Jose Alvarez stood in front of his temporary locker in the Detroit clubhouse and answered questions with the same relaxed poise he showed on the mound. "Tried to control the emotions the most I can," the 24-year-old left-hander said. "Trust myself. I was pretty happy, this outing in the big leagues." Alvarez pitched six impressive innings in his major league debut, making the most of a one-day audition with the Tigers in Sunday's 4-1 victory over the Cleveland Indians. He was called up to make this start when Anibal Sanchez's shoulder acted up. Then after the game, Alvarez was sent back to the minors -- but not before he impressed his manager, his teammates and a sellout crowd of 41,262.
