Atlanta manager Walt Weiss confirmed that Waldrep will start Thursday's game against the Cardinals, Mark Bowman of MLB.com reports.
Waldrep made his 2026 debut with Atlanta last Friday, pitching two innings of relief behind starter Reynaldo Lopez. Both pitchers will be in the rotation this week, as Bryce Elder will have his turn skipped. Though Elder is expected to return to the rotation next week, Waldrep could end up sticking around in a starting role, as Atlanta is contemplating moving Grant Holmes to the bullpen. Waldrep's performance Thursday will likely influence that decision, though the right-hander shouldn't be expected to work more than five or six innings, regardless of how well he's pitching. Since completing his recovery from a Feb. 23 elbow procedure and beginning a rehab stint at the beginning of June, Waldrep hasn't tossed more than 71 pitches or covered more than 4.2 innings in any outing.
