Question Of The Week: Who Should Be The Yankees' Fourth Playoff Starter?

With the New York Yankees in the middle of a series with the Texas Rangers, which is a possible playoff preview, we have the postseason on the brain. Health permitting, the Yankees will pencil in CC Sabathia, Hiroki Kuroda and Andy Pettitte in the first three games of a playoff series. They'll need more than three starters, though (and who knows if Pettitte will be ready by then), which begs the question, who should be the fourth? The up-and-down Phil Hughes and Ivan Nova would be the most likely candidates, with Freddy Garcia being a long shot. And now we'll even throw Derek Lowe into the mix, as he's a playoff-tested veteran. So, at this point, who do you trust the most to start a game in the playoffs?
