李國璋表示，根據該報告指出，新竹棒球場場地的表土層沒有提供足夠的排水性能（The soil materials selected for this project do not provide adequate drainage performance.），並且該土層難以維持職業棒球所需的高品質草皮（This layer makes it difficult for staff to maintain high quality turfgrass needed for professional baseball），且當該表土層因天氣炎熱變得緻密並乾燥時，會非常堅硬，「增加球員在場地接觸受傷的風險」（When the surface layer becomes compact and dry it becomes excessively hard. This condition creates an increased risk for player to field contact injuries.）。
李國璋指出，該報告還寫到，新竹棒球場場地的清碎石層含有細小的石塵顆粒，這些顆粒會鎖住並壓實，防止水進入位於該層下方的排水系統（The stone contains fine stone dust particles that lock up and compact, preventing water from entering the drainage system which is located below this layer.），「這種材料通常不被批准作為運動場場地的生長介質或排水材料」！（This material is not typically used in athletic field construction as an approved growing media or drainage material.）
宋品瑩表示，美國大聯盟相關專家針對場內土壤材料檢視結果是「成分不符合專業、校園和休閒內場混合設計的一般標準」（The composition of this material does not meet general standards for professional, high school or parks and recreational infield mix design. The ratio of sand, silt and clay does not comply with industry standards for baseball infield mix.），更誇張的是「比賽場地不符合職業棒球的規則和規定」（The playing field does not comply with rules and regulations for professional baseball.），投手丘高度和距離都不正確（Both the mound height and distance were incorrect）、投手丘至部份壘包間的坡度百分比均有問題。
