With an 8-1 lead in the 5th inning, I think it's safe to assume that they will be 3-0 after tonight. Furthermore, they have hit another 6 HRs tonight to give them 14 for the season. At this pace, they would hit 756 HRs this year.
Considering that the major league record for HRs in a season by a team is 264, I don't think they will keep up this pace, but they could make a run at that record. BTW, the Tiger record is 225.
