New Tigers' starting pitcher Dontrelle Willis admitted on Friday that he has to improve his performances, according to the Detroit News. He has walked 10 people and allowed nine earned runs in his last 8 2/3 innings. "I have to do a better job of going out there and making guys hit the ball," Willis said. "It doesn't matter how hard you throw, I just want guys to swing and swing early. I haven't been doing that." "I never shy away from calling it as I see it. ? I just didn't do my job today. It could have been a whole lot worse, but that doesn't mean I can't do my job. I feel strong, though. I would tell you if I didn't," he added.
