Glasnow (shoulder) will make a rehab start Sunday with Double-A Altoona, the Pittsburgh Post-Gazette's Bill Brink reports.
First he will have to make it through a side session Thursday, but assuming that goes well, he will make a four-inning, 65-70 pitch start for the Pirates' Double-A affiliate on Sunday. He threw a 50-pitch bullpen session Tuesday. There has been no word as to whether Glasnow will need multiple rehab starts before being activated and it is also unclear if he will join the Pirates' rotation immediately or head to Triple-A. That said, given Glasnow's upside and the fact that he could reasonably be starting for the Pirates by next weekend, he should still be rostered in most formats.
