Ross went 2-for-4 with a solo homer and two runs scored overall in Friday's 12-1 victory over the Mariners.
The veteran backstop kick-started a six-run sixth for the Cubs, blasting a 382-foot solo shot to left center off Nate Karns. Ross has played very sparingly in July after suffering a concussion early in the month, logging only 14 at-bats, three hits and two RBI.
