Kevin Brown summed it up "When they hit, they don't pitch; when they pitch, they don't hit." We've had some decent individual performances over this long losing streak, but we can't put together decent pitching and decent hitting on the same night.
If our offense puts up a decent showing, our pitchers can't keep the opponent off the bases and they outscore us.
If our pitchers throw a hell of a game, our offense comes up small.
Winning teams find a way to sync up (through luck or otherwise) good pitching and good hitting nights. We're looking less and less like a winning team.
