings over two days holding velocity and striking out 7 over the three innings. Hands break hard on front leg as he rides his back leg down the hill allowing loose arm to be compact out of the glove with an efficient elbow spin; athletic delivery and attacked the zone. FB 83-86 with heavy armside run and cut; drops down some having late run on the RHH’s. CB 74-77 having different breaks over the two days with feel of the pitch; blended between a 12/6 with short depth into and through the zone to a harder slurve (12/4 shape) that stayed tight and looked to bury. CHG 76-78 was late at the plate with bottom and feel setting up the FB and BB. At the plate showed a compact bat with plus hand speed after high front knee kick; bat stays in the zone forever with late whip upon contact out front as he picked up multiple hits seemingly always on base. One of the top 2021 players in the state.
