Schwarber's absence from the lineup for Tuesday's game against the Marlins is due to a gastrointestinal issue, Matt Gelb of The Athletic reports.
Schwarber's omission from Tuesday's starting nine is notable since he rarely gets days off, so it's not a major surprise that he's feeling less than 100 percent. The veteran slugger should be considered day-to-day while Bryce Harper shifts to designated hitter.
