Yelich hit 2 HRs in a game on August 21st.
Other than that game, he hasn't in a home run in another of his other last 40 games.
He also has only two doubles in the last 55 at-bats, with no other extra-base hits.
His slugging percentage so far this month is 245.
August looked like he was getting into at least a bit of a groove.
There has to be something wrong health-wise. Is the back still a problem ?
