Out of Sierra Canyon, 2027 third-basemen and catcher Aiden Jahng stands 5-foot-11, 201 pounds, carrying a big, proportional build with a notably strong lower half. At the plate he works from a compact leg-kick, cocking his hands back before exploding through the zone. He catches the ball out in front, with a quick lower half and a two-hand finish. The swing produced what was arguably the day's best batting practice showing, 6 home runs across 12 total swings. The numbers backed up the eye test: a 90.2 mph average exit velocity, a peak of 101.3 mph, a long ball of 389 feet, an 80% hard-hit rate, and an impressive 86.7% sweet-spot rate. Behind the dish, he posted a 77 mph catcher velocity with pop times in the 1.95-2.02 range, and flashed that arm in person by gunning down a runner trying to steal third. Game action was quieter, as he went 0-for-1 with a four-pitch walk, followed by a called strikeout on a slider. The in-game reps didn't go his way, but the workout was more than enough to set him apart at the event.
