Kiermaier is out of the lineup Sunday against the Red Sox, Marc Topkin of the Tampa Bay Times reports. Kiermaier usually finds himself at the top of the order against right-handed pitchers such as Boston's Justin Masterson, but with manager Kevin Cash wanting to get a glimpse at the newly added Grady Sizemore, there's not enough space in the lineup. Considering that Sizemore struggled mightily with the Phillies earlier this season and looks to be nearing the end of his career, it doesn't appear that Kiermaier's hold on the large end of the center-field platoon is threatened.
