綜合評價
曾乙倫展現出一名高潛力投手的各項素質。他的直球表現強勁，轉速高且垂直位移出色，具有卡特效果，使得他的直球對打者極具威脅，並具備未來進一步提升的空間。滑球的橫向位移與曲球的多重變化性，使得他在變化球方面也表現不俗，具備極強的欺騙性。特別是曲球，旋轉效率達到99%，其位移量的數值亦顯示出該球種具有極大的壓制力。變速球的表現也非常出色，尤其在速度與旋轉效率上，未來若能在速度差異上與直球形成更明顯的落差，將為打者帶來更大的挑戰。總體來看，曾乙倫是一位多樣化且具備高度威脅的投手。

Overall Evaluation
Allen Tseng demonstrates the attributes of a high-potential pitcher with a diverse arsenal. His fastball stands out for its high spin rate, significant vertical break, and natural cutter-like movement, making it a formidable pitch with room for further improvement. His slider shows strong horizontal movement, while his curveball displays exceptional versatility and deception. The curveball, with a spin efficiency of 99%, is particularly impressive, offering outstanding movement and significant suppressive power against hitters. The changeup complements his repertoire, excelling in spin efficiency and movement. With further refinement to enhance the velocity differential from his fastball, it has the potential to become a highly effective secondary offering. Overall, Tseng’s combination of a powerful fastball, deceptive breaking balls, and a promising changeup makes him a dynamic and highly threatening pitcher. His ability to generate significant movement and deception positions him as a versatile pitcher with considerable developmental upside.
