Dodgers optioned RHP Bobby Miller to Triple-A Oklahoma City.

Miller draws the short straw from a roster construction standpoint with Los Angeles needing to free up a spot for Emmet Sheehan. The 27-year-old showed well in his return to the big leagues, allowing one run over three innings to pick up a win in relief against the Nationals on Sunday. He figures to return at some point before the regular season concludes.
