If R1 maliciously crashes into the second baseman during a pop-up slide, what is the ruling?

In a situation where a runner maliciously crashes into a fielder, such as the second baseman during a pop-up slide, the ruling is that the ball is dead and the runner is typically ejected from the game. This ruling is based on the principle of player safety and the enforcement of rules against unsportsmanlike conduct. In this case, the action of R1 is deemed to be intentional and harmful, warranting an immediate response to protect the integrity of the game and the safety of the players involved.

The play being dead ensures that no further actions can occur on the field until the situation is resolved appropriately, and the ejection serves as a significant deterrent against such behavior in the future. Consistency in applying these rules helps maintain fair play and promotes sportsmanship among all players.
