Mariners emergency starter Vidal Nuno walked the leadoff batter for the second straight inning — but this time he escaped without giving up a run.
The Tigers lead 2-0 entering the top of the fourth.
In the bottom of the third, Ian Kinsler drew a four-pitch walk to start the inning. But Jose Iglesias tried to lay a sacrifice bunt and popped out to first base.
From there, Miguel Cabrera struck out looking and Nick Castellanos flied out.
Nuno has given up three hits and two walks. He gave up back-to-back RBI doubles in the second inning to Justin Upton and Steven Moya.
