The Yankees took a 2-0 lead in the first inning off of RBI-singles from Eric Chavez and Curtis Granderson.
Granderson extended that lead to 5-0 in the third inning with a home run that scored Chavez and Robinson Cano.
The Yankees made it 7-0 in the fourth with an RBI-single by Nick Swisher followed by a Mark Teixeira sac fly.
Both benches were warned, as three batters have already been hit -- Teixeira and Prince Fielder in the first, then Robinson Cano in the third.
Tigers starter Anibal Sanchez was pulled for Duane Below after Swisher's RBI-single. He gave up seven hits and seven earned runs and struck out two in three innings.
Brennan Boesch cut the lead to 7-1 in the bottom of the fourth.
