Assume runner on first, no one out. Batter hits a high fly ball to dead center. While running, he turns first and happens to pass the runner on first (we'll assume it's Bartolo Colon running with two broken ankles and a pulled hammy). The ball is then caught on the warning track. Is the runner on first out for being passed before the ball was caught?

Similar scenario, runners on first and second (theoretical cripptolo on second), runner on first passes the runner on second before the ball is caught. Who's out?

Edit: I was wrong about which runner would be out, but at least I'm less wrong than my friend who argued that no one except the batter would be called out.
