綜合評價
賴謙凡是一位具有出色潛力的高中投手。在直球方面，賴謙凡的數據極為亮眼，無論是速度、轉速還是垂直位移，都顯示出他具備強大的直球威脅。其直球的旋轉效率高達99，顯示出其高效的投球技術，並且能夠穩定掌控投球區域（Zone 100%），讓打者很難應對。 滑球雖然目前表現尚有提升空間，但其潛力不容忽視。垂直位移和橫向位移的數據顯示出它在與打者對決時能夠造成一定的迷惑效應，若能加強旋轉效率及球路的穩定性，未來有望發展成更具威脅性的球種。指叉球的橫向位移表現也是賴謙凡的亮點，並且出手延伸數據顯示他能有效地運用這顆球來操控比賽，若轉速和控球進一步提升，將成為他投球武器中的一顆重要球種。總體而言，賴謙凡是一位具備極大發展潛力的投手，尤其是在直球的威脅性上，他的數據已經達到很高的水準。隨著滑球和指叉球的進一步提升，他將擁有成為頂尖投手的潛力。

Overall Evaluation
QIAN-FAN LAI is a high school pitcher with significant potential. His fastball is a standout pitch, featuring excellent velocity, spin rate, and vertical movement. With a spin efficiency of 99% and Zone% at 100%, his fastball is highly effective and challenging for hitters to handle. The slider shows potential but requires further refinement. Its vertical and horizontal movement can disrupt hitters, and with improvements in spin efficiency and consistency, it could become a more threatening pitch. The split-finger fastball stands out for its horizontal movement, and the extension data suggests it is effectively used to control the game. Further development in spin rate and control could elevate it to a critical weapon in his arsenal. Overall, Chien-Fan Lai demonstrates strong potential, especially with his impactful fastball. With continued development of his slider and split-finger fastball, he has the tools to grow into a top-tier pitcher.
