Glasnow (shoulder) threw a side session Tuesday without issue and will throw another such session before throwing a simulated game, the Pittsburgh Tribune's Rob Biertempfel reports.
He seems to be progressing well, but there are still several hurdles he has to clear before his activation from the DL. The Pirates have some pretty low-grade options in the rotation right now, so Glasnow would figure to get some starts down the stretch if he can return to full health. Control issues have plagued him at every stop, but he has maintained an elite K-rate, making him a high-risk/high-reward option in single season leagues.
