The Astros are again using an off day to re-adjust the order of their rotation, as the Chronicle recently pointed out in an article about Brett Oberholtzer. I have written a little bit about this already this year, so further comment about what I think it all means may be in order.
So how did we get to here??
Well, the Astros have used four starters consistently all year. Dallas Keuchel and Collin McHugh were locks for the rotation given their strong performances in 2014. Scott Feldman was a lock for the rotation given his seniority, contract, and his history of reasonable effectiveness.
