Jackson will start at catcher and bat ninth in Wednesday's game against the Mariners, Marc Topkin of the Tampa Bay Times reports.
Jackson will get a turn behind the plate while top backstop Ben Rortvedt rests for the day game after a night game. Since his call-up from Triple-A Durham on May 3, Jackson is hitting a lowly .081/.159/.161 with 31 strikeouts in 70 plate appearances.
