NFHS Rule 2.29 Infield Fly Rule (excerpt)
Infield fly is...a fair fly ball that can (not should) be caught by an infielder with ordinary effort...
A coach/manager would be hard pressed to convince me that his fielder gave less than ordinary effort after the fact that the ball was dropped. Wind/sun can change what constitutes ordinary effort. Point is the umpires screwed up, that is a given. But, the fact the ball was NOT caught is justification that the fielder could not catch the ball with ordinary effort.
