TOP PERFORMERS 

Keith Clark OF / 3B / Madison High, CA / 2028 Rankings  StateRank: 201 / POS: 43 Clark had a strong 2026 spring, and that continued on Saturday, highlighted by an event-best 91 mph outfield arm and a 6.98 60-yard dash. The physical 5-10, 198-pound left-handed hitter also posted a 99.7 mph max exit velocity (3rd best), 389-foot max batted distance (tied for 2nd), and 78.9 mph max bat speed (top five). Clark works with a consistent uphill swing path, looking to drive the baseball from left-center to right-center field, producing a 50% line-drive rate and 30% fly-ball rate during BP. The offensive approach has translated well into live gameplay in previous looks this past spring, and the combination of present strength, left-handed impact, and arm strength gives Clark an intriguing profile leading into his junior season at Madison.

Sebastian Flores OF / 1B / LA Jolla Country Day School, CA / 2029 Flores showed an intriguing combination of left-handed bat-to-ball ability and present strength during Saturday's workout. The physical 5-11, 202-pound sophomore displayed a smooth, low-effort left-handed swing with natural barrel control, consistently working on a line to all fields. Registered a 95.1 mph max exit velocity with a 352-foot max distance, while producing 22.5 mph average hand speed and 78.7 mph max bat speed. Flores also ran a 7.15 60-yard dash and showed solid arm strength from the outfield, reaching 86 mph (3rd best). The combination of controlled swing mechanics and present physicality gives Flores an interesting offensive profile to follow in the 2029 class.

Owen Martinson-Fuller C / 3B / Rancho Bernardo High, CA / 2028 The Rancho Bernardo native put together a strong two-way showing on Saturday, with his bullpen performance standing out as one of the more impressive of the event. The physical 5-8, 233-pound junior worked his fastball 87.9-89.8 mph (event best) with an average 6.5 feet of extension, pairing it with a firm 77-81 mph slider that reached 2,448 rpm and a 76-80 mph changeup with low spin (897 rpm) and fading action. Behind the plate, Martinson-Fuller showed noticeably improved arm strength from the summer, reaching 80 mph with 2.01-2.12 pop times. Offensively, the uncommitted product registered a 93.6 mph max exit velocity and 363-foot max distance.

Logan Allport 1B / OF / Patrick Henry High School, CA / 2028 Allport delivered one of the loudest offensive workouts of the event, leading the field in both max exit velocity (105.6 mph) and average exit velocity (102.2 mph). The physical 6-2, 190-pound left-handed hitter posted a 100% hard-hit rate with a 389-foot max distance, consistently driving the baseball on low, hard lines with minimal fly-ball contact. The junior also showed solid athleticism for his size, running a 7.07 60-yard dash and reaching 89 mph from the outfield. While the offensive metrics ranked among the best across multiple categories, it will be intriguing to see how the present strength, impact potential, and left-handed swing translate into live game action this upcoming spring at Patrick Henry.

Matthew Parker RHP / 3B / Rancho Bernardo High, CA / 2029 Rankings  StateRank: 38 / POS: 9 OverallRank: 270 / POS: 57 Parker burst onto the scene as a freshman in 2026, establishing himself as a reliable arm for Rancho Bernardo's pitching staff, and Saturday's showing offered another encouraging look at his development. The 2029 right-hander worked his fastball 83.9-85.2 mph, topping at 85.4, with an average 90% spin efficiency, while showing a sharp 74-76 mph slider that reached 2,648 rpm. The 76-78 mph changeup remains a standout offering, showing heavy drop and fade similar to what made it particularly effective against right-handed hitters during the spring. Parker also showed offensive upside with a 97.0 mph max exit velocity, 22.0 mph average hand speed, and 83 mph across the infield. With noticeable physical development since his freshman season and the potential for increased everyday at-bats as a sophomore, Parker has the ingredients to emerge as one of San Diego's more intriguing two-way talents in the 2029 class.

Isaak Perez 3B / C / Montgomery Senior High, CA / 2027 Perez put together one of the more impressive offensive workouts on Saturday, highlighted by arguably the loudest swing of the entire event, a towering drive that traveled 419 feet. The physical 5-10, 236-pound senior registered a 104.0 mph max exit velocity, 94.3 mph average exit velocity, and 71% hard-hit rate. Perez works with a modest, controlled swing but generates considerable torque through the zone, creating an uphill path that produced a 71.4% fly-ball rate during BP. Behind the plate, Perez recorded 2.11-2.24 pop times with a 73 mph catcher velocity. Having already impressed our San Diego staff during live looks throughout 2026, Perez continues to show legitimate offensive impact and looks poised for a strong senior season at Montgomery.

Liam Ryan OF / RHP / Helix, CA / 2029 Ryan brought a mature offensive approach and considerable physical projection to Saturday's workout, standing at an impressive 6-5, 202 pounds after recently turning 16 years old. The Helix sophomore registered a 98.2 mph max exit velocity and 90.4 mph average exit velocity, showing a mostly level swing path with occasional steepness through the zone. While some of the offensive metrics did not necessarily jump off the page, Ryan showed a controlled approach during BP with an understanding of how to use the present length and leverage in the frame. With plenty of room for continued physical development, Ryan presents an intriguing long-term offensive profile as his strength and overall swing mechanics continue to mature.

Eddie Lucero RHP / 3B / Mission Hills High, CA / 2027 Lucero turned in a strong bullpen showing on Saturday, consistently filling up the strike zone from a low three-quarter arm slot. The physical 5-11, 188-pound right-hander showed intriguing fastball movement with 14.1 inches of horizontal movement and peaks of 16.4 and 15.9 inches. Lucero complemented the fastball with a 73-74 mph curveball and a 75-76 mph splitter that featured low spin (711-877 rpm) and fading action, giving him a distinct off-speed look in the bullpen.

Brandon Hirsch 3B / 1B / LA Jolla Country Day School, CA / 2029 Hirsch showed noticeable improvements in barrel control since the San Diego Summer ID in June, putting together one of his more consistent BP rounds in front of our staff. The La Jolla Country Day sophomore was consistently on the barrel, registering a 96.3 mph max exit velocity, 90.3 mph average exit velocity, and 71% hard-hit rate. The quality of contact was reflected in a 43% line-drive rate and 42.9% fly-ball rate, showing the ability to produce both hard contact on a line and carry through the air. Hirsch also ran a 7.24 60-yard dash and reached 81 mph across the infield.

Xander Moreno OF / OF / Beaumont Senior High, CA / 2028 Moreno's athleticism and quick-twitch ability immediately stood out on Saturday, highlighted by an event-best 6.67 60-yard dash. The Beaumont junior possesses an athletic frame with explosive movements, pairing his speed with intriguing offensive tools. Moreno registered a 98.1 mph max exit velocity, 372-foot max distance, and 77.3 mph max bat speed, working with a short, compact swing that shows the ability to generate impact without excessive movement. Defensively, Moreno reached 83 mph from the outfield, consistently delivering low, accurate throws on a long hop. With an impressive combination of speed, athleticism, and developing offensive impact, Moreno looks to be coming into his own as an intriguing 2028 outfield prospect heading into his junior season.
