The starters -- Let's end the Fifth Starter myth. This team cannot afford to continue to trot out so-called "fifth starters" for 30 games a year. Over the last few seasons those fifth starter outings have wrecked the team ERA. This year's Fogg/Belisle/Bailey numbers are in the 7 plus ERA range.
There are currently four capable starters but only Volquez has real ground ball tendencies. At GABP, ground ball guys should be emphasized where possible.
We've seen over the last few weeks how consistent pitching can keep the team in games, even with its (temporarily) weaker offense. So the Reds should add another good starter, someone with ground ball tendencies. Lowe of the Dodgers (a free agent I think) would be ideal.
I know other teams have "fifth starters." But it just doesn't work with the Reds. Another "real" starter is the way to go. A ground ball guy.
The bullpen -- Instead of keeping a "long man" (really a sixth starter) who hardly ever pitches, the Reds need more workhorse type relievers who can throw multiple innings. For next year, Massett, Ramon Ramirez, and Micah Owings look to be guys who maybe can fill that role. Affeldt can from the left side, if they keep him, or else a lefty replacement is needed.
With Cordero, Burton, maybe Roenicke, Bray, maybe Weathers, maybe Herrera, I think the "short man" end is covered. But the pen should be filled out with pitchers who can throw two or three innings and do it often.
