Motter will bat leadoff Tuesday against the Diamondbacks, Marc Topkin of the Tampa Bay Times reports.
Mikie Mahtook will move down in the lineup and act more as a run producer with some of the heavy lifters (Evan Longoria, Steve Pearce, Steve Souza) on the bench, affording Motter his first career start atop the order. Motter turned in his second multi-hit game Monday, but he doesn't have an extra-base hit since May 22.
