running down the 1st baseline

[fastballb]

A slapper bunts a ball from the left side, which is fielded by the catcher just in front of homeplate.While running to 1st base the slapper is not in the 3 foot runner lane, but instead she is running directly on the foul line or the correct term "fair line". As the catcher throws to 1st the ball hits the runner in the back. Since the runner is not in the running lane is she out?? Since she was kicking up chalk at the time she was hit, is there no call??? And when if any does an umpire rule that the catcher intentionally threw at the runner in hopes of getting the call and warns the catcher???? A question for the good umpires...
