Shaw (foot) will start at first base Saturday against the Rays, Scott Lauber of ESPN Boston reports.

EDGE Analysis

Shaw had been dealing with a foot injury, but he entered Friday night's game as a replacement for the injured Hanley Ramirez, who fouled a ball of his left shin. With just two games before the All-Star break, the Red Sox may opt to give Ramirez a rest day on Sunday as well.
