This is where things starts to get tough.
Phil Hughes has spent most of this season on the DL due to a dead arm injury. His first three starts before the injury were just awful, as Hughes gave up 16 earned runs with a 13.94 ERA over three games.
This slow start was a direct result of the dead arm injury that kept Hughes out for all of May and June.
However, Hughes didn't exactly come back to his normal self right away either. In his first four starts back from the injury, he was 1-2 with a 5.48 ERA.
But in his last start, Hughes reminded everyone what he can do.
Hughes struck out four, allowing just three hits in six innings of no-run ball. The game was shortened due to rain, but Hughes (who had 65 pitches at the end of the sixth) looked like he would finish the game.
Being honest, Phil Hughes only has one game where you could say, "Hughes is a better pitcher than Burnett". Hughes needs to repeat his performance before anyone can say truly that he's better.
But as of now, Phil Hughes has lots of potential to turn his season around and be a good pitcher for the Yankees. Meanwhile, Burnett hasn't show any signs that would make you believe that he will turn his season around. Burnett hasn’t given anyone the reason to believe that he’s better than Hughes. Hughes has given reason for the opposite.
Right now, I would say Hughes is better than Burnett.
