If he used Foster after Heuer with the bases empty instead of trying Rodon there, we might be talking about taking on Houston next week. But it's possible Foster would have not been able to find the plate in either scenario. But of course hindsight is 20/20. Having so many rookies in your bullpen for a pressure packed game is tough.
To be honest, I am still pretty upset that Keuchel did not get the job done in game 2 (the type of game we brought him in for as a free agent) to make game 3 unnecessary.
