Hays (kidney) could be activated off the 10-day injured list Tuesday following his rehab assignment with Triple-A Lehigh Valley over the weekend, Todd Zolecki of MLB.com reports.
Hays has been on the IL since Sept. 5 due to a kidney infection. The 29-year-old outfielder has thus far played in two games for Lehigh Valley, going 2-for-9 with one walk and three runs. Barring any setbacks, Hays could be activated ahead of Tuesday's game against the Cubs.
