The Washington Nationals sent prospect Seth Romero home Monday morning for violating club policy, according to a source.

While Romero was dismissed for violating team guidelines, he did not break any Major League rules.

Romero was a first-round pick of the Nationals last June. His draft stock took a hit following a tumultuous junior year at the University of Houston.

The 21-year-old was suspended for the first two weeks of the 2017 season for conduct detrimental to the team. He was later suspended again, with the Houston Chronicle reporting the suspension stemmed from a failed drug test. A third incident in May of 2017 led to his dismissal from the Houston program.
