Glasnow (back) will start Tuesday's game against Atlanta, Fabian Ardaya of The Athletic reports.
Glasnow has been out since May 8 due to lower-back spasms, but he's performed tremendously during his four minor-league rehab starts, allowing just two runs on three hits and four walks while striking out 20 batters over 13.2 innings. He built up to 77 pitches during his most recent outing at Triple-A, so he likely won't be operating under a heavy workload restriction while he makes his first MLB start in nearly four months. He'll also benefit from facing an Atlanta lineup that's posted just a .590 OPS across its last 10 games.
