Fastball
Hop+
A fastball with hop has a flat approach angle and visually jumps through the zone. When thrown up in the zone, it is more likely to generate a higher swing and miss average. Hop+ of 100 is MLB average.
Fastball
Sink+
A fastball with sink has low backspin and drops through the strike zone. When thrown down in the zone, it is more likely to generate a higher ground ball percentage and lower launch angle. Sink+ of 100 is MLB average.
Fastball
Rise+
A fastball with rise has a high percentage of backspin. When thrown up in the zone, it is more likely to generate a higher fly ball percentage. Rise+ of 100 is MLB average
Curveball
Hammer+
A hammer breaking ball drops vertically with velocity through the zone, or 12-to-6 movement. Hammer+ of 100 is MLB average.
Curveball
Sweep+
A sweeping breaking ball moves horizontally with velocity through the zone. Sweep+ of 100 is MLB average.

球探報告：鄭以諾
基本資料 學校：新北鶯歌高級工商職業學校 守備位置：投手 投打習性：右投（高壓類型） / 右打 身高 / 體重：6呎0吋 / 192.7磅 擁有標準且結實的投手體型 數據分析 直球 速度範圍：83.3 ~ 85.8 英里（最快 85.8 英里） 轉速：最快 2431 RPM，平均 2361 RPM（轉速突出） 垂直位移：最大 20.2 英吋，平均 16.8 英吋 橫向位移：自然跑卡特效果，接近垂直線軸，橫向位移極少 出手延伸：6.8 英呎 鄭以諾的直球以其出色的垂直位移表現為亮點，數值在同年齡層中相當突出，尤其是最大與平均數據均表現穩定，顯示出直球有不錯的上升錯覺，對打者形成壓迫。其自然的跑卡特效果也讓直球更加難以掌握 滑球 速度範圍：82.2 ~ 83.8 英里（最快 83.8 英里） 轉速：最快 2468 RPM，平均 2442 RPM（轉速突出） 垂直位移：最大 7.3 英吋，平均 6.5 英吋 橫向位移：最大 -5.8 英吋，平均 -6.2 英吋 出手延伸：6.5 英呎 曲球 速度範圍：68.4 ~ 70.1 英里（最快 70.4 英里） 轉速：最快 2269 RPM，平均 2137 RPM 垂直位移：最大 -10.6 英吋，平均 -11.6 英吋 橫向位移：最大 -7.4 英吋，平均 -11.3 英吋 出手延伸：5.8 英呎 旋轉效率：91%
綜合評價
鄭以諾是一名極具潛力的高中投手，具備完整的三種主要球路：直球、滑球與曲球。每種球路的數據表現均高於同年齡層的平均水平，特別是在轉速與位移數據上展現出極大的潛能。他的直球具有自然的跑卡特效果，結合高垂直位移，讓打者難以有效掌握揮棒點；滑球則具備發展成更高階變化球的潛力，未來有望成為核心壓制球路；曲球旋轉效率與位移數據優秀，可作為速差誘打球進一步強化投球策略在出手延伸上，鄭以諾的數據（6.8英呎）顯示他的投球姿勢具有良好的節奏性與穩定性，使得每顆球的有效投射距離對打者形成更大的壓迫感。

Overall Evaluation
Yi-Nuo Jheng is a highly promising high school pitcher with a complete arsenal of three primary pitches: fastball, slider, and curveball. His pitch metrics consistently exceed the average for his age group, particularly in spin rate and movement. His fastball features outstanding vertical break combined with a natural cutting action, making it difficult for hitters to barrel effectively. The slider shows the potential to evolve into a dominant breaking pitch with its high spin rate and horizontal movement. The curveball, with excellent spin efficiency and significant vertical drop, serves as a strong change-of-pace option to induce swings and misses. Jheng’s extension of 6.8 feet highlights his rhythmic and stable pitching mechanics, increasing the perceived velocity and deception of his pitches, adding to his effectiveness on the mound.
