The Yankees activated Davis (illness) from the 10-day injured list Friday.
Davis had battled a stomach bug prior to the All-Star break but is feeling well enough to suit up for the start of the second half. Ben Rice has been great against righties (.887 OPS) but hasn't done much versus lefties (.593 OPS), so the 31-year-old Davis will provide the Yankees with another option at first base against left-handed pitching.
