The rules discussed include the infield fly rule (we eliminate an infield fly possibility, because only first base was occupied with less than two out [e.g., not first and second or bases loaded]), Official Baseball Rule 6.01(a)(10) fielder protection on a batted ball against batter/runner interference (Guerrero was the protected fielder entitled to field this fly ball), OBR 5.09(a)(12) the intentional drop rule (dead ball, batter is out -- only occurs if the fielder TOUCHES the ball before intentionally dropping it...Guerrero didn't touch the fly ball), and OBR 5.09(b)(6)the force being removed on the lead runner when the batter was retired which necessitated a tag of the runner instead of the base.
