Palumbo permitted four runs on six hits over four innings in a no-decision in the first game of a doubleheader against Oakland on Saturday. He struck out four and did not issue a walk.
Making his major-league debut, Palumbo kept the Athletics off the board over the first three innings. However, the 24-year-old ran into trouble in the fourth inning, as Matt Olson belted a two-run homer and Josh Phegley added a two-run double. Palumbo is not current scheduled for his next major-league start.
