Seattle had 12 blown saves in the entire 2014 season, but now has 14 in the first 105 games of 2015 while struggling to a 47-58 record.
Handed a 2-1 lead, Smith gave up a first-pitch leadoff double to Miguel Sano. The 26-year-old struck out Trevor Plouffe, but then uncorked a wild pitch up by Torii Hunter's head that allowed pinch-runner Shane Robinson to take third.
Smith appeared close to getting out of the jam when he got Hunter on a comebacker to the mound.
