Falter will remain in the Phillies' rotation once Zack Wheeler (forearm) is activated next week, Matt Gelb of The Athletic reports.
To create room for Wheeler in the rotation, the Phillies will move Noah Syndergaard to a relief role, at least in the short term. Falter has a 2.52 ERA, 0.87 WHIP and 30:3 K:BB in 35.2 innings over his last six starts. He'll pick up another start Sunday in Atlanta and tentatively lines up to face Atlanta again next weekend in Philadelphia.
