Palumbo will be recalled from Triple-A Nashville on Tuesday to start the first game of a doubleheader with the Angels.
Texas initially planned to recall Palumbo from Nashville to start the night game, but manager Chris Woodward opted to have the 24-year-old lefty and Brock Burke -- who will also be called up Tuesday -- swap spots in the pitching schedule. The Rangers will need a fifth starter again this weekend versus the White Sox, so the performance of both pitchers in the doubleheader will probably have significant sway in determining which of the two sticks around with the big club.
