綜合評價
羅于晏是一名在打擊與投球方面都具備潛力的多面手選手。作為游擊手，他的速度（60碼衝刺跑：7.30秒）及內野臂力速度（79英里）均顯示出他具備很好的防守範圍，能夠快速反應並處理各種防守情況。他的擊球表現穩定，但在提升方面仍有空間。未來，他可以專注於提高擊球精準度和穩定性，進一步發揮其打擊潛力。作為投手，羅于晏擁有相對穩定的直球表現，並且擁有不錯的旋轉效率（94%），這使他的直球對打者形成一定威脅。雖然他的曲球主要以橫向位移為主，但透過調整和修正，未來可以使其更具迷惑性。變速球在垂直與橫向位移上顯示出良好的潛力，未來有機會成為他的一項主力武器。 總體來看，隨著技術的提升，他有望在防守與投球上穩定發揮，並在打擊端提升表現，成為具競爭力的選手。

Overall Evaluation
YU-YAN LUO is a versatile player with potential in both hitting and pitching. As a shortstop, his speed (7.30 sec in the 60-yard dash) and arm strength (79 mph) provide him with solid defensive range and reaction capabilities. However, his hitting requires improvement, particularly in Sweet Spot % (20%) and hitting distance, which are currently below average. Developing better contact and consistency at the plate will enhance his offensive impact. On the mound, Luo showcases a steady fastball with impressive spin efficiency (94%), creating difficulty for hitters. His curveball emphasizes horizontal movement, and with further refinement, it could become a more deceptive weapon. His changeup shows strong potential, with significant vertical and horizontal movement, and could become a key part of his pitching arsenal. Overall, Luo has a balanced skill set with room for growth in both defense and pitching, as well as in his hitting performance. With continued development, he has the potential to become a competitive and impactful player.
