When a player attempts to steal second and the catcher does not throw the ball, what is the ruling?

In the scenario where a player attempts to steal second base and the catcher does not make a throw, the appropriate ruling is that the player is considered safe at second base.

When a runner attempts a steal and successfully reaches the base without being tagged out, the play is allowed to continue. The absence of a throw by the catcher indicates that there was no defensive play that could have resulted in an out, allowing the runner to advance freely. This aligns with the rules governing base-running and stealing, recognizing the runner's right to advance if they reach the base without interference or obstruction.

The situation also implies that there are no other complicating factors such as a pitch being made that would lead to other scenarios impacting the runner's status. Hence, the ruling stands firm with the runner being safe at second base.
