Situational hitting has been a team-wide problem for more than a few seasons now. We can clearly score runs knocking the ball out of the yard, but driving in runners in some other manner is highly problematic and their usual inability to do so is highly frustrating for us fans.
While pitching in general, and the bullpen specifically, is IMHO still the team's biggest concern, I believe that somehow addressing that weakness needs to be done. However, how to accomplish that is up for debate and is something I don't have a good feeling for right now.
