Palacios will start at second base and bat seventh in Wednesday's game against the White Sox, Marc Topkin of the Tampa Bay Times reports.
The left-handed-hitting Palacios has now drawn the last two starts at second base over the right-handed-hitting Ben Williamson when the Rays have faced right-handed pitchers. The two could form a loose platoon at the keystone until Tampa Bay gets Gavin Lux (shoulder/ankle) back from the injured list.
