球探報告：郭宇恩
基本資料 學校：北市重慶國中 守備位置：游擊手 / 一壘手 投打習性：右投 / 右打 身高 / 體重：5呎10吋 / 166.7磅 體型結構均衡且具備潛在的力量增長空間 數據分析 跑壘速度 60碼衝刺跑：7.8秒 臂力與守備 內野臂力速度：69英里 守備腳步：流暢性表現穩定 接球判斷：基本穩定，但在接球面細節上仍有提升空間 打擊數據 Sweet Spot：25% 最快擊球初速：89英里 平均擊球初速：77.7英里 最遠擊球距離：253英尺 擊球類型分佈：飛球50%，滾地50%
綜合評價
郭宇恩具備國中階段少見的身材與力量條件，特別是在打擊數據上的表現，顯示出他具有較強的長打潛力。他的擊球初速表現相對優異，最遠擊球距離也達到了253英尺，展現出其擊球力量的亮點。然而，他在擊球準確性（Sweet Spot）方面需要進一步提升，以增加穩定性與有效擊球的次數。 在守備方面，郭宇恩的腳步流暢，判斷穩定，但接球面的處理仍有可提升的空間。臂力數據中等，在游擊與一壘的角色中尚能應對，未來若能進一步提升傳球力量與精準度，將成為他在內野防守中的一大亮點。 總體而言，郭宇恩在國中階段已具備不錯的基礎條件，身材與數據表現均展現出良好的發展潛力。隨著未來體能與技術的增強，他有望在內野守備和打擊兩方面持續進步，成為攻守兼備的多功能內野手。
Player: Yu-En Kuo
School: Taipei Chongqing Junior High School Position: Shortstop / First Base B/T: RHP / RHH Ht/Wt: 5'10" / 166.7 lbs Running Speed 60-Yard Dash: 7.8 seconds Arm Strength and Fielding Infield Arm Velocity: 69 mph Fielding Footwork: Stable and fluid Ball Handling: Generally reliable, but improvements in finer details of glove work are needed Hitting Data Sweet Spot %: 25% Max Exit Velocity: 89 mph Avg Exit Velocity: 77.7 mph Max Distance: 253 ft Launch Profile: 50% fly balls, 50% ground balls
Overall Evaluation
Yu-En Kuo possesses a well-balanced frame with room for physical growth and strength development. His hitting metrics, particularly his max exit velocity of 89 mph and max distance of 253 feet, indicate strong power potential. However, his Sweet Spot percentage suggests a need to improve hitting accuracy to enhance consistency and productivity at the plate. Defensively, Kuo shows stable footwork and solid judgment in handling plays. While his arm strength is average for his position, it is adequate for roles at shortstop and first base. Enhancing his throwing power and accuracy would elevate his defensive impact. Additionally, refining his glove work would improve overall fielding performance. Kuo has shown promising foundational skills for his age. With further physical and technical development, he has the potential to grow into a versatile and effective two-way infielder, excelling in both defense and offense.
