綜合評價
鄭裕豐是一位身高具優勢且體型強壯的右投手，他的體格使他在投球時擁有穩定的力量輸出，並且能夠有效控制投球的伸展性。雖然他的直球速度較為中等，但他的球速穩定且轉速高，讓直球的垂直位移成為其投球的重要特點，並能夠在對抗打者時創造威脅。他的曲球與滑球作為輔助球路，滑球的位移尤其值得注意，未來有潛力發展成為具威脅的變化球，並且能與直球形成良好的配球搭配。指叉球則具有一定的垂直位移，這讓他能在比賽中有效應對不同的打者。鄭裕豐的整體投球組合具備了發展潛力，尤其在配球上具備未來的進步空間。總體來說，鄭裕豐在投球方面具有不錯的發展潛力，值得關注其後續成長。

Overall Evaluation
Zheng Yufeng is a right-handed pitcher with a physically advantageous and strong build, allowing him to deliver consistent power and maintain effective pitching extension. While his fastball velocity is moderate, its stability and high spin rate contribute to notable vertical movement, making it a key weapon in challenging hitters. His breaking pitches, particularly the slider, display promising lateral movement, showing potential to evolve into a highly effective secondary pitch when paired with his fastball. The forkball adds another layer of complexity to his arsenal, offering vertical break to counter various hitters effectively. Zheng’s overall pitching repertoire showcases significant developmental potential, especially in refining his pitch sequencing and maximizing the effectiveness of his secondary offerings. As he continues to mature and fine-tune his mechanics, Zheng Yufeng is poised to become a more formidable presence on the mound, warranting close attention to his ongoing progress.
