Uncommitted. 6-foot, 170 pounds. 2023 Junior Future Games alumni. Alonso flat-out rakes, had a hot summer and has continued that into the fall. Tall, athletic frame with proportional strength. Small hand load with good hand speed and a toe tap in stride. Simple, repeatable swing. Alonso is simply a gamer and a can’t-miss hitter wherever he is. Also had an inside-the-park grand slam during the tournament! Looking forward to see Alonso continue to show out this fall.
Alonso started on the bump today for team Georgia going 2 IP with 1 K and limiting Louisiana to two runs.He has a ¾ AA with mid depth. Alonso pounded the zone with his FB and threw an occasional CH to keep hitters guessing. Alonso has an EZ, repeatable delivery that gets on hitters quick. Alonso also barreled in a couple of RBIs for Team Georgia in the first. 6-foot, 170 pound frame with a small hand load and toe tap in stride. Strong wrists with a powerful upper half for age. Barreled a 2-run RBI triple, 94 EV(Drop 5), to extend Georgia’s lead to 3-0.
