Also a runner must attempt to avoid a fielder attempting to make a play on a batted ball, even if the ball was deflected by another fielder.

It is alive and in play despite the fact that another infielder may be in position to field the ball.

This is not the case if a fielder is making a play on the ball! The runner must avoid the fielder. If the runner interferes with the fielder making a play, the runner is declared out.

Otherwise, the ball is still live and in play.
