Because too many players are simply not very good, historically, and are slumping as they return to nearer their career averages. You think Gonzales, Toro, Narvaez, Wong, Rafaela etc will suddenly turn it around and outperform their career averages? You saw what happened last night: bases loaded, nobody out, no runs. How many times did we fail to score with RISP? The problem IMO will be scoring runs going forward. Its why we will likely NOT make the playoffs this year.
