Smoker was optioned to Triple-A Las Vegas on Tuesday, Anthony DiComo of MLB.com reports.
EDGE Analysis
Smoker has struggled mightily as of late, posting a 13.50 ERA and 2.05 WHIP over his last seven appearances, and with Matt Harvey returning from his team-imposed suspension, he'll head back to the minors to work on his stuff. The 28-year-old reliever did get his ERA down to 2.45 earlier in the season, so if he finds success with the 51's, it wouldn't be too surprising to see him return to the majors relatively soon.
