Forgive me a little late-season rosterbation.
The problems: 4 major-league quality starting pitchers for 5 spots. 92 major-league quality relievers for 7 spots. OK, maybe not quite 92, but close.
The solution: 4 man rotation. Dump Ho, bring back Lowe. Get Feierabend, Mickolio (when he's healthy, dumping Rivera from the 40-man) and Huber (when he's healthy) to travel with the team for the next couple of weeks, swapping parts out as they tire until they can be added to the active roster for the rest of the regular season. If things get desperate, there is enough dead wood on the 40-man roster to add the best of Rohrbaugh, Campillo or even Woods. Baek will be back in a few weeks as well.
Stock that bullpen full and limit the starters to 5 innings/80 pitches. Hell, with the Ho gone, it's not even that much more work on the pen than it's getting now. Get creative. Just slap the Ho to the curb.
