In other words, he's a loser and needs to go to the bullpen or into rehab or whatever.
I do understand the point that the Sox are paying him $10M. Thus someone else's comment he should get 10 starts before any change is made. After all, he's an investment.
However, my furor at keeping him in the rotation is that starters and only starters can make a huge difference in winning and losing. It used to be--and often still is--that managers would leave starters in until they had given up 7 runs. Why? Because you want to get some innings out of your starter, even one who gets off to a bad start. And, of course, right now the Sox are well into playing 19 games without a break.
My furor is strengthened by the realization that we know five other starters are better and that Bello has more potential right now than a veteran clearly in decline.
