綜合評價
劉益晨作為一名右投投手，展現了不錯的投球潛力，特別是在直球、滑球和變速球的發展上，他的各種球路數據都顯示出有潛力成為一位多樣化的投手。他的直球速度穩定在82.7到85.2英里之間，最大垂直位移可達19.7英寸，這使得他可以在投手丘上對打者產生良好的垂直壓迫感。此外，劉益晨的直球命中率也非常出色，達到71%，顯示出他的投球控制能力有一定的穩定性。在滑球方面，雖然目前以橫向位移為主（最大橫向位移為-14.5英寸），劉益晨的旋轉效率達58%，屬於不錯的表現。未來若能調整其滑球的垂直位移並持續提升旋轉效率，將能進一步增強滑球的威脅性，並讓他成為打者更加難以攻克的投球武器。變速球的數據顯示出劉益晨在速差的運用上已經具備一定的優勢，速差與直球形成明顯的對比，且具有相對較高的旋轉效率（82%）。最大橫向位移達19.6英寸，顯示出變速球具有顯著的橫向變化，與其直球搭配使用能夠有效增加打者的判斷難度。變速球的垂直位移也不錯，並且出手延伸長達6.5英尺，顯示他對於打者的逼迫有不小的優勢。總體來看，劉益晨的投球武器在多樣化球路方面表現突出，尤其是在直球和變速球的結合使用上，已具備一定的競爭力。

Overall Evaluation
Yi-Chen Liu shows promising potential as a right-handed pitcher, with diverse pitch options and solid data across his arsenal. Fastball: His fastball consistently reaches 82.7–85.2 mph, with a vertical break up to 19.7 inches and a Zone % of 71%, demonstrating strong control and effectiveness in pressuring hitters vertically. Slider: Primarily focused on horizontal movement with a maximum horizontal break of -14.5 inches, his slider has a spin efficiency of 58%. Adjusting for greater vertical movement and improving efficiency could make it a more potent weapon. Changeup: With a clear speed differential from the fastball and a high spin efficiency of 82%, his changeup adds a deceptive element to his repertoire. Its significant horizontal break (max 19.6 inches) and extended release point of 6.5 feet enhance its ability to disrupt hitters’ timing. Liu's ability to combine his fastball and changeup effectively, coupled with potential improvements to his slider, positions him as a competitive and versatile pitcher. Enhancing pitch movement and control will further elevate his performance.
