FULLERTON, CA. - Sebastian Pollo Flores showed off classic Southern California short-stop feel and posted impressive swing metrics at the 2020 SoCal ProCase. The three-year letter winner came into the ProCase with impressive career varsity offensive numbers in 230 plate appearances; 333 batting average, 908 OPS, 42 R, 33 RBI, 23 XBH, 20/21 SB. On the mound; 51 ⅓ INN, 2.86 ERA, 1.52 WHIP. Flores is incredibly seasoned as far as playing time goes for a 2021 class player, with the batting average and OPS clear indicators that he is an above-average high school hitter. Thirty-five percent of his high school hits went for extra bases so it came to no surprise when Flores doubled in his first at-bat in the ProCase. 


Flores posted some impressive Blast Motion and TrackMan metrics that will surely check some boxes from the analytical side. It doesn’t take technology to notice his quick hands and ability to use his torso and hips to generate speed. Flores clearly has tools in his swing that project well and will continue to help make him a successful hitter. With 67 representatives from 22 MLB Organizations in attendance, some teams 2-3 deep, and the talent on the SoCal ProCase roster, Flores set out to show that his 55th overall ranking in the state is for real and worthy of draft consideration in 2021 and beyond. 




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.
