Yes, but Estrada could have been asked to bunt. Also, if the Brewers would score something like 3-4 runs in the inning, you could send Estrada back out there and try to steal another inning of work. The bullpen could still be ready in case of no runs scored or if Estrada got into trouble. Edit: Of course, Estrada could have told Roenicke that he was completely done, but we wouldn't have that info.
