For anyone who was wondering, it has now been 21 games, spanning 82 at-bats, since Derrek Lee has homered. His last homer came on June 3.
Now it's nice that he's batting .350, but I didn't expect him to turn into Rod Carew this year, and I doubt anyone else did, either. With Barrett gone, and now Jones probably being traded (not that he was hitting homers, anyway), the Cubs really need Lee to start hitting with some pop again.
The six homers he's had so far this year put him on pace for around 13. We need more than that from Lee. It's possible, I suppose, that his injury from last year is affecting his power. I can't think of any other reason.
