Jean Segura reaches base, steals second base.
Cubs intentionally walk Braun.
Segura takes off early to steal third and is caught in a rundown.
During the rundown he returns to second, where Braun is already standing.
Braun is out by rule, but Segura thinks he is the one out so gets up and continues to first base, where he reaches safely.
So two out now, Segura on first. Segura attempts to steal second and is thrown out.
