Kossi Milner: SS/2B, (2025) Cambridge Rindge and Latin School, MA. 5-foot-9, 165-pound athletic lean frame. Athletic and projectable at the plate, the right-handed hitter's best exit velocity was 87 mph. (68.1 mph bat speed average). (22.3 mph hand speed average). Began in a balanced athletic stance with a low load, then used a toe tap short stride. Bat speed is developing, exhibits an uphill loose swing plane and good extension on his finish. He barreled up multiple balls with loud contact. Gap to gap aggressive approach. Athletic projectable while in the infield, made throws up to 78 mph; had developing athletic footwork, developing soft hands, and a natural exchange. Fields the ball out front, movements laterally were developing athletically. Used a loose arm action and a high ¾ slot while showing consistent accuracy to the base. Established speed as one of his strengths with an efficient 60 time of 6.87. (Max spin ; Avg ).
