Danny Hultzen can only watch. In front of him, stretched down the foul line of Field No. 1 at the Mariners' complex, his fellow pitchers play catch during spring training. It's a daily ritual in pitcher's life. There is talk, laughter and the repetitive pop of baseballs striking leather gloves. Dressed in his full uniform, glove on his right hand, baseball in his left and a hopeful look on his face, Hultzen stands on the side as a spectator.
