Gonzalez left Tuesday's spring training game versus the Padres due to tightness in his lower back.
Gonzalez took the mound in the top half of the seventh inning, and he struck out his first batter but then allowed a single and three consecutive walks. He departed the game after walking in a run on what turned out to be his final batter. The White Sox labeled the righty as day-to-day after his exit.
