In real life, Jack Cust leads the team with 7 homeruns, but check out Holliday's stats.
My game:
Matt Holliday - ( 50 games) .263/6/18/SO 28/SB 3/5 2B
Real life:
Matt Holliday - .(46 games) .264/6/28/SO 29/SB 3/6 2B
Of course, not everyone in the lineup's stats are this close, but as least I know the game is playing well. But to answer your question, there won't be much power coming out of this team all year, unless someone just goes on a tear.

While not having quite the monster year he's having in real life, it looks as though Jason Bay is pulling his weight (in my game) this year too.
