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.

綜合評價
曾亦誠是一位投手，兼具外野守備能力，並展現出一定的打擊潛力。他的投球方面，擁有穩定的直球及發展中的變化球，尤其是直球具備較強的垂直位移與自然卡特效果，對於右打者能夠發揮有效威脅。滑球與曲球的發展則顯示出一定的潛力，但兩者在速度與位移的重疊上可能需要進一步的調整與多樣化。在擊球方面，曾亦誠具有穩定的擊球質量，並且能擊出一定距離的球，不過未來可進一步提升擊球初速及加強爆發力，並在擊球類型上進行更多變化。總體來看，曾亦誠具備發展成為兩棲型選手的潛力，無論是在投球還是打擊上，都有明顯的進步空間。

Overall Evaluation
I-Chen Tseng is a versatile player who excels as a pitcher while showing potential in outfield defense and hitting. His fastball stands out with strong vertical movement and natural cutter action, posing a significant challenge to right-handed hitters. Both his slider and curveball exhibit potential, though adjustments are needed to differentiate their speeds and movements for greater effectiveness and diversity. Offensively, Tseng demonstrates consistent hitting quality, with a high Sweet Spot percentage and the ability to generate decent distance. Future improvements in exit velocity and power output, along with more varied batted ball profiles, could significantly enhance his offensive impact. Overall, Tseng possesses the tools to develop into a two-way player. With continued refinement in both pitching and hitting, he has considerable room for growth and the potential to contribute in multiple facets of the game.
